power on), Auto trigger mode is used to test the periodic signal (PWM belongs to
periodic signal)
2: The oscilloscope is set to the 1X position (the default is 1X position after booting)
3: The oscilloscope is set to DC coupling mode
4: Plug in the probe and turn the switch on the probe handle to the 1X position
5: Make sure that the PWM motherboard has a PWM signal output at this time
6: Connect the probe clip to the S pole of the MOS tube and the probe to the G pole
of the MOS tube
7: Press the [AUTOSET] button once, the measured PWM waveform is displayed. If the
waveform after the automatic adjustment is too small or too large, you can press
[CTRL] to switch to the zoom button bar, press [V+] and [V-] Manually adjust the
waveform size
Signal generator output measurement
Gear selection: The output voltage of the signal generator is within 30V, and the
maximum test of 1V is 40V, so it is sufficient to test the output of the signal generator
with 1X (the probe and oscilloscope are set to 1X).
1: First set the oscilloscope to Auto trigger mode (default is Auto trigger mode after
power on), Auto trigger mode is used to test the periodic signal (the signal output by
the signal generator belongs to the periodic signal)
2: The oscilloscope is set to the 1X position (the default is 1X position after booting)
3: The oscilloscope is set to DC coupling mode
4: Plug in the probe and turn the switch on the probe handle to the 1X position
5: Make sure the signal generator is turned on and outputting signals
6: Connect the probe clip to the black clip of the signal generator output cable, and
connect the probe to the red output cable of the signal generator
7: Press the [AUTOSET] button once, and the waveform output by the generator is
displayed. If the waveform after the automatic adjustment is too small or too large,
you can press [CTRL] to switch to the zoom button bar, press [V+] and [V-] Manually
adjust the waveform size
220V or 110V household mains measurement
Gear selection: household electricity is generally 180 — 260V, peak-to-peak voltage is
507 = 733V, 1X file can measure up to 40V, 10X file can measure up to 400V, 100X file
can measure up to 4000V, the default standard probe is 10X high voltage probe, the
highest can only be Measure 400V peak-to-peak, so you need to prepare your own
100X probe, and then set it to 100X, that is, the probe and oscilloscope must be
switched to 100X.
1: First set the oscilloscope to Auto trigger mode (default is Auto trigger mode after
power on), Auto trigger mode is used to test the periodic signal (5OHz of household
electricity is a periodic signal)
2: The oscilloscope is set to the 100X position (the default is 1X position after booting)
3: The oscilloscope is set to AC coupling mode
