Multi Evaluation: Specifying Measurement-Specific Settings
The CDMA2000 multi evaluation measurement is programmed as follows:
●
The measurement is controlled by SCPI commands with the following syn-
tax:
...CDMA:MEAS:MEValuation...
.
●
Use general commands of the type
...:CDMA:MEAS...
(no
:MEValuation
/
no
:OLTR
mnemonic) to define the signal routing and perform RF and analyzer
settings.
●
After a
*RST
, the measurement is switched off. Use
READ:CDMA:MEAS:MEValuation...?
to initiate a single-shot measurement and
retrieve the results. You can also start the measurement using
INIT:CDMA:MEAS:MEValuation
and retrieve the results using
FETCh:CDMA:MEAS:MEValuation...?
.
