and RFB triggers.
The legacy :TRIGger[:SEQuence]:OFFSet command is supported for the VIDeo, LINE, EXT1, and EXT2
triggers.
Initial S/W Revision
Prior to A.02.00
Zero Span Delay Comp 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 allows you to 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.
Key Path
Trigger, External 1
Remote Command
:TRIGger[:SEQuence]:EXTernal1:DELay:COMPensation OFF|ON|0|1
:TRIGger[:SEQuence]:EXTernal1:DELay:COMPensation?
Example
TRIG:EXT1:DEL:COMP ON
Dependencies
No effect except in zero-span, but not locked out in nonzero spans.
Blanked in modes that do not support zero-span measurements. If the SCPI command is sent when
the key is blanked, an error is returned: –221, “Settings conflict; Feature not supported for this
measurement”
In analyzers shipping N9060A, this feature requires N9060A–7FP.
Preset

External 2
Pressing this key, when it is not selected, selects an external input signal as the trigger. A new
sweep/measurement will start when the external trigger condition is met using the external 2 input
connector. The external trigger 2 input connector is on the rear panel.
Pressing this key, when it is already selected, accesses the external 2 trigger setup menu.
Key Path
Trigger
Example
TRIG:SOUR EXT2 Swept SA measurement
TRIG:<meas>:SOUR EXT2 Measurements other than Swept SA
Dependencies
In some models, there is no second External input. In these models, the External 2 key is blanked and
the EXTernal2 parameter will generate a “Hardware missing; Not available for this model number”
message.
Grayed out if in use by Point Trigger in the Source Setup menu.
Forced to Free Run if already selected and Point Trigger is set to External 2.
