Trigger Source 

With this option selected, push-turn the encoder to select how you want to trigger the Zeroscope.

You have five triggering options:

Trg off The scope is untriggered

Trg 1 The scope triggers on the rising edge of the signal at CH 1

Trg 1 The scope triggers on the falling edge of the signal at CH 1

Trg 2 The scope triggers on the rising edge of the signal at CH 2

Trg 2 The scope triggers on the falling edge of the signal at CH 2

Trigger Detection Level 

With this option selected, push-turn the encoder to set the level at which trigger detection occurs.

Trigger threshold can be offset ± 10V (-10000µV - +10000µV). At 0V (the default), a typical bipolar

waveform triggers when it crosses the 0-line. Trigger levels are graphically indicated on the

Zeroscope display.

If you set a trigger threshold beyond the voltage limits of the current waveform, you’ll see a small T?

icon appear in the lower left corner of the display, indicating that it failed to detect a trigger.
