ACQUIRING WAVEFORMS

Choosing Recurrent or Single Acquisition

You can instruct the ScopeMeter test tool to continuously update its display, giving you a dynamic look at waveform activity as it occurs (RECURRENT). You can also tell the test tool to update its display only once, yielding a snapshot record of waveform activity (SINGLE), termed "Single- Shot" elsewhere in this manual.

From the Scope Submenu, press to highlight RECURRENT for continuous display updates. Pressing stops and starts an acquisition. A HOLD on the top right of the display indicates that acquisition is stopped. The time base range is 5ns (10ns)/DIV to 1s/DIV.

Set up the ScopeMeter test tool for "Single-Shot" acquisi- tions with the following procedure:

1.Press to select SINGLE (highlighted).

NO TRIG begins flashing on the display. The instru- ment is waiting for a trigger.

RUN appears on the display when the single acquisi- tion is triggered. HOLD then reappears when acquisi- tion is completed.

2.Now press again and wait for another single acquisition trigger.

The time base range is 100ns/DIV to 1s/DIV.

Roll Mode

Roll mode supplies a visual log of waveform activity and is especially useful when measuring lower frequency

waveforms. To enter the Roll mode, press to select

RECURRENT, then press to select 2s/DIV, 5s/DIV, 10s/DIV, 20s/DIV, or 60s/DIV.

The waveform is now slowly traced on the display from left to right until the full screen is written. Then the trace slowly shifts from right to left like a pen-recorder. The Roll mode is automatically turned off if a time base of 1s/DIV or faster is selected.

Roll is an untriggered mode. The Capture length and Single-Shot functions are not available. However, the

waveform can be frozen on the display by pressing .
