completes.
ACTONEVent:NUMACQs
Sets (or queries) the number of acquisitions to complete for the event type
ACQCOMPLete. The default is 1 acquisition.

Arguments
NR1 is an intege
r that specifies the number of events to run. The default
is 1 event and the maximum is 1000000 events. A repeat count greater
than 1000000 specifies to run forever. In this case, the action on event can be
terminated by setting the state for all actions to OFF. When the repeat count is set
to infinite, the query returns 9.9E+37 (IEEE positive infinity).
AFG:AMPLitude
Sets (or qu
eries) the AFG amplitude in volts, peak to peak. The minimum and
maximum allowable settings are dependent upon the output load impedance setting
(AFG:OUTPut:LOAd:IMPEDance) and the selected function (AFG:FUNCtion).
NOTE. The AFG:OUTPut:LOAd:IMPEDance command must be used before
using any of the amplitude/offset/highLevel/lowLevel/Preset commands, so that
saved setups are recalled with the proper load factor applied.
The following values can be set for AFG:AMPLitud e:

The DC function does not use the amplitude setting. The DC level is set using :AFG:OFFSet. Ampltude settings that are set when the :AFG:FUNCtion is DC
are remembered and applied when the function is changed to other than DC.
