Programmer’s Guide 105
Video Trigger Level Amplitude
:TRIGger[:SEQuence]:VIDeo:LEVel <value>
:TRIGger[:SEQuence]:VIDeo:LEVel?
Specifies the level at which a video trigger will occur. Video is adjusted
using this command, but must also be selected using the command
:TRIGger[:SEQuence]:SOURce VIDeo.
Range: 10 display divisions below reference level to reference level
Default Unit: current amplitude units
Example: :TRIGger:VIDeo:LEVel -20 dBm
Key access: Shift > Sweep > Trigger > Video >Video Level
External Trigger Slope
:TRIGger[:SEQuence]:EXTernal:SLOPe POSitive|NEGative
:TRIGger[:SEQuence]:EXTernal:SLOPe?
This command activates the trigger condition that allows the next sweep
to start when the external voltage (connected to EXT TRIG IN connector)
passes through approximately 1.5 volts. The external trigger signal must
be a 0 V to +5 V TTL signal. This function only controls the trigger
polarity (for positive or negative-going signals).
Before you set the trigger slope, The external trigger source must be
selected using the command :TRIGger[:SEQuence]:SOURce
EXTernal.
*RST: Positive
Key access: Shift > Sweep > Trigger > Trigger Slop
RF Burst Level
:TRIGger[:SEQuence]:RFBurst:LEVel <value>
:TRIGger[:SEQuence]:RFBurst:LEVel?
Specifies the level at which a RF burst trigger will occur. Before you set
the RF burst trigger level, the RF burst trigger must be selected using
the command :TRIGger[:SEQuence]:SOURce RFBurst.
Example: :TRIGger:RFBurst:LEVel -30
Key access: Shift > Sweep > Trigger > RFBurst > RFBurst Level
