1.5 General Check
Please check the instrument as following steps after receiving an 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 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 fails 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 press the “AUTOSET“ button into the menu or the
toolbar.
■ Check the shape of the displayed waveform.

f necessary, use a non-metallic tool to adjust the trimmer capacitor of the probe for the
fattest square wave being displayed on the oscilloscope.
2. Repeat if necessary.
WARNNING: To avoid electric shock while using the probe, be sure the perfection of the
insulated cable, and do not touch the metallic portions of the probe head while it is
connected with a voltage source.

USER’S MANUAL 13
1.6 Function Check
Perform this functional check to verify that your oscilloscope is operating correctly
.
■ Connect the oscilloscope
You should connect the A-Type Plug of USB cable to your PC USB port and connect the
other A-Type Plug of USB cable to oscilloscope USB port.
■ Input a signal to a channel of the oscilloscope
The oscilloscope is equipped with two channels plus external trigger.
Please input signal in the following steps:
1. Set the attenuation switch on the probe as 10X and connect the probe on the
oscilloscope with CH1. Aim the slot in the probe connector at the faucet on BNC of CH1
and insert, then, turn right to lock the probe. Finally, attach the tip of probe and ground nip
to the Connector of Probe compensator.
2. Set the CH1 probe attenuation of the oscilloscope to X10. (The default is X1).

USER’S MANUAL 14
3. Attach the tip of probe and ground nip to the Connector of Probe compensator. Click the
button. A square wave will be displayed within a several seconds. (Approximately 1
kHz, 2V, peak- to- peak).
4. Inspect CH2 with the same method. Repeat steps 2 and 3.
1.7 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 5v or more. For accurate calibration,
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.
The self calibration routine takes about several minutes.

he 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. The
oscilloscope continues to acquire enough data so that it can draw the waveform to the
right of the trigger point after it detects a trigger.

3.11 Acquisition Modes
There are two acquisition modes: Normal, Average and Peak Detect.
Normal: In this acquisition mode, the oscilloscope samples the signal in evenly spaced
intervals to construct the waveform.
Average: In this acquisition mode, the oscilloscope acquires several waveforms, averages
them, and displays the resulting waveform. You can use this mode to reduce random noise.
Peak Detect: In this acquisition mode, the oscilloscope finds the maximum and the
minimum in every sampling interval, and use these values to show waveform.

USER’S MANUAL 67
4.2 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 ally
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.
4.3 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. This 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. Click
button.
4. Adjust the vertical scale and offset to display approximately the same amplitude
signals on each channel.
5. Select X-Y format at Horizontal window. The oscilloscope will displays a Lissajous

pattern representing the input and the output characteristics of the circuit.
6. Adjust the scale and offset of the horizontal and vertical to a desirable waveform
display. The following picture shows a typical example.
7. Apply the Ellipse Method to observe the phase difference between the two channels.
Signal in X-Y Format:
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)
θ must be in the range of (0~π/2) or (3π/2~2π) if the main axis of the ellipse is between I
and III quadrant, . If the main axis is at II and IV quadrant, θ must be in the range of (π/2~π)
or (π~3π/2).

X1, X10 two passive probes. The pa
ssive probes have a 6MHz
bandwidth (rated 100Vrms CAT III) when the switch is in the X1
position, and a maximum bandwidth (rated 300Vrms CAT II)
when the switch is in the X10 position. Each probe consists of all
necessary fittings.
A power adapter special for this produ
ct. In addition to the power
adapter shipped with your instrument, you may purchase
another one certified for the country of use.
A USB line, used to connect external devices with USB interface
like a printer or to establish communications betwe
en PC and
the oscilloscope.

Appendix C: General Maintenance
General Care
Do not store or leave the oscilloscope where the device will be exposed to direct sunlight
for long periods of time.
Caution
To avoid damages to the device or probes, do not expose them to sprays, liquids or
solvents.
To avoid damages to the surface of the device or probes not use any abrasive or chemical
cleaning agents.
Cleaning
Inspect the device and probes as often as operating conditions require. Make sure the
device disconnect form all power sources.
To clean the exterior surface, perform the following steps:
1. Remove loose dust on the outside of the oscilloscope and probes with a lint-free cloth.
Use care to avoid scratching the clear glass display filter.
2. Use a soft cloth dampened with water to clean the device.
