ACQuire:STOPAfter { RUNSTop | SEQuence}
ACQuire:STOPAfter?
Arguments
RUNSTop specifies that the run and stop states should be determined by pressing
the front-panel RUN/STOP button or issuing the ACQuire:STATE comma nd.
SEQuence specifies "single sequence" operation, where the oscilloscope stops
after it has acquired enough waveforms to satisfy the conditions of the acquisition
mode. For example, if the acquisition mode is set to sample, the oscilloscope
stops after digitizing a waveform from a single trigger event. However, if the
acquisition mode is set to average 64 waveforms, then the oscilloscope stops
only after acquiring all 64 waveforms.
The ACQuire:STATE command and the front-panel RUN/STOP button a lso stop
acquisitions when the o scilloscope is in single sequence mode.
Examples
ACQUIRE:STOPAFTER RUNSTOP sets the oscilloscope to stop the acquisition
when you press the front-panel RUN/STOP button.
ACQUIRE:STOPAFTER? might return SEQUENCE.
ALLEv? (Query Only)
Causes the oscilloscope to return all events and their messages, and removes the
returned events from the Event Queue. The messages are s eparated by commas.
Use the *ESR? query to enable the events to be returned. Refer to the Status and
Events section for a complete description of how to use these registers. This
command is similar to repeatedly sending *EVMsg? queries to the oscilloscope .
