2.8.5 Slope & Level

The Slope and Level controls help to define the trigger. The Slope option (Edge trigger

type only) determines whether the oscilloscope finds the trigger point on the rising or the

falling edge of a signal.

The TRIGGER LEVEL knob controls where on the edge the trigger point occurs

2.8.6 Trigger Holdoff

You can use the Trigger Holdoff function to produce a stable display of complex

waveforms. Holdoff is time between when the oscilloscope detects one trigger and when

it is ready to detect another. The oscilloscope will not trigger during the holdoff time. For

a pulse train, you can adjust the holdoff time so the oscilloscope triggers only on the first

pulse in the train.

Note:

● Press the SINGLE button when you want the oscilloscope to

acquire a single waveform.

●. Trigger coupling affects only the signal passed to the trigger

system. It does not affect the bandwidth or coupling of the

signal displayed on the screen.

● Normal Polarity Sync triggers always occur on negative-going

horizontal sync pulses. If the video waveform has positive-going

horizontal sync pulses, use the Inverted Polarity selection.
