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
