Hold Off by Time
Sometimes you can achieve a stable display of complex, repetitive waveforms by placing a
condition on the time between each successive trigger event. This time would otherwise be
limited only by the input signal, the coupling, and the instrument's bandwidth. Select a positive or
negative slope, and a minimum time between triggers. The trigger is generated when the
condition is met after the selected holdoff time, counted from the last trigger. Any time between 2
ns and 20 s can be selected. The delay is initialized and started on each trigger.
Edge Trigger with Holdoff by Time. The bold edges on the trigger source indicate that a positive slope has been
selected. The broken upward-pointing arrows indicate potential triggers, which would occur if other conditions
are met. The bold arrows indicate where the triggers actually occur when the holdoff time has been exceeded.
