11 Occupied Bandwidth Measurement
Sweep/Control
had ONLY relative burst triggering
Initial S/W Revision
Prior to A.02.00
Modified at S/W Revision
A.04.00
Trigger Slope
It is set positive to trigger on a rising edge and negative to trigger on a falling edge.
Key Path
Trigger, RF Burst
Remote Command
:TRIGger[:SEQuence]:RFBurst:SLOPe POSitive|NEGative
:TRIGger[:SEQuence]:RFBurst:SLOPe?
Example
TRIG:RFB:SLOP NEG
Couplings
This same slope is used in the RF Burst selection for the trigger source in the Trigger menu and for
the period timer sync source (in the Trigger menu and in the Gate Source menu).
Preset
POSitive
State Saved
Saved in instrument state
Backwards
Compatibility SCPI
:TRIGger[:SEQuence]:FRAMe:RFBurst:SLOPe
Backwards Compatibility
Notes
The legacy :TRIGger[:SEQuence]:SLOPe command affects the slopes for the VID, LINE, EXT1, EXT2,
and RFB triggers.

Periodic Timer (Frame Trigger)
Pressing this key, when it is not selected, selects the internal periodic timer signal as the trigger. Triggering
occurrences are set by the Period parameter, which is modified by the Sync Source and Offset. Pressing
this key, when it is already selected, accesses the periodic timer trigger setup functions.
If you do not have a sync source selected (it is Off), then the internal timer will not be synchronized with any
external timing events.
Key Path
Trigger
Example
TRIG:SOUR FRAM Swept SA measurement
TRIG:<meas>:SOUR FRAM Measurements other than Swept SA
State Saved
Saved in instrument state
Readback
[Sync: <value of Sync Source>], for example, [Sync: External 1]
Status Bits/OPC
dependencies
The Status Operation Register bit 5 "Waiting for Trigger" is set at the same time as the Sweeping or
Measuring bit is set. It is cleared when the trigger actually occurs (that is, after the trigger event
occurs and all the applicable trigger criteria have been met). A corresponding pop-up message
("Waiting for trigger") is generated if no trigger signal appears after approximately 2 sec. This
message goes away when a trigger signal appears.
