①Firstly, set the oscilloscope to Auto trigger mode (default to Auto trigger mode
after startup), which is used to test periodic signals (PWM belongs to periodic
signals).
②Set the oscilloscope to 1X gear (default to 1X gear after startup).
③Set the oscilloscope to DC coupling mode.
④Insert the probe and move the switch on the probe handle to the 1X position
⑤Ensure that the PWM motherboard has PWM signal output at this time.
⑥Connect the probe clamp to the S pole of the MOS tube and the probe to the
G pole of the MOS tube.
⑦Press the 【 AUTO 】 button once, and the measured PWM waveform will be
displayed. If the waveform after AUTO adjustment is too small or too large,
you can manually adjust the waveform size in zoom mode.
4. Signal generator output measurement
The output voltage of the signal generator is within 30V, and the maximum
test voltage for 1X gear is 80V. Therefore, using 1X gear for testing the signal
generator output is sufficient (both the probe and oscilloscope are set to 1X
①Firstly, set the oscilloscope to Auto trigger mode (default to Auto trigger mode
after startup), which is used to test periodic signals (the signal output by the
signal generator belongs to periodic signals).
②Set the oscilloscope to 1X gear (default to 1X gear after startup).
③Set the oscilloscope to DC coupling mode.
④Insert the probe and move the switch on the probe handle to the 1X position.
⑤Ensure that the signal generator is turned on and working and outputting
signals.
⑥Connect the probe clamp to the black clamp on the output line of the signal
generator, and connect the probe to the red output line of the signal
generator.
⑦Press the [AUTO] button once, and the waveform output by the generator will
be displayed. If the waveform after AUTO adjustment is too small or too large,
you can manually adjust the waveform size in zoom mode.
