Notes 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.

: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.

Initial S/W Revision A.11.00
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.

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.
