Digital Storage Oscilloscope 25
Before this update, the oscilloscope still displays the old waveforms. This mode shall
be used when you want to only view the effectively triggered wveforms. In this mode,
the oscilloscope displays waveforms only after the first trigger. To perform a single
sequence acquisition, push the [Single] button.
Trigger Position: The horizontal position control establishes the time between the
trigger position and the screen center.
Trigger Level: It sets the amplitude level the signal must cross to cause an acquisition
when using the Edge or Pulse Width trigger.
Force Trigger: Used to complete an acquisition regardless of an adequate trigger
signal. This button becomes useless if the acquisition is already stopped.
Holdoff: To use Trigger Holdoff, push the Trig Menu button and press Holdoff softkey.
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.
