Comment
Resets the oscilloscope. Wait for the reset to complete
(approximately 3 seconds).
Turns the CH1 waveform on.
Turns the CH2 waveform on.
Turns the CH3 waveform on.
Autosets the displayed waveforms CH1, CH2 and CH3. Wait
for the autoset to complete (approximately 3 seconds).
Specifies that this will be a logic search (a mark will be placed
when all channels transition to the specified state).
Specifies the Boolean logic criteria for channel 1; in this case,
high.
Specifies the Boolean logic criteria for channel 2; in this case,
high.
Specifies the Boolean logic criteria for channel 3; in this case,
high.
Specifies to use 1.4 volts as the threshold for CH1.
Specifies to use 1.5 volts as the threshold for CH2.
Specifies to use 1.3 volts as the threshold for CH3.
Specifies the condition for generating a logic pattern search;
in this case, true.
Specifies the logic operator for the logic search; in this case,
OR.
Turns the search on.
Returns 3 or 4, indicating 3 or 4 times when one of channels
1, 2 or 3 became high.
Note: Depending upon the number of transitions displayed,
you may get 3 or 4 search marks for this example. If you get
3 search marks, try adjusting the horizontal position until you
see 4 search marks.
