General Check

Please check the instrument as following steps after receiving the oscilloscope:

Check the shipping container for damage:

Keep the damaged shipping container or cushioning material until the contents of the
shipment have been checked for completeness. Ensure and the instrument has been
checked mechanically and electrically.

Check the accessories:

Accessories supplied with the instrument are listed in "Accessories" in this guide. If the
contents are incomplete or damaged,please notify the franchiser.

Check the instrument:

In case there is any mechanical damage or defect, or the instrument does not operate
properly or fail performance tests, please notify the franchiser.

Probe Compensation

Perform this function to match the characteristics of the probe and the channel input.
This should be performed whenever attaching a probe to any input channel at the first
time.

■ From the “Probe” menu, select attenuation to 1:10. Set the switch to “X10” on the

probe and connect it to CH1 of the oscilloscope. When using the probe hook-tip, insert
the tip onto the probe firmly to ensure a proper connection.

■

Attach the probe tip to the Probe Compensator and the reference lead to the ground

connector, select CH1, and then adjust the timebase and Volt/Div in sidebar.

■

Check the shape of the displayed waveform.

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 you should always run
the routine if the ambient temperature changes by 5
tion, power on the oscilloscope and wait twenty minutes to ensure it is warmed up. To
compensate the signal path, disconnect any probes or cables from the input connectors.
Then, access the “Utility -> Calibration” option and follow the directions on the screen.

Set Edge Trigger

The trigger determines when the oscilloscope starts to acquire data and display a wave­form. When a trigger is set up properly, it can convert unstable displays or blank screens
into meaningful waveforms.
If the oscilloscope wants to acquire a waveform, it collects enough data so that it can
draw the waveform to the left of the trigger point. The oscilloscope continues to acquire
data while waiting for the trigger condition to occur
quire enough data so that it can draw the waveform to the right of the trigger point after it
detects a trigger.

Simple Measurement

User can adjust the controls to meet your measurement to optimize the waveform

display.

To measure the frequency and “Vpp”, you can do these steps as follows:

1. Click the “
display on the bottom of the waveform interface.

2. Click the “Measure->Vertical->Peak-to-Peak” button, the “Vpp” of the signal will also
display on the bottom of the waveform interface.

3. To clear the measurement on the waveform interface, click the “Measure->Clear

Measure” button.

Measure->Horizontal->Frequency” button, the frequency of the signal

Capturing a Single-Shot Signal

To capture a single event, it needs to gather some pre-test knowledge of the signal in
order to set up the trigger level and slope correctly. For example, if the event is derived
from 3.3V COMS logic, a trigger level of 1.2 or higher Volts should work on a rising edge.

Do these steps as follows:

1. Set the probe and the channel attenuations to X 10.

2. Set up the trigger in the Trigger Menu, or in the Trigger Setting window.

1) Adjust the Trigger Mode to Edge.

2) Set the Trigger Sweep to Single.

3) Set the Trigger Source to CH1.

4) Set the Trigger Slope to “+” which means you select the rising edge.

5) Adjust the Volts/DIV and the time base in a proper range for the signal.

6) Drag the trigger level sign on the waveform display screen to proper position. It’s usu­ally higher a little above the normal level.

7) Click START button to start capturing. When the trigger conditions are met, data ap­pears on the display representing the data points that the oscilloscope obtained with one
acquisition.

This function helps to capture the signal occurrence easily, such as the noise with large
amplitude; set the trigger level higher a little above the normal level and press and wait.
When noise occurs, the instrument will record the waveform before and after the trigger.

The Application of the X-Y Operation

X-Y Plot acts to analyze correlation of data of two channels. Lissajous diagram is

displayed in the screen when you use X-Y Plot, which enables to compare frequencies,
amplitudes and phases of counterpart waveform against the reference waveform.
makes it possible to compare and analyze frequency, amplitude and phase between
input and output.

Do these steps as follows:

1. Set the probe attenuation to “x10”. Set the switch to “x10” on the probes.

2. Connect the CH1 probe to the input of the circuit, and connect the CH2 probe to the
output of the circuit.

3. Adjust the vertical scale and offset to display approximately the same amplitude sig­nals on each channel.

4. Select X-Y format at Horizontal window. The oscilloscope will displays a Lissajous pat­tern representing the input and the output characteristics of the circuit.

5. Adjust the scale and offset of the horizontal and vertical to a desirable waveform dis­play. The following picture shows a typical example.

This

6. Apply the Ellipse Method to observe the phase difference between the two channels.

Instruction of the Ellipse Method

Sinθ = A/B or C/D, where θ = phase shift (in degrees) between the two signals.

From the formula above:

θ = ±arcsine (A/B) or ±arcsine (C/D)

If the main axis of the ellipse is between I and III quadrant, θ must be in the range of
(0~π/2) or (3π/2~2π).

If the main axis is at II and IV quadrant, θ must be in the range of (π/2~π) or (π~3π/2).
