1.5.2. Observe the waveform

Press the [Auto Set] button and you should see within a few seconds a square wave of about 5V
peak-to-peak at 1KHz in the display.

1.6. Probe Introduction

1.6.1. Safety

When using the probe, keep your fingers behind the guard on the probe body to avoid electric shock.
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 start any
measurements.

1.6.2. Manual Probe Compensation

Upon the first connection of a probe and an input channel, you should manually perform this
adjustment to match the probe to the input channel. Uncompensated or miscompensated probes may
lead to errors or faults in measurement. To adjust the probe compensation, follow the steps below.
1. Set the Probe option attenuation in the channel menu to 10X. Set the switch on the probe to 10X and
connect the probe to Channel 1 on the oscilloscope. If you use the probe hook-tip, ensure it is firmly
inserted onto the probe. Attach the probe tip to the PROBE COMP ~2V@1KHz connector and the
reference lead to the PROBE COMP Ground connector. Display the channel and then press the Auto
Scale button.
2. Check the shape of the displayed waveform.

Compensated correctly

Overcompensated

Undercompensated

3. If necessary, use a nonmetallic screwdriver to adjust the variable capacity of your probe until the
shape of the waveform turns to be the same as the above figure. Repeat this step as necessary. See the
figure below for the way of adjustment.

1.6.3. Probe Attenuation Setting

Probes are of various attenuation factors which affect the vertical scale of the signal. The Probe Check
function is used to verify if the Probe attenuation option matches the attenuation of the probe.
You can push a vertical menu button (such as the CH1 MENU button) and select the Probe option that
matches the attenuation factor of your probe.
Make sure that the Attenuation switch on the probe matches the Probe option in the oscilloscope.
Switch settings are 1X and 10X.
When the Attenuation switch is set to 1X, the probe limits the bandwidth of the oscilloscope to 6MHz.
To use the full bandwidth of the oscilloscope, be sure to set the switch to 10X.

Saving a Setup: By default, the oscilloscope will save the setup each time before being closed, and
automatically recall the setup once being turned on. (Note: If you modify the setup, please wait for
more than 10 seconds before turning off the oscilloscope to ensure the proper storage of new settings.)
You can save 10 settings permanently in the oscilloscope and reset them as necessary.
Recalling a Setup: The oscilloscope can recall any of your saved setups or the default factory setup.
Default Setup: The oscilloscope is preset for normal operations when it is shipped from the factory. This
is the default setup. You may recall this setup at any time for your requirements.

2.5. Horizontal Controls

Use the horizontal controls to change the horizontal scale and position of waveform. The horizontal
position readout shows the time represented by the center of the screen, using the trigger time as zero.
When you change the horizontal scale, the waveform will expand or contract to the screen center. The
readout near the upper right of the screen shows the current horizontal position in second. The
oscilloscope also has an arrow icon at the top of the graticule to indicate the horizontal position.

Horizontal offset knob

FFT Operation
FFT is used to compute the fast Fourier transform using analog input channels or reference waveform.
FFT takes the digitized time record of the specified source and transforms it to the frequency domain.
When the FFT function is selected, the FFT spectrum is plotted on the oscilloscope display as magnitude
in dBV versus frequency. The readout for the horizontal axis changes from time to frequency (Hertz)
and the vertical readout changes from volts to dB. FFT operation can facilitate the following works:
➢ Measure harmonic components and distortion in the system
➢ Measure the characteristics of the noise in DC power
➢ Analyze vibration
To display FFT waveform:

2.7. Trigger System
The trigger determines when the oscilloscope begins to acquire data and display a waveform. Once a
trigger is properly set up, the oscilloscope can convert unstable displays or blank screens to meaningful
waveform. Here introduce some basic concepts about trigger.
Trigger Source: The trigger can be generated with multiple sources. The most common one is the input
channel (CH1~CH2). Whether the input signal is displayed or not, it can trigger normal operations. Also
the trigger source can be any signal connected to an external trigger channel (only for Edge trigger).
Trigger Mode: You can select the Auto or Normal mode to define how the oscilloscope acquires data
when it does not detect a trigger condition. Auto Mode performs the acquisition freely in absence of
valid trigger. It allows the generation of untriggered waveform with the time base set to 100ms/div or
slower. Normal Mode updates the displayed waveform only when the oscilloscope detects a valid
trigger condition. Before this update, the oscilloscope still displays the old waveform. This mode shall
be used when you want to only view the effectively triggered waveform. In this mode, the oscilloscope
displays waveform only after the first trigger. To perform a single sequence acquisition, push the [Single]
button.
Trigger Position: The horizontal position control establishes the time between the trigger position and
the screen center.
Trigger Level: It sets the amplitude level the signal must cross to cause an acquisition when using the
Edge or Pulse Width trigger.

Trigger Level Knob

Force Trigger: Used to complete an acquisition regardless of an adequate trigger signal. This button
becomes useless if the acquisition is already stopped.
Holdoff: To use Trigger Holdoff, push the Trig Menu button and press Holdoff softkey. The Trigger
Holdoff function can be used to generate a stable display of complex waveform (such as pulse trains).
Holdoff is the time between when the oscilloscope detects one trigger and when it is ready to detect
another. During the holdoff time, the oscilloscope will not trigger. For a pulse train, the holdoff time can
be adjusted to let the oscilloscope trigger only on the first pulse in the train.

condition (data transitioning while the clock is high).
Trigger Condition: Press When softkey to select the desired trigger condition.

➢ Start: trigger when SDA data transitions from high level to low level while SCL is high level.
➢ Stop: trigger when SDA data transitions from low level to high level while SCL is high level.
➢ No Ack: trigger when the SDA data is high level during any acknowledgement of SCL clock position.
➢ Address: the trigger searches for the specified address value. When this event occurs, the
oscilloscope will trigger on the read/write bit.
The AddrBits is "7 bits"; so the range can be from 0 to 0x7F.
➢ Restart: trigger when another start condition occurs before a stop condition.
➢ Address and Data: the trigger searches for the specified address and data value on the data line
(SDA). When this event occurs, the oscilloscope will trigger on the clock line (SCL) transition edge of
the last bit of data. After this trigger condition is selected:
a. Press Data software, use V0 to set the data, refer to 2.7.10;
b. Data Mask: When set to "ON", the data is ignored when it is triggered; the setting is "OFF", and
the data on the data line must be consistent with the data of the index so that it can trigger;
c. Data Index: The range is 0 to 3. It can set four hexadecimal data.
5. Trigger Level: When select SCL channel, press SCL and use Trigger Level knob to modify the trigger
level of the SCL channel. When select SDA channel, use Trigger Level knob to modify the trigger level of

2.10. Measure System

The oscilloscope displays graphs of voltage - time and can help to measure the displayed waveform.
There are several ways to take measurements, using the graticule, the cursors or performing an
automatic measurement.

2.10.1. Scale measurement

Graticule: This method allows you to make a quick, visual estimate and take a simple measurement
through the graticule divisions and the scale factor.
For example, you can take simple measurements by counting the major and minor graticule divisions
involved and multiplying by the scale factor. If you counted 6 major vertical graticule divisions between
the minimum and maximum values of a waveform and knew you had a scale factor of 50mV/division,
you could easily calculate your peak-to-peak voltage as follows:
6 divisions x 50mV/division = 300mV.

2.10.2. Cursor measurement

Cursor: This method allows you to take measurements by moving the cursors. Cursors always appear in
pairs and the displayed readouts are just their measured values. There are two kinds of cursors:
Amplitude Cursor and Time Cursor.
The amplitude cursor appears as a horizontal dotted line, measuring the vertical parameters.
The time cursor appears as a vertical dotted line, measuring the horizontal parameters.
The cursor measurement includes two modes: Manual mode and Tracking mode.
1. Manual mode:
Horizontal cursors or vertical cursors appear in pair to measure time or voltage, and the distance
between the cursors can be manually regulated. The signal source should be set as a waveform to be
measured before the cursors are used.
2. Tracking mode:
A horizontal cursor is intersected with a vertical cursor to form a cross cursor. The cross cursor is
automatically located on the waveform, and the horizontal position of the cross cursor on the
waveform is regulated by selecting “Cur A” or “Cur B” and rotating the [UNIVERSAL] knob. The
coordinates of the cursor point will be displayed on the screen of the oscilloscope.
Push the CURSOR button to display the Cursor Menu.

Moving Cursors: Press the key near Select Cursor to select a cursor and turn Multifunctional Knob to
move it. Cursors can be moved only when the Cursor Menu is displayed.

2.10.3. Automatic Measurement

Automatic Measurement: The oscilloscope performs all the calculations automatically in this mode. As
this measurement uses the waveform record points, it is more precise than the graticule and cursor
measurements. Automatic measurements show the measurement results by readouts which are
periodically updated with the new data acquired by the oscilloscope.
Push the Meas button to perform auto measurements. There are 32 types of measurements and up to
4 can be displayed at a time.
Perform the steps below and select voltage or time parameters to make automatic measurements.

2.12. Acquire

2.12.1. Run Control

Press the [Run/Stop] or [Single] button on the front panel to run or stop the sampling system of the
scope.
When the [Run/Stop] is green, the oscilloscope is running, that is, acquiring data when trigger
conditions are met. To stop acquiring data, press the [Run/Stop] button. When stopped, the last
acquired waveform is displayed.
When the [Run/Stop] button is red, data acquisition is stopped. Red "Stop" is displayed next to the
trademark logo in the status line at the top of the display. To start acquiring data, press [Run/Stop].
To capture and display a single acquisition (whether the oscilloscope is running or stopped), press
[Single] button. The Single run control lets you view single-shot events without subsequent waveform
data overwriting the d isplay.
When [Single] is pressed, the display is cleared, the trigger mode is temporarily set to Normal (to keep
the oscilloscope from auto-triggering immediately), the trigger circuitry is armed, the Single key is
illuminated, and the oscilloscope waits until a user defined trigger condition occurs before it displays a
waveform.
When the oscilloscope triggers, the single acquisition is displayed and the oscilloscope is stopped (the
[Run/Stop] button is illuminated in red). Press [Single] button again to acquire another waveform.
When you acquire an analog signal, the oscilloscope will convert it into a digital one. The real-time
acquisition has four modes: Normal, Peak Detect, Average and High Resolution. The acquisition rate is
affected by the setting of time base.
Normal: In this acquisition mode, the oscilloscope samples the signal in evenly spaced intervals to
establish the waveform. This mode accurately represents signals in most time. However, it does not
acquire rapid variations in the analog signal that may occur between two samples, which can result in
aliasing and may cause narrow pulses to be missed. In such cases, you should use the Peak Detect
mode to acquire data.
Peak Detect: In this acquisition mode, the oscilloscope gets the maximum and minimum values of the
input signal over each sample interval and uses these values to display the waveform. In this way, the
oscilloscope can acquire and display those narrow pulses that may have otherwise been missed in
Normal mode. However, noise will appear to be higher in this mode.
Average: In this acquisition mode, the oscilloscope acquires several waveform, averages them, and
displays the resulting waveform. You can use this mode to reduce random noise.
High Resolution (HR): This mode uses a kind of ultra-sample technique to average the neighboring
points of the sample waveform to reduce the random noise on the input signal and generate much
smoother waveform on the screen. This is generally used when the sample rate of the digital converter
is higher than the storage rate of the acquisition memory.
Note: "Average" and "HR" modes use different averaging methods. The former uses "Multi-sample
Average" and the latter uses "Single Sample Average".
Time Base: The oscilloscope digitizes waveform by acquiring the value of an input signal at discrete
points. The time base helps to control how often the values are digitized. Use the SEC/DIV knob to
adjust the time base to a horizontal scale that suits your purpose.
Push the UTILITY button and press Acquire softkey to set the acquisition parameter.

Options Settings Comments

Normal Acquire and accurately display most waveform.

Mode Peak Detect Detect glitches and eliminate the possibility of aliasing.
(Real Time) Average Reduce random or uncorrelated noise in signal display. The number of
HR averages is selectable.

YT format shows the vertical voltage in relation to time (horizontal

YT
Disp Mode scale); XY format displays a dot between CH1 and CH2 each time when a
XY sample is acquired, where the voltage or current of CH1 determines the
X coordinate of the dot (horizontal) and the voltage or current of CH2
 Roll determines the Y coordinate (vertical). For detailed information, refer to
descriptions on XY format in the following text.

Averages 4, 8, 16, 32, 64, 128 Select the number of averages by pressing F3 or F4.

Memory Depth 4K, 8K, 16K, 4M, 8M The maximum single-channel display is 8M.

2.12.2. XY Mode

The XY mode is used to analyze phase differences, such as those represented by Lissajous patterns. The
format plots the voltage on CH1 against the voltage on CH2, where CH1 is the horizontal axis and CH2 is
the vertical axis. The oscilloscope uses the untriggered Normal acquisition mode and displays data as
dots.
The oscilloscope can acquire waveform in YT mode at any sampling rate. You may view the same
waveform in XY mode. To perform this operation, stop the acquisition and change the display mode to
XY.

2.12.3. Roll Mode

In Roll mode, the waveform display rolls from right to left. No trigger or horizontal offset control of
waveform is available during Roll Mode, and it’s only available when set to 100ms/div or slower.

2.13. Display

2.15.1. AUTO SCALE

Auto Scale is one of the advantages digital oscilloscopes have. When you push the Auto Scale button,
the oscilloscope will identify the type of waveform (sine or square wave) and adjust controls according
to input signals so that it can accurately display the waveform of the input signal.

The Auto Scale function examines all channels for signals and displays corresponding waveform. Auto
Scale determines the trigger source according to the following conditions.
➢ If multiply channels get signals, the oscilloscope will use the channel with the lowest frequency signal
as the trigger source.
➢ If no signals are found, the oscilloscope will use the lowest-numbered channel displayed in Auto Scale
as the trigger source.
➢ If no signals are found and no channels are displayed, the oscilloscope will display and use Channel 1
as the trigger source.
When you use the Auto Scale function and the oscilloscope determines that the signal is similar to a
sine wave, the oscilloscope displays the following options.

4.Troubleshooting
1. If the oscilloscope does not start up at power on, follow these steps:
1)Check the power cord to verify it has been connected properly;
2)Check the power on/off button to ensure it has been pushed;
3)Then restart the oscilloscope.
Contact your local HANTEK distributor or directly keep touch with HANTEK Technical Support
department if the oscilloscope still can not be turned on normally.
2. If there is no display of waveform on the screen when the oscilloscope is turned on, follow these
steps:
1)Check the probe to assure its proper connection to the input BNC;
2)Check the channel switch (CH1~CH2 menu buttons) to make sure it has been turned on;
3)Check the input signal to verify it has been connected to the probe correctly;
4)Affirm that all measured circuits have signals to output;
5)Turn up the magnitude for DC signals with large magnitude;
6)In addition, you may press the Auto Measure button to perform an automatic detection of signals at
first.
Contact HANTEK Technical Support department in time if there is still no display of waveform.
3. If the waveform of the input signal is distorted seriously, follow these steps:
1)Check the probe to assure its proper connection to the channel BNC;
2)Check the probe to assure its good connection to the measured object;
3)Check the probe to verify it has been well calibrated. Otherwise, refer to the content about
calibration described in this manual.
4. If the waveform is rolling continuously on the screen but can not be triggered, follow these steps:
1)Check the trigger source to make sure it consistent with the input channel;
2)Check the trigger level to assure its correct adjustment. You may push the TRIGGER LEVEL knob to
reset the trigger level back to the center of the signal;
3)Check the trigger mode to confirm it is a right choice for the input signal. The default trigger mode is
