Speeding up list mode measurements
List mode tests are often used in production lines. The same tests are repeated again
and again for different ATs. Optimizing the test duration is important.
Consider the following rules to minimize the test duration:
●
Reduce the number and size of the segments and the statistical length as far as
possible for your use case.
●
Enable only the results that you need / disable the other result calculations.
●
There are two groups of
FETCh
commands. One for result retrieval per segment
and one for result retrieval over all segments. Which of the two groups is more
effective, depends on the enabled results and on the number of segments. Mini-
mize the number of
FETCh
commands transmitted for result query.
●
To reset the system repeatedly, use partial reset commands instead of the global
reset command
*RST
. Example: Use
SYSTem:RESet 'EVDO Meas1'
to reset
the 1xEV-DO measurement instance 1.
●
To configure the same list mode settings repeatedly, use partial save/recall com-
mands:
–
Configure all list mode settings once.
– Save the list mode settings to a file, for example to the file
ListModeEVDO1.dfl
located in the directory assigned to the
@SAVE
alias:
MMEMory:STORe:ITEM 'EVDO Meas:MEV:LIST',
'@SAVE\ListModeEVDO1.dfl'
– If you want to configure the same settings again, recall the stored settings:
MMEMory:LOAD:ITEM 'EVDO Meas:MEV:LIST',
'@SAVE\ListModeEVDO1.dfl'
