Trigger command group
Trigger commands control all aspects of instrument triggering.
The three types of triggers are edge, pulse width, and video. Edge triggering is
the default type. Edge triggering lets you acquire a waveform when the signal
passes through a voltage level of your choosing. Pulse width triggering lets you
trigger on normal or aberrant pulses. Video triggering adds the capability of
triggering on video fields and lines.
Table 22: Trigger commands
Command Description
TRIGger on page 222 Forces a trigger event to occur.
TRIGger:A on page 223 Sets the instrument trigger level to 50% of the
minimum and maximum values of the signal.
TRIGger:A:EDGE? on page 224 Returns the trigger coupling, source, and slope
settings for the edge trigger.
TRIGger:A:EDGE:COUPling on page 224 Sets or queries the type of coupling for the edge
trigger.
TRIGger:A:EDGE:SLOpe on page 225 Selects a rising or falling slope for the edge
trigger.
TRIGger:A:EDGE:SOUrce on page 226 Sets or queries the source for the edge trigger.
TRIGger:A:HOLDOff? on page 227 Returns the A trigger holdoff settings.
TRIGger:A:HOLDOff:TIMe on page 227 Sets or queries the instrument trigger holdoff
time.
TRIGger:A:LEVel on page 228 Sets or returns the trigger level for the A trigger.
TRIGger:A:LEVel:CH<x> on page 229 Sets or returns the trigger level for the specified
channel. Each channel can have an
independent level.
TRIGger:A:LOWerthreshold:CH<x> on
page 229
Sets or returns the lower threshold for the
channel selected.
TRIGger:A:MODe on page 230 Sets or queries the trigger mode for the Edge
(all models) and Pulse width trigger types.
TRIGger:A:PULse? on page 231 Returns the current Pulse Trigger settings.

TRIGger:A:PULse:WIDth:POLarity on page 233 Sets or queries the polarity for the pulse trigger.
TRIGger:A:PULSEWidth:SOUrce on page 234 Sets or queries the source for the pulse trigger.
TRIGger:A:PULse:WIDth:WHEN on page 234 Sets or queries the trigger conditions for the
pulse trigger.
TRIGger:A:PULse:WIDth:WIDth on page 235 Sets or queries the width for the pulse trigger.
TRIGger:A:RUNT? on page 236 Returns the current A runt trigger parameters.
TRIGger:A:RUNT:POLarity on page 237 Sets or returns the polarity for the runt trigger.
TRIGger:A:RUNT:SOUrce on page 238 Sets or returns the source for the A runt trigger.
TRIGger:A:RUNT:WHEn on page 238 Sets or returns the type of pulse width the trigger
checks for when it detects a runt.
