If you need to compare several single-shot events,
press
Autostore
.
Like the
Run
key,
Autostore
also arms the trigger circuit. When
the trigger conditions are met, the oscilloscope triggers. Pressing
Autostore
again rearms the trigger circuit, but this time the display
is not erased. All the data points are retained on the display in half
bright with each trigger allowing you to easily compare a series of
single-shot events.
After you have acquired a single-shot event, pressing a front-panel key,
softkey, or changing a knob can erase the event from the display. If you
press
Stop
, the oscilloscope will recover the event and restore the
oscilloscope settings.

To exit the Autostore mode, press either
Run

Autostore
. Notice that RUN replaces STORE in the status line,
indicating that the oscilloscope has exited the Autostore mode.
Operating hint
The single-shot bandwidth is 2 MHz for single-channel operation, and 1 MHz for
two-channel operation. There are twice as many sample points per waveform
on the one-channel acquisition than on the two-channel acquisition. On the
HP 54600B and HP 54603B, channels 1 and 2 are captured simultaneously. On
the HP 54601B and HP 54602B channels 1 and 2 are captured simultaneously,
then on the next trigger channels 3 and 4 are captured simultaneously.
