Remote command:
TRIGger:TYPE on page 261
Source
Selects the trigger source, the channel on which the trigger condition is checked. All
possible channels are listed. You can trigger on any channel to which a signal is con-
nected, even if the channel is not active.
For most trigger types, analog and digital channels can be used as trigger source. Digi-
tal channels require option R&S RTH-B1. For video, runt and slew rate trigger, only
analog channels are available.
Remote command:
TRIGger:SOURce on page 261
Trigger Level
Sets the trigger voltage level.
For the Video/TV trigger, the trigger level is the threshold of the sync pulse. Make sure
that the trigger level crosses the synchronizing pulses of the video signal.
Remote command:
TRIGger:LEVel<m>:VALue on page 262
Holdoff Mode
Selects the method to define the holdoff.
The trigger holdoff defines when the next trigger after the current will be recognized.
Thus, it affects the next trigger to occur after the current one. Holdoff helps to obtain
stable triggering when the oscilloscope is triggering on undesired events.
"Off"
No holdoff
"Time"
Defines the holdoff as a time period. The next trigger occurs only
after the "Time" on page 49 has passed.
"Events"
Defines the holdoff as a number of trigger events. The next trigger
only occurs when this number of events is reached. The number of
triggers to be skipped is defined in "Events" on page 49.
