8.1.18 Zero Span Delay Compensation On/Off
In Zero Span, there is a natural delay in the signal path, which comes from the RBW
filter. This is usually desirable, as it lets you trigger on events and also see those
events, because the signal is delayed from the trigger event. However, in some
cases it is desirable to eliminate this delay, so that trigger events line up exactly with
the zero-time point in Zero Span. You can use the Zero Span Delay Comp On/Off
feature to enable or disable zero span delay compensation.
Remote Command
:TRIGger[:SEQuence]:EXTernal1|EXTernal2|RFBurst:DELay:COMPensation OFF | ON
| 0 | 1
:TRIGger[:SEQuence]:EXTernal1|EXTernal2|RFBurst:DELay:COMPensation?
Example
:TRIG:EXT1:DEL:COMP ON
:TRIG:EXT1:DEL:COMP?
:TRIG:EXT2:DEL:COMP ON
:TRIG:RFB:DEL:COMP ON
Dependencies No effect except in zero-span, but not locked out in nonzero spans
Zero Span Delay Compensation only appears in the Swept SA and List Power Step measurements.
Only External and RF Burst triggers support it
Does not appear in VXT
If the SCPI command is sent when the control is not shown, an error is returned: -221, “Settings
conflict; Feature not supported for this measurement”
Only appears when External 1|2 or RF Burst is selected as the Trigger, Gate or Periodic Sync Source
Preset
OFF

8.1.19 Select PXI Line
Controls which PXI_TRIG[0..7] backplane line is used for the trigger source.
Only found in modular analyzer products.
