When you send a
MEASure?
query, the R&S NRX performs the following steps:
1. Configures according to the parameter list.
2. Starts a measurement.
3. Returns the result.
Thus, this command combines
CONFigure
and
READ?
. To make more flexible and
accurate measurements, use the
CONFIGure
Example: Measuring average power with one power sensor
You can set the expected power level, resolution and calculation function, and select
the power sensor you want to address, all in one command.
MEAS1? -50,3,(@1)
●
MEAS1
specifies the continuous average measurement
●
-50
optimizes the power sensor settings, if applicable
●
3
specifies resolution setting; 0.01
●
(@1)
specifies the power sensor; connected to port

Querying the parameters transferred previously
MEAS1?
Returns the parameters that were transferred for measurement
1 the last time.

Using CONFigure and READ?
When you send the
CONFigure
commands, the R&S NRX performs step
MEASure?
queries, but does not start the measurement automatically. Thus, you can
change the measurement parameters before making measurements.
For steps
READ?
queries. They compare the parameter
list to the current settings, start a measurement and return the result. If the parameter
list does not match, a SCPI error is returned, and the command is aborted.
