1300.2519.12 6.751  E-11 
TRIGger Subsystem (WLAN, K91 / K91n) 
The trigger subsystem is used to synchronize device action(s) with events.  
Commands of the TRIGger Subsystem 
– TRIGger[:SEQuence]:HOLDoff 
– TRIGger[:SEQuence]:MODE 
– TRIGger[:SEQuence]:LEVel:POWer 
– TRIGger[:SEQuence]:LEVel:POWer:AUTO 
TRIGger[:SEQuence]:HOLDoff 
 
This command defines the length of the trigger delay. A negative delay time (pretrigger) can be 
set. 
Parameter 
<numeric_value> 
Example 
TRIG:HOLD 500us 
Configures to use a holdoff period of 500 U s after the trigger condition has been met. 
Characteristics 
*RST value: –10 µs
SCPI: Conform 
Mode 
WLAN 
 
TRIGger[:SEQuence]:MODE 
 
This command configures how triggering is to be performed. 
Parameter 
IMMediate  automatically triggers the next measurement at the end of the previous 
measurement. This corresponds to the FREE RUN setting. 
EXTernal  the next measurement is triggered by the signal at the external trigger input 
e.g. a gated trigger 
POWer  triggering of the measurement via signals which are the measurement 
channel. 
 
Example 
TRIG:MODE IMM 
AUTO triggering will occur for the next measurement at the specified video percentage value. 
Characteristics 
*RST value: IMMediate 
SCPI: device–specific
