1. The instrument starts in the idle state; it enters this state
upon power up, upon receiving most control setting changes,
or upon finishi ng acquisiti on tasks.

Yes
No
2. Control settings are implemented as they are requested.
When you toggle the RUN/STOP control to RUN, the
instrument starts the hardware.
Acquire
pretrigger points
3. The instrument acquires samples until the pretrigger portion
of the waveform record (channel) being acquired is filled.
Trigger

Yes
No
4. The instrument then begins waiting for a trigger. Acquiring
continues to take place, keeping the pretrigger points current,
until triggering criteria are met or a trigger is forced (Auto
trigger mode only) and the instrument accepts a trigger.
Acquire
posttrigger
points
5. The instrument acquires samples until the posttrigger portion
of the waveform record (channel) being acquired is filled.

No
Yes
6. If averaging, enveloping, or waveform database is on, the
record becomes part of the multi-acquisition record that these
modes produce. The process loops back to step 3 above to
acquire additional records until the number of acquisitions
required for the acquisition mode currently set are processed,
and then processing continues to step 7 below.

7. At this point the acquisition record is in DSP memory and is
available to the instrument for measurem ent of its
parameters, display, and so on.
The instrument then checks for a user-specified stop
condition and either returns to its idle state or continues at
step 3, according to what it finds.
