①. EXT Trig: External trigger or external trigger/ 5 input
②. Pass/Fail: Pass/Fail detection function output, support Trig_out output
at the same time, AWG1 and AWG2 are arbitrary waveform generator
output.
③. VIDEO Out: VGA video signal output
④. USB device: USB device interface, the oscilloscope can communicate
with the PC through this interface.
⑤. LAN: The oscilloscope can be connected to the local area network for
remote control.
⑥. AC power input socket: AC power input. Use the power cord provided
in the accessories to connect the oscilloscope to the AC power supply
(100 ~ 240V, 45 ~ 440Hz).
⑦. Power switch: When the AC socket is properly connect to the power
supply, turn on this power switch, then press the power on/off on the
front panel to turn on the oscilloscope.
⑧. Safety lock: You can use the safety lock (sold separately) to lock the

1.5 Operation Panel

(1) Vertical Control
① 1 , 2 , 3 , 4 : Analog channel setting keys indicate CH1, CH2, CH3, and
CH4. The four channel labels are identified by different colors also
corresponding to the colors of the waveforms on the screen and the
channel input connectors. Press any key to open the related channel
menu (or activate and close the channel).
② MATH : Press this key to open the mathematical operation menu for add,
subtract, multiply, divide, FFT, logic, and advanced operations.
③ REF : Loads the previously stored reference waveform in the oscilloscope
or the USB disk, you can compare the currently measured waveform with
the reference waveform.
④ Vertical POSITION: Adjust the vertical position of the current channel
waveform, and display the vertical offset value
cursor. Press this knob to return the channel display position back to the
vertical midpoint.
⑤ Vertical SCALE: Adjust the vertical scale of the current channel. Turn
clockwise to reduce in scale and turn counterclockwise to increase in
scale. The waveform display amplitude will increase or decrease during
the adjustment, and the scale information
screen will change in real time. The vertical scale has 1, 2, and 5 steps.
Press the knob allows the vertical scale adjustment to switch between
coarse and fine tuning.
