●
Use general commands of the type
...:CDMA: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:CDMA:MEAS:OLTR...?
to initiate a single-shot measurement and retrieve
the results. You can also start the measurement using
INIT:CDMA:MEAS:OLTR
and retrieve the results using
FETCh:CDMA:MEAS:OLTR...?
/
FETCh:CDMA:MEAS:RPINterval...?
.

OLTR: Single-Shot Measurement
// *************************************************************************
// Start single-shot measurement for the open loop time response for
// BS power up (resulting in DUT's power down), and return the result
// trace and the limit violation evaluation for the second sequence
// (of the five configured), and also the trace of the reference
// power interval. Query the measurement state (should be "RDY").
// Query measurement state and substates (should be "RUN,ADJ,ACT").
