1.3 Probe
1.3.1 Probe Safety
A guard around the probe body provides a finger barrier for protection from electric

shock.

Picture 1-6

Connect the probe to the oscilloscope and connect the ground terminal to ground

before you take any measurements.

Note： ● To avoid electric shock when using the probe, keep fingers behind the guard
on the probe body.
● To avoid electric shock while using the probe, do not touch metallic
portions of the probe head while it is connected to a voltage source.
Connect the probe to the oscilloscope and connect the ground terminal to
ground before you take any measurements.

1.3.2 Probe Attenuation Setting

Probes are available with various attenuation factors which affect the vertical

scale of the signal. The Probe Check function verifies that the Probe attenuation

option matches the attenuation of the probe.

You can push a vertical menu button (such as the CH 1 MENU button), and

select the Probe option that matches the attenuation factor of your probe.

Note. The default setting for the Probe option is 1X.

Be sure that the attenuation switch on the probe matches the Probe option in the

10
 oscilloscope. Switch settings are 1X and 10X.

Note. When the attenuation switch is set to 1X, the probe limits the bandwidth of the

oscilloscope to 10MHz(according to Probe spec). To use the full bandwidth of the

oscilloscope, be sure to set the switch to 10X

1.3.3 Probe Compensation

As an alternative method to Probe Check, you can manually perform this

adjustment to match your probe to the input channel.

Picture1.3-2

1. Set the Probe option attenuation in the channel menu to 10X. Set the switch to 10X

on the probe and connect the probe to channel 1 on the oscilloscope. If you use the

probe hook-tip, ensure a proper connection by firmly inserting the tip onto the

probe.

2. Attach the probe tip to the PROBE COMP～3V connector and the reference lead

to the PROBE COMP Ground connector. Display the channel and then push the

“AUTO” button.

3. Check the shape of the displayed waveform.

 Over compensated Compensated correctly under compensated
Picture 1.3-3

4. If necessary, adjust your probe. Repeat as necessary.

1.4 Self Calibration

The self calibration routine lets you optimize the oscilloscope signal path for

maximum measurement accuracy. You can run the routine at any time but should

always run the routine if the ambient temperature changes by 5℃ or more.

To compensate the signal path, disconnect any probes or cables from the front-panel

input connectors. Then, push the UTILITY button→ “ Next Page 1/3” → “Do Self

Cal” option and follow the directions on the screen.

20
 Note：● The oscilloscope vertical response rolls off slowly above its bandwidth (60
MHz, 100 MHz) , which depending on the model, or 20 MHz when the
Bandwidth Limit option is set to “On”. Therefore, the FFT spectrum can
show valid frequency information higher than the oscilloscope bandwidth.
However, the magnitude information near or above the bandwidth will not
be accurate.
● If the channel is set to DC coupling，you can quickly measure the DC
component of the signal by simply nothing its distance from the ground
symbol.
● If the channel is set to AC coupling，the DC component of the signal is
blocked allowing you to use greater sensitivity to display the AC
component of the signal.

Setting up the CH1、CH2 Channels

Each channel has its own separate Menu. The items are set up separately

according to each channel.

1. Set up the channel couple

Take the CH1 for example, the tested signal is a sine wave signal with DC

deflection:

● Press“CH1”→“Coupling”→“AC”, Set to AC couple mode. It blocks the DC

component of the input signal.

To use the Math FFT mode, you need to perform the following tasks:

1. Set up the source (time-domain) waveform.

● Press the AUTO button to display a YT waveform.

● Turn the vertical “POSITION” knob to move the YT waveform to the center

29
vertically (zero divisions).

● Turn the horizontal “POSITION” knob to position the part of the YT waveform

that you want to analyze in the center eight divisions of the screen.

The oscilloscope calculates the FFT spectrum using the center 1024 points of the

time-domain waveform.

● Turn the “Volts/div” knob to ensure that the entire waveform remains on the

screen.

● Turn the “S/div” knob to provide the resolution you want in the FFT spectrum.

● If possible, set the oscilloscope to display many signal cycles.

To display FFT correctly, follow these steps:

1. Push the “MATH” button.

2. Set the “Operation” option to FFT.

3. Press the “Source” button to select “CH1”or “CH2”according to input signal

channel.

4. According to Nyquist law, turn the “S/div” knob to adjust the sampling rate(This

parameter is displayed behind the time base parameter) is at least double than input

signal frequency.

2. Displaying the FFT Spectrum

Press the MATH button to display the Math Menu. Use the options to select the

Source channel, Window algorithm, and FFT Zoom factor. You can display only one

FFT spectrum at a time. You can select “Full screen” or “Split” in “ Display” option

3. Select FFT window

Windows reduce spectral leakage in the FFT spectrum. The FFT assumes that the YT

waveform repeats forever. With an integral number of cycles, the YT waveform starts

and ends at the me amplitude and there are no discontinuities in the signal shape A

non-integral number of cycles in the YT waveform causes the signal start and end

points to be at different amplitudes. The transitions between the start and end points

31
cause discontinuities in the signal that introduce high-frequency transients.

According to the tested options and source speciality, make sure the window you

need to use.

5. Measuring an FFT Spectrum Using Cursors

You can take two measurements on FFT spectrums: magnitude (in dB) and frequency

(in Hz). Magnitude is referenced to 0 dB, where 0 dB equals 1 VRMS. You can use

the cursors to take measurements at any zoom factor. (Refer to cursor measure2.11.2)

Use horizontal cursors to measure amplitude and vertical cursors to measure

32
frequency.

If you input a sine signal to channel 1, follow these steps:

1. Measure FFT Amplitude

4) Press the “Source” option button to select “MATH”.

5) Press the “Cur1” option button, turn the “Universal” button to move Cursor 1 to

the highest position of the FFT waveform.

6) The value of Cur1 displaying on the top right of the screen is FFT highest

Frequency. This frequency should be the same as input signal frequency.

Picture 2-22

NOTE：● The FFT of a waveform that has a DC component or offset can

cause incorrect FFT waveform magnitude values. To minimize

the DC component, choose AC Coupling on the source
waveform.
● To display FFT waveforms with a large dynamic range, use the
dBVrms scale. The dBVrms scale displays component
magnitudes using a log scale.
● The Nyquist frequency is the highest frequency that any real-time
digitizing oscilloscope can acquire without aliasing. This
frequency is half that of the sample rate, provided it is within the
analog bandwidth of the oscilloscope. Frequencies above the
Nyquist frequency will be under sampled, which causes aliasing.

2.7.1 Horizontal control knob
You can use the horizontal controls to change the horizontal scale and position

of waveforms. The horizontal position readout shows the time represented by the

center of the screen, using the time of the trigger as zero. Changing the horizontal

scale causes the waveform to expand or contract around the screen center.

■ Horizontal “POSITION” knob

1. Adjust the horizontal position of all channels and math waveforms (the position of

the trigger relative to the center of the screen). The resolution of this control varies

with the time base setting.

2. When you press the horizontal “POSITON” Knob, you can set the horizontal

position to zero.

■“S/div” knob

1. Using to change the horizontal time scale to magnify or compress the waveform. If

waveform acquisition is stopped (using the RUN/STOP or SINGLE button), turn the

S/div knob to expand or compress the waveform.

2. Select the horizontal time/div (scale factor) for the main or the window time base.

When Window Zone is enabled, it changes the width of the window zone by

changing the window time base.

■ Display scan mode：

When the SEC/DIV control is set to100 ms/div or slower and the trigger mode

is set to Auto, the oscilloscope enters the scan acquisition mode. In this mode, the

waveform display updates from left to right. There is no trigger or horizontal position

control of waveforms during scan mode.

2.7.2 Delayed
Use the Window Zone option to define a segment of a waveform to see more

detail. The Window time base setting cannot be set slower than the Main time base

setting.

38
 You can turn the Horizontal Position and SEC/DIV controls to enlarge or minish

waveforms in the Window Zone.

If you want to see a section of the waveform in detail, follow these steps:

(1) Press the “HORI MENU” button to enter the “Horizontal menu”.

(2) Turn the “S/div” knob to change the main timebase scale.

(3) Press the “Delayed” option button to select “On”.

2.8 Trigger System
The trigger determines when the oscilloscope starts to acquire data and display a

waveform. When a trigger is set up properly, the oscilloscope converts unstable

displays or blank screens into meaningful waveforms.

Here are three buttons and one Knob in the Trigger area. Showing as Picture.2-29:

LEVEL knob

Picture 2-29
■ “TRIG MENU” Button: Press the “TRIG MENU” Button to display the “Trigger
Menu”.

■“LEVEL” Knob: The LEVEL knob is to set the corresponding signal voltage of

trigger point in order to sample. Press the “LEVEL” knob can set trigger level to

zero.

■“SET TO 50％” Button: Use the “SET TO 50%” button to stabilize a waveform

quickly. The oscilloscope can set the Trigger Level to be about halfway between the

minimum and maximum voltage levels automatically. This is useful when you

connect a signal to the EXT TRIG BNC and set the trigger source to Ext or Ext/5.

■“FORCE” Button: Use the FORCE button to complete the current waveform

acquisition whether the oscilloscope detects a trigger or not. This is useful for

SINGLE acquisitions and Normal trigger mode.

■ Pretrigger/Delayed trigger: The data before and after trigger the trigger position

is typically set at the horizontal center of the screen, in the full-screen display the

6div data of pretrigger and delayed trigger can be surveyed. More data of pretrigger

and 1s delayed trigger can be surveyed by adjusting the horizontal position.

40
 The feature is very useful because you can see the events that led up the trigger point

everything to the right of the trigger point is called posttrigger information the

amount of delay range (pretrigger and posttrigger information) available is dependent

on the sweep speed selected.

2.8.1 Signal Source

You can use the Trigger Source options to select the signal that the oscilloscope uses

as a trigger. The source can be any signal connected to a channel BNC, to the EXT

TRIG BNC or the AC power line (available only with Edge triggers).

2.8.2 Trigger Type

ADS1000 Series have five trigger types: Edge, Video, Pulse, Slope,

Alternative.

■ Edge Trigger

Use Edge triggering to trigger on the edge of the oscilloscope input signal at the

trigger threshold.

Type Edge With Edge highlighted, the rising or falling edge of
the input signal is used for the trigger.
Source CH1 Triggers on a channel whether or not the waveform
CH2 is displayed.
EXT Does not display the trigger signal; the Ext option
uses the signal connected to the EXT TRIG
front-panel BNC and allows a trigger level range of
-1.2V to +1.2V.
EXT/5 Same as Ext option, but attenuates the signal by a
factor of five, and allows a trigger level range of
+6V to -6V.This extends the trigger level range.
AC Line This selection uses a signal derived from the power
line as the trigger source; trigger coupling is set to
DC and the trigger level to 0 volts.
Slope Trigger on Rising edge of the trigger signal.
Trigger on Falling edge of the trigger signal.

The horizontal position control establishes the time between the trigger position and

the screen center. You can adjust the horizontal “POSITION” knob control to view

waveform data before the trigger, after the trigger, or some of each. When you

change the horizontal position of a waveform, you are changing the time between the

trigger and the center of the display actually. (This appears to move the waveform to

the right or left on the display.)

2.8.5 Slope & Level

The Slope and Level controls help to define the trigger. The Slope option (Edge

trigger type only) determines whether the oscilloscope finds the trigger point on the

rising or the falling edge of a signal.

53
The TRIGGER LEVEL knob controls where on the edge the trigger point occurs.

Note: ● Press the SINGLE button when you want the oscilloscope to
acquire a single waveform.
●. Trigger coupling affects only the signal passed to the trigger
system. It does not affect the bandwidth or coupling of the
signal displayed on the screen.
● Normal Polarity Sync triggers always occur on negative-going
orizontal sync pulses. If the video waveform has positive-going
horizontal sync pulses, use the Inverted Polarity selection.

2.8.6 Trigger Holdoff

You can use the Trigger Holdoff function to produce a stable display of complex
waveforms. Holdoff is time between when the oscilloscope detects one trigger and
when it is ready to detect another. The oscilloscope will not trigger during the holdoff
time. For a pulse train, you can adjust the holdoff time so the oscilloscope triggers
only on the first pulse in the train.

2.9 Acquiring Signals system

Showing as the follow picture，the “ACQUIRE” button for Acquiring Signals system
is at the menu.
Acquire button

Picture 2-40

Table 2-28 The Function manual of Acquiring Signals:

Option Setting Introduction

Acquisition Sampling Use for sampling and accurately display most of
the waveform.
Peak Detect the noise and decrease the possibility of
Check aliasing.
Average Use to reduce random or uncorrelated noise in the
signal display.
Averages
〔4, 16,32
,64,128, Select number of averages.
256〕
Mode Equ time Set the Sampling mode to Equ time.
Real time Set the Sampling mode to Real time.
Sa Rate Display system sampling rate.

When you acquire a signal, the oscilloscope converts it into a digital form and

displays a waveform. The acquisition mode defines how the signal is digitized and

the time base setting affects the time span and level of detail in the acquisition.

■ Sampling: In this acquisition mode, the oscilloscope samples the signal in evenly

spaced intervals to construct the waveform. This mode accurately represents signals

most of the time.

Advantage: You can use this mode to reduce random noise.

56
Disadvantage: This mode does not acquire rapid variations in the signal that may

occur between samples. This can result in aliasing may cause narrow pulses to be

missed. In these cases, you should use the Peak Detect mode to acquire data.

Picture 2-41 Sampling modes

■ Peak Detect: Peak Detect mode capture the maximum and minimum values of a

signal Finds highest and lowest record points over many acquisitions.

Advantage: In this way, the oscilloscope can acquire and display narrow pulses,

which may have otherwise been missed in Sample mode.

Disadvantage: Noise will appear to be higher in this mode.

Picture 2-42 Peak Detect mode

■ Average: The oscilloscope acquires several waveforms, averages them, and

displays the resulting waveform.

Advantage: You can use this mode to reduce random noise.

57
 Picture 2-43 Average mode
■ Equivalent Time Sampling:

The equivalent time sampling mode can achieve up to 20 ps of horizontal resolution

(equivalent to 50GSa/s). This mode is good for observing repetitive waveforms.

■ Real Time Sampling: ADS1000 has the highest Real-time sampling rate

up to 1GSa/s.

■ “RUN/STOP” Button: Press the RUN/STOP button when you want the

oscilloscope to acquire waveforms continuously. Press the button again to stop the

acquisition.

■ “SINGLE” Button: Press the SINGLE button to acquire a single waveform. Each

time you push the SINGLE button, the oscilloscope begins to acquire another

waveform. After the oscilloscope detects a trigger it completes the acquisition and

stops.

When you push the RUN/STOP or SINGLE buttons to start an acquisition, the

oscilloscope goes through the following steps:

1）. Acquire enough data to fill the portion of the waveform record to the left of the

trigger point. This is also called the pretrigger.

2）. Continue to acquire data while waiting for the trigger condition to occur.

3）. Detect the trigger condition.

4）. Continue to acquire data until the waveform record is full.

5）. Display the newly-acquired waveform.

58
■ Base time: The oscilloscope digitizes waveforms by acquiring the value of an

input signal at discrete points. The time base allows you to control how often the

values are digitized.

To adjust the time base to a horizontal scale that suits your purpose, use the S/div

knob.

■ Time Domain Aliasing：

Aliasing occurs when the oscilloscope does not sample the signal fast enough to
construct an accurate waveform record. When this happens, the oscilloscope
displays a waveform with a frequency lower than the actual input waveform, or
triggers and displays an unstable waveform.

2.10.1 X-Y Format

Use the XY format to analyze phase differences, such as those represented by

Lissajous patterns. The format plots the voltage on channel 1 against the voltage on

channel 2, where channel is the horizontal axis and channel 2 is the vertical axis.

The oscilloscope uses the untriggered Sample acquisition mode and displays data as

dots.

XY mode has a breakthrough that trad oscilloscopes restrict sampling rate at

1MSa/s;ADS1000CM series max support 5KSa/s～200MSa/s (1-2.5-5 sequence)

adjusted

Note：The oscilloscope can capture a waveform in normal YT mode

at any sampling rate. You can view the same waveform in XY mode.
To do so, stop the acquisition and change the display format to XY.

64
Operation steps ：

● Channel 1“Volt/div”and vertical “POSITION” set up the horizontal scale

and position.

● Channel 2“Volt/div”and vertical “POSITION” set up the horizontal scale

and position.

● Turn the “S/div” knob to adjust the sampling rate（Range: 5KSa/s～

200MSa/s）.

The following functions are forbidden at XY display form:

● Benchmark wave form and wave mathematic

● Cursor

● Auto（resets display format to YT）

● Trigger Control

● Horizontal Position Knob

● Vector Display Type

● Scan Display

Note：When the display Type is set to Vectors, the oscilloscope

connects the sample points by using digital interpolation.
Interpolation mode contain linearity interpolation and sin(x)/x
interpolation. Sin(x)/x interpolation is suitable for real time mode.
It is effective at 250ns/div or at faster time base in real time mode.

2.11 Measure System

The Oscilloscope displays the voltage in relation to time and test the wave form

displayed. There are scale, Cursor and auto measure modes.

2.11.1 Scale Measurement

This method allows you to make a quick, visual estimate. For example, you

might look at a waveform amplitude and determine that it is a little more than 100

mV. You can take simple measurements by counting the major and minor graticule

divisions involved and multiplying by the scale factor. For example, if you counted

five major vertical graticule divisions between the minimum and maximum values of

a waveform and knew you had a scale factor of 100mV/div, then you could easily

calculate your peak-to-peak voltage as follows:

5 divisions x 100 mV/division = 500 mV.

3.3 Catch the single signal

To capture a single event, you need to gather some pre-test knowledge of the signal in

order to correctly set up the trigger level and slope .if you are not sure the instance of

the signal, you can observe it through auto or normal trigger mode to ensure the

trigger level and slope.

The following steps show you how to use the oscilloscope to capture a single event.

1. Set the Probe option attenuation to 10X and set the switch to 10X on the

probe.

2. Trigger set up：

(1) Press “TRIG MENU” button to show the “Trigger Menu”

(2) Under this menu, set the trigger type to “edge”, Edge type is “Rising”,

source is “CH1”, trigger mode is “Single”, coupling is “DC”

(3) Adjust the horizontal time base and vertical scale to the satisfied range

(4) Turn the “LEVEL” knob to adjust the trigger level

4.2 Troubleshooting

1. After the oscilloscope is powered on，the screen remains dark ，please do as

following steps：

⑴ Check the power cable’s connection.

⑵ Ensure the power switch is turned on.

⑶ After the inspections above，restart the oscilloscope.

⑷ If the oscilloscope is still not used after the checking, please connect with

ATTEN company.

2. If there is no signal wave in the screen after gathering the signal, please do as

following steps:

(1)Check the probe connecting with the signal cable or not

(2)Check the signal cable connecting with the BNC connector or not.

(3)Check the probe whether connect with the goods tested or not.

(4)Check the tested goods produce the signal or not.

(5)Gather the signal again.

3. The value of the tested voltage is 10 times higher/lower than the real one ,

please do as following steps:：

Check the attenuation quotiety whether match the probe attenuation proportion

or not.

4.Display the wave, but not steady , please do as following steps:：

(1) Check the signal source on the trigger interface whether or not match the signal

channel.

(2) Check the trigger mode: normal signal should use the “edge” trigger mode. The

video signal should use the “Video” Trigger mode. The signal would display

steady, only using the matching trigger mode.

(3) Attempt to change the “ coupling” into “HF Reject” or “LF Reject” display, so

that the High/low frequency noise disturb the trigger should be filtrated

5. Press “RUN/STOP” button, but no display.

112
 Check the trigger mode on the trigger interface whether or not in the “normal” or

“single”, and check the trigger level is whether or not over the wave range. If yes,

please put the trigger level to the middle position or set the trigger mode to the

“Auto” position. In another hand, you could choose the “Auto” button to set up

automatically.

6. After the Acquisition is set to Averages or Display Persistence time is set too

long, the waveform refreshes slowly.

It is normal in these settings

7. The signal is displayed as ladder like waveform

(1)This phenomena is normal. The time base maybe is too slow .you should turn

the horizontal SCALE knob to increase horizontal resolution to improve the

display.

(2) Maybe the display Type is set to “Vectors”, You could set it to Dots mode to

improve the display.
