●
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.
Minimize 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 'LTE Meas1'
to reset the LTE 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
ListModeLTE1.dfl
located in the directory assigned to the
@SAVE
alias:
MMEMory:STORe:ITEM 'LTE Meas:MEV:LIST',
'@SAVE\ListModeLTE1.dfl'
–
If you want to configure the same settings again, recall the stored settings:
MMEMory:LOAD:ITEM 'LTE Meas:MEV:LIST',
'@SAVE\ListModeLTE1.dfl'
