5.1 Key Features
The FM stereo radio multi evaluation measurement is programmed as follows:
●
The measurement is controlled by SCPI commands with the following syn-
tax:
...FMSTereo:MEAS:MEValuation...
●
Use general commands of the type
...:FMSTereo:MEAS...
(no
:
MEValuation
mnemonic) to define the signal routing and perform RF and ana-
lyzer settings.
●
After a
*RST
, the measurement is switched off. Use
READ:FMSTereo:MEAS:MEValuation...?
to initiate a single-shot measure-
ment and retrieve the results. You can also start the measurement using
