[SENSe]
. :DATA? [<data_handle>]
Query of the most current measured values of active sensor functions.
Measurement values may not be available yet at the moment when this query
is issued, for example. immediately after a receiver setting have been
changed. If this is the case the query will block until the data will become
available. If MEASurement:MODE is CONTinuous this may take up to 200
ms, if PERiodic it may take up to the measurement time
(MEASurement:TIME).
The unit may actively report the end of measurement (MEASuring bit in
operation status register becomes inactive) via SRQ if the status register has
been configured accordingly (see also Section 9).
Remark:
For this command the keyword SENSe must not be omitted as DATA? can be
mixed up with the subsystem TRACe:DATA.
When the scan mode is PSCan, this command returns the error -221
(“Settings conflict”).
Parameters:
none Output of the measured values of all active sensor functions.
<data_handle> see the command SENS:FUNC:ON for the available
functions
Error:
If a requested function is not switched on, or if no functions are switched on,
error -221, "Settings Conflict" is generated.
Result:
The values for the various data-handles are output in the order as specified
under the SENS:FUNC:ON command. The output format (ASCii or block data)
is determined by the command FORMat:DATA. If the output format is block
data, the command FORMat:BORder defines whether the data is output in
big- or little-endian byte order.
data_handle C Data-Type Description
“VOLTage:AC" signed short level in 0.1 dBVV (block data)
level in 1.0 dBVV (ASCii data)
"FREQuency:OFFSet" signed long offset in Hz
“FSTRength" signed short field strength in 0.1 dBVV/m (block
data)
field strength in 1.0 dBVV/m (ASCii
data)
Examples:
SENSe:DATA? -> 23.4, -2500
SENSe:DATA? "VOLT:AC" -> 23.4
SENSe:DATA? "FREQuency:OFFSet" -> -2500
SENSe:DATA? "FSTRength" -> 45.4
