Panning (Acquisition Stopped)
When acquisitions are stopped, the Delay field can be used to control what
portion of acquisition memory will be displayed on screen. Acquisition
memory is comprised of the following sections:
Pre-trigger delay range = delay time setting − (16384 × sample
period)
Post-trigger delay range = delay time setting + (16384 × sample
period)
This shows that one-half of the data stored in acquisition memory was stored
before the delay time setting and one-half of the data in memory was stored
after the delay time setting. Panning allows you to view the entire waveform
record by adjusting the Delay field. Normally, using the delay function to
view all of the acquired waveform (panning) is done on a waveform acquired
in Single (single-shot) mode.
Using the Center Screen field that appears in the Marker Menu (refer to
chapter 5) is another way to shift/pan the display to center it on specific time
markers.
