Adjusting the Holdoff time

You can adjust the Holdoff time to observe complicated waveforms. Holdoff time
means the waiting time for the trigger to be ready for use again. During this time the
oscilloscope will not trigger until the Holdoff is complete.

Follow the normal signal synchronisation procedure and select the edge, trigger
source and inclination in the trigger menu.
•
Adjust the trigger level to make the
waveform display as stable as possible.
•
Press the key in the horizontal MENU to
display the horizontal menu.
•
Adjust the multi-function control in the upper
front panel. The hold-off time will change
accordingly until the waveform display is
stable.
