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").

3.4.2 Using 1xEV-DO List Mode
The 1xEV-DO multi evaluation measurement is programmed as follows:
●
The measurement is controlled by SCPI commands with the following syn-
tax:
...EVDO:MEAS:MEValuation:LIST...
●
Use general commands of the type
...:EVDO: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 and list mode is disabled. Use
CONFigure:EVDO:MEAS:MEValuation:LIST ON
to enable the list mode and
INIT:EVDO:MEAS:MEValuation
to initiate a single-shot measurement.
●
Use
FETCh:EVDO:MEAS:MEValuation:LIST:...?
commands to retrieve the
results.
