In remote control of the R&S UPP it is essential to wait for the end of a measurement
or sweep before the measured results are fetched and the hardware is newly set.
The following table explains the effect of different combinations of measurement or
sweep triggering in conjunction with a synchronization command.
Table 6-2: Trigger command with/without synchronization
Trigger command with/without
synchronization Description
INIT:CONT OFF;*WAI A single measurement or sweep is triggered. Subsequent com-
mands are processed after the measurement or sweep is comple-
ted.
Generator and analyzer setting commands do not trigger a new
measurement.
A new measurement must be triggered with
INIT;*WAI
.
This command is the simplest to use and should preferably be used
to trigger a measurement.
"INIT:CONT ON;*WAI" A continuous measurement or continuous sweep will be triggered.
Subsequent commands will not be processed until the first mea-
surement or the first sweep cycle has been completed.
Generator and analyzer configuration commands immediately trig-
ger a restart of the continuous measurement.
"INIT:CONT OFF"
without *WAI
When a generator or analyzer setting command is sent during a sin-
gle measurement, i.e. before the measurement is completed, the
measurement is restarted to avoid incorrect results (incorrect
results could be obtained, for instance, if the generator voltage is
varied during the measurement).
Generator or analyzer setting commands sent after the single mea-
surement has been terminated will not trigger a new measurement.
A new measurement must be triggered with "INIT".
"INIT:CONT ON"
without *WAI
Each generator or analyzer setting command restarts a measure-
ment to avoid incorrect measurement results (incorrect results could
be obtained, for instance, if the generator voltage is varied during
the measurement).
6.7 Command Recording
The R&S UPP offers the possibility of recording the equivalent IEC/IEEE bus com-
mands in a separate window during manual control. The recording runs as long as the
window is open. The contents of the window can be edited (also deleted) and copied to
the clipboard.
