OLTR: Specifying Measurement-Specific Settings
The 1xEV-DO OLTR measurement is programmed as follows:
●
The measurement is controlled by SCPI commands with the following syn-
tax:
...EVDO:MEAS:OLTR...
.
●
Use general commands of the type
...:EVDO:MEAS...
to define the signal rout-
ing and perform RF and analyzer settings.
●
Trigger setting commands are the same as by the multi evaluation measurement,
see
Configuring the Trigger System
●
After a
*RST
, the measurement is switched off. Use
READ:EVDO:MEAS:OLTR...?
to initiate a single-shot measurement and retrieve
the results. You can also start the measurement using
INIT:EVDO:MEAS:OLTR
and retrieve the results using
FETCh:EVDO:MEAS:OLTR...?
/
FETCh:EVDO:MEAS:RPINterval...?
.
