The following sections provide programming examples for the TD-SCDMA multi evalu-
ation measurement.
The examples have been tested with the aid of a simple software tool.

5.1 General Examples
The TD-SCDMA multi evaluation measurement is programmed as follows:
●
The measurement is controlled by SCPI commands with the following syn-
tax:
...TDSCdma:MEAS:MEValuation...
●
Use general commands of the type
...:TDSCdma:MEAS...
(no
:MEValuation
mnemonic) to define the signal routing and perform RF and analyzer settings.
●
Use general commands of the type
...:TDSCdma:MEAS:UESignal...
(no
:MEValuation
mnemonic) to inform the R&S
CMW about the basic properties
of the measured TD-SCDMA signal.
●
After a
*RST
, the measurement is switched off. Use
READ:TDSCdma:MEAS:MEValuation...?
to initiate a single-shot measurement
and retrieve the results. You can also start the measurement using
INIT:TDSCdma:MEAS:MEValuation
and retrieve the results using
FETCh:TDSCdma:MEAS:MEValuation...?
.
●
For synchronization and proper decoding, some UE signal settings must be in
accordance with the measured signal; see
