Trig 26
Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz 529
Video
Activates the trigger condition that allows the next sweep to start if the detected RF
envelope voltage crosses a level set by the video trigger level. When Video is pressed, a line
appears on the display. The N8201A triggers when the input signal exceeds the trigger level
at the left edge of the display. You can change the trigger level using the key pad or the
scroll keys. The line remains as long as video trigger is the trigger type.
Key Path: Tr ig
Dependencies/Couplings: Trigger Delay adjustment is not available with Video
triggering.
Video triggering is not available when the detector type is Average. Marker Functions that
set the detector to average (such as Marker Noise or Band/Intvl Power) are not available
when the video trigger is on.
This function is not available when the Resolution Bandwidth is less than 1 kHz. If a
Resolution Bandwidth less than 1 kHz is selected while in Video Trigger mode, the Trigger
mode changes to Free Run.
Factory Preset: –25 dBm
Range:
Using logarithmic scale: from 10 display divisions below the reference level, up to the
reference level.
Using linear scale: from 100 dB below the reference level, up to the reference level.
For more information, see“Scale Type" on page 50.
Remote Command:
See “Trig" on page 527 for the command that sets trigger mode. The following commands
set or read the trigger level.
:TRIGger[:SEQuence]:VIDeo:LEVel <ampl>
:TRIGger[:SEQuence]:VIDeo:LEVel?
:TRIGger[:SEQuence]:VIDeo:LEVel:FREQuency <freq> sets the Video
Trigger level when in FM Demod, and Demod View is on
:TRIGger[:SEQuence]:VIDeo:LEVel:FREQuency?
Example:
TRIG:SOUR VID selects video triggering.
