Start and stop waveform acquisitions

From the Horiz/Acq menu, select Run/Stop.

Overview

Use the Run/Stop control window to start and stop waveform acquisition.

To use

■

Click Run/Stop to toggle waveform acquisition. (You can also press the front panel Run/Stop button.)

■

Click Single Sequence to complete a single acquisition sequence.

■

Click Force Trigger to immediately start acquiring waveform data without a valid trigger event.

Behavior

These controls operate identically to the front-panel controls.

■

Click Run/Stop once to stop waveform acquisition. The Status readout at the top of the graticule changes from Running to

Stopped and shows the number of acquisitions. Click Run/Stop again to resume waveform acquisition.

■

Click Single Sequence to provide a single sequence of acquisitions each time you click the button. When Single Sequence

is enabled, the front-panel single sequence (Single) button is lighted.

■

In Sample, Peak Detect, or Hi Res acquisition modes, the instrument acquires waveform records with the first valid trigger

event and then stops. In Average or Envelope acquisition modes, the instrument makes the specified number of acquisitions

to complete the averaging or enveloping task.

■

In Waveform Database mode, the instrument acquires and displays a waveform that is the accumulation of several

acquisitions. In addition to time and amplitude, the waveform displays a count of the number of times a specific sample point

has been acquired.

■

When you click Single Sequence (or press the Single button) in Equivalent Time mode, the instrument continues to

recognize trigger events and acquires samples until the waveform record is filled.

■

Click Force Trigger once to acquire a waveform record without a trigger event. Forcing a trigger is useful when the input

signal does not contain a valid trigger. The instrument recognizes and acts upon the forced trigger even when you click the

button before the end of the pretrigger holdoff. The button has no effect when acquisitions are stopped.
