Overview of the Device
Micro-Scope is a low-cost oscilloscope design with a
maximum
sample rate of 1 MHz and a time equivalent sample rate
of 5 MHz

How To Use It
plug the parallel-to-serial connector to the device and PC
plug the ac cord to the outlet(Proceed with great cautios,
might get electrocuted)
plug the probe to channel 1 and channel 2
Press the Power button of the device
In PC, Start the Micro-Scope program, and on the main
menu click Configure and then Hardware. The window
pictured below will show up.

PC Interface
Screen Identification
X-Y Mode - Displays voltage on Channel A versus
voltage on Channel B. Channel A is on the X-axis and
Channel B is on the Y- axis.
Frequency Linear Magnitude - Displays the
frequency magnitude versus the frequency (the
program uses a Fast Fourier Transform, FFT,
algorithm to calculate the frequency spectrum).
Magnitude is on the Y-Axis on a linear scale.
Frequency is on the X- Axis.
Frequency Logarithmic Magnitude - Displays the
frequency magnitude versus the frequency (the
program uses a Fast Fourier Transform, FFT,
algorithm to calculate the frequency spectrum).
Magnitude is on the Y-Axis on a logarithmic scale.
Frequency is on the X-Axis.
Waveform Reconstruction Modes
Reconstruction refers to the method of drawing the captured
waveform and spectrum "between the data points".
Oscilloscope Window Modes
V-T Mode - Displays voltage versus time for Channel
A and Channel B. Voltage is on the Y-Axis (using Voltper-division and Channel Offset). Time is on the XAxis.
Triangle - Draw the waveform assuming
reconstruction using triangular pulses. Effectively,
this draws the waveform by drawing a line between
each sample point. This is the best general mode of
waveform reconstruction.

Square - Draw the waveform assuming
reconstruction using square pulses. Effectively, this
draws the waveform in a sample and hold fashion.
This mode quickly reminds the observer of the digital
nature of the data displayed.
Point - Draw only the sample points. Just the facts.
Sinc - Draw the waveform assuming reconstruction
using sinc function pulses. Effectively, this draws the
waveform in as a lowest frequency representation.
You may observe some extra oscillations in
waveforms with sharp corners, etc. Sinc
reconstruction is the most CPU intensive method but
also seems to yield the most accurate representation
of the frequency spectrum plot.
Channel Display Settings and Scaling
Channel enabled - determines whether or not the
channel will be displayed (note it is still captured,
analyzed and saved)
Channel math - Channel A and Channel B are
mathematical manipulations of Channel 1 and
Channel 2. The manipulations are as follows: (1) Ch1
only, (2) Ch2 only, (3) Ch1 + Ch2, and (4) Ch1 - Ch2
Time per Division - Time per horizontal block in V-T
mode. Adjusting the time per division will squeeze or
stretch the waveform along the horizontal axis. The
time per division directly determines the sampling
rate for the selected mode, the number of samples
displayed per channel, and the upper frequency of
the spectrum displays.
Volt per Division - The voltage per vertical block in
V-T mode. The voltage per block in X-Y mode for the
appropriate channel. The volt per division will
squeeze of stretch the waveform along the vertical
axis in V-T mode. It will squeeze or stretch the
waveform along either axis in X-Y mode. It also
dictates the vertical scale of the spectrum
magnitude display.
Channel offset - the channel offset determines
where 0 volts is on the display. This can shift the
waveform up and down in the V-T mode or shift the
position of the waveform in X-Y mode. The channel
offset has no effect on the spectrum displays.
Oscilloscope Capture Modes
Run (Run button) - Continuously polls the
oscilloscope for the next waveform (after a trigger
event). Depending on the Sampling Mode, the
waveform is refreshed every 0.4 or 0.2 seconds. Run
mode only displays the current captured waveform
and no past captured waveforms.
Single (Pause button) - Captures a waveform once
(after a single trigger event) and then stops polling
the oscilloscope. Displays the single captured
waveform on the screen.
Hold (Record button) - Like the Run mode, the hold
mode continuously polls the oscilloscope for the next
waveform. Hold mode displays the current and the
past captured waveforms. The past captured
waveforms are drawn in a slightly darker color.
Currently, resizing the screen or placing other
screens over window will clear the past captured
waveform representations.
