5. Push the Set Horizontal Position to 0s side-menu button to return the trigger point to the center of the waveform record

(setting delay to 0). Pushing this button does not turn off the delay mode.

You can also pu

sh the front-panel Horizontal Position knob to return the trigger point to the center of the w aveform record.

Trigger Delay is different than Trigger Holdoff. (See page 29, Holdoff trigger mode.)

Setting the r

ecord length

Use this procedure to set the record length. The record length sets how many samples (data points) are added to a waveform

record. Available record lengths are 2000; 20,000; 200,000; 2 m illion (2M); and 20 million (20M) points.

NOTE. 20M waveforms c annot be loaded into reference memory, either directly from the oscilloscope or from a saved ﬁle.

All other record length waveforms can be loaded into reference memory.

1. Push Acquire.

2. Push the

Record Length side-menu button.

3. Use the Multipurpose knob to select and set the record length.

Use longer record lengths to either capture

more sa

mples for a w aveform record, or

capture more c ycles of a waveform, then

use the Zoom controls to investigate the

wavefo

rm in more detail.
