The Waveform Menu; Sec/Div Field; Accumulate Field; Delay Field - HP 1660CP Series User Manual

The Waveform Menu

sec/Div field

When acquisition control is set to automatic, the sec/Div field affects the
sample period. Timing waveforms are reconstructed relative to the sample
period. A shorter sample period puts more sample points on the waveform
for a more accurate reconstruction but also fills memory more quickly.
If the sec/Div is changed resulting in a change in the next sample period, you
must run the analyzer again before the current sample period display is
updated. The sample period is shown in the second row from the top when
the markers are turned off.

Accumulate field

The Accumulate field controls whether old data is cleared or displayed along
with new data. The Accumulate field will toggle On/Off. When Accumulate is
on, the analyzer displays the data from a current acquisition on top of the
previously acquired data. When Accumulate is off, the display is cleared
before each new run cycle.
If you leave the Waveform menu, or pop up a menu over the waveform
display, any accumulated display data is lost and the accumulation process
starts over.

Delay field

Depending on the analyzer configuration, a positive or negative delay
measured in either states (State only) or time (Timing only) can be set. The
Delay field lets you scroll the data and place the display window at center
screen. Changing the delay will not affect the data acquisition unless it is a
timing analyzer and the acquisition mode is automatic. In this case, the
sample period changes.
