4-24 Programming Guide

COMMAND [:SENSe]:DATA? . . . [<data handle>]

Queries the current measurement result data of the :SENSe subsystem.

Valid <data handles>:

“[SENSe:][XNONE:]FREQuency [1] | 2”

“[SENSe:][XNONE:]POWer [2]”

QUERY RESPONSE • Frequency values are returned in Hz as ASCII bytes in NR1 format.

• Power values are returned in dB in NR2 format.

COMMENTS • Query only.

• Does not initiate any measurement action.

• The data handle is optional. If it is omitted, the query returns values

for all functions enabled by the FUNCtion:ON command.

• Values are returned in the same order as the functions returned by the

FUNCtion:ON? query.

• If this query executes while a measurement is in progress, the prior

measurement result is returned, if the prior result was not invalidated.

COMMAND [:SENSe]:FILTer:FM:AUTO . . . <Boolean>

Turns the Counter’s ability to automatically compensate for frequency

modulation ON or OFF. (*RST: ON)

COMMENTS • When FM:AUTO is ON, the Counter automatically detects FM signals

and modifies its measurement algorithm accordingly.

• Using FM:AUTO increases the time required to compute each

measurement but increases the accuracy of FM signal measurements.
