Using a Calculation Function
The following commands combine several setting commands and thus simplify pro-
gramming of the R&S NRX. They use parameter lists that differ for each measurement
type.
●
CONFigure
Configures according to the parameter list, but does not start a measurement.
The query without parameters, for example
CONF?
, returns the parameters trans-
fered the last time. Since the instrument settings can be changed after sensing a
CONFigure
command, the query does not return the current instrument setup.
●
READ
Compares the parameter list to the current settings, starts a measurement and
returns the result. If the parameter list does not match, a SCPI error is returned,
and the command is aborted.
●
MEASure
Configures according to the parameter list, starts a measurement and returns the
result. Thus, this command combines the
CONFigure
and
READ
commands.
The query without parameters, for example
MEAS?
, returns the parameters trans-
fered the last time.
●
FETCh
Returns the last valid measurement result.
