:TRACe[1]|2|3:FSCan:DISPlay ?
FSC:TRAC2:DISP Makes trace 2 visible.
FSC:TRAC:DISP Query display state of trace 1.
This function could have been implemented as an On/Off function, but we wanted to preserve the
legacy "blank" nomenclature. The remote command is implemented as Display on/off.
Whenever you set Update to On for any trace, the Display is set to On for that trace.
1|0|0 (On for Trace 1; Off for 2–3)

[:SENSe]:FSCan:DETector:TRACe[1]|2|3?
:FSC:DET:TRAC2 EAV Set Trace 2 to use EMI Average detector.
:FSC:DET:TRAC3? Query detector type of trace 3.
When Analog Out for Output Config is set to Screen Video/ Demod Audio, only Trace 1 will return the
valid measurement result. Trace 2 & 3 will return –1000dBm if they are turned on.
When a detector selection is made, the menu returns to the previous menu.
The query returns a name that corresponds to the detector type as shown below, and indicates the
setting for Trace 1.

This key is grayed out during multi range scanning. If the grayed out key is pressed, an advisory
message is generated. If the equivalent SCPI command is sent, this same message is generated as
part of a "–221, Settings conflict; Function not available while running multirange scan" warning.
This key is grayed out during final measurement. If the grayed out key is pressed, an advisory
message is generated. If the equivalent SCPI command is sent, this same message is generated as
part of a "–221, Settings conflict" warning.
If an EMI detector (QPD or EMI Average or RMS Average) is already selected for two of the detectors,
then the other EMI detector is grayed out. For example, if Detector 1 is QPD and Detector 2 is EMI
