Holdoff

Holdoff:

To use Trigger Holdoff, push the HORIZONTAL Menu button and set the

Holdoff Time option by pressing F4. The Trigger Holdoff function can be used to

generate a stable display of complex waveforms (such as pulse trains). Holdoff is the

time between when the oscilloscope detects one trigger and when it is ready to detect

another. During the holdoff time, the oscilloscope will not trigger. For a pulse train, the

holdoff time can be adjusted to let the oscilloscope trigger only on the first pulse in the

train.

2.9 SAVE/RECALL

Oscilloscope setups, waveforms, Ref, and CSV files can be saved to internal

oscilloscope memory or to a USB storage device. The saved setups, waveforms and

Ref can be recalled from an USB Host interface on the front panel to connect an USB

device for external storage.

The scope supports setups, waveforms, Ref and CSV files storage. The default save

type is setups.

1. Setups

It‘s the default storage type of the scope. It saves the settings of the oscilloscope in

nternal or external memory in “.SET” format. At most 9 setting files (from No.1

～

No.9)

can be stored in internal memory. The stored settings can be recalled.
