ACQuire:STOPAfter
Tells the digitizing oscilloscope when to stop taking acquisitions. This is
equivalent to setting Stop After in the Acquire menu.
When extended-acquisition-length mode is on, this command can still set and
return values. However, this acquire:stopafter feature will not actually work
while extended-acquisition-length mode is on.

RUNSTop
SEQuence
RUNSTop specifies that the run and stop state should be determined by the user
pressing the front-panel RUN/STOP button.
SEQuence specifies “single sequence” operation, where the digitizing oscillo-
scope 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, and
the horizontal scale is set to a speed that allows real-time operation, then the
digitizing oscilloscope will stop after digitizing a waveform from a single trigger
event. However, if the acquisition mode is set to average 100 waveforms, then
the digitizing oscilloscope will stop only after all 100 waveforms have been
acquired. The ACQuire: STATE command and the front-panel RUN/STOP
button will also stop acquisition when the digitizing oscilloscope is in single
sequence mode.
LIMit specifies the digitizing oscilloscope stops after the limit test condition is
met.
