Sets the trigger level to 50% of the
waveform amplitude.
Source
CH1, CH2
Channel 1 or channel 2 input.
Coupling (Edge,
Pulse only)
DC
Sets the coupling to DC.
AC
Sets the coupling to AC.
Slope (Edge only)
Rising
Trigger on rising edge.
Falling
Trigger on falling edge.
Either
Trigger on either rising or falling
edge.
Reject

Holdoff
Sets the holdoff time. The holdoff
time delays triggering the next
waveform for a set amount of time
after triggering.

Positive polarity
Positive polarity (triggered on the
high to low transition)
Negative
polarity
Negative polarity (triggered on the
low to high transition)
Polarity (Video)
Positive polarity
