How to ? Setting acquisition modes
3. Click here (see page 481) for details on setting up the Vertical input controls.
NOTE. Some probes automatically set their termination and other values.
4. Push a front panel channel button (Ch <1– 4>) to select the input signal channel. A channel button
lights when its channel is on.
5. Open the Vertical Setup control window by clicking Vert on the toolbar or selecting the Vertical Setup
command from the Vertical menu. To change the input coupling, select the appropriate Termination
button.
Select DC to couple both the AC and DC components of an input signal.
Select AC to couple only the AC components of an input signal.
Select GND to disconnect the input signal from the acquisition system.
6. Use the Vertical knobs to scale and position the waveform on the screen. Dragging the waveform
handle also positions the waveform.
7. Use the Vertical Setup controls to change the offset. Click in the Offset entry box, and then use the
multipurpose knob to adjust the offset.
8. Use the Horizontal knobs to scale and position the waveform on the screen and to set the record length.
Dragging the reference icon also positions the waveform.
9. Use the Resolution knob to set the record length and sample interval.
10. If you need to stabilize the display, push the trigger Level control to set the trigger level to 50%.
Set
ting acquisition modes
Us
e this procedure to set the data acquisition mode and specify acquisition start/stop methods.
1. Power on the instrument.
2. Set up the horizontal
(see page 177), vertical (see page 481),andtriggering (see page 385) controls.
3. From the Horiz/Acq menu, open the Acquisition control window.
4. Click an Acquisition Mode button. For Average and Envelope modes only, select the number of
acquisitions to average or envelope. For WfmDB acquisition mode, select the number of samples.
5. Push the Run/Stop front-panel button to toggle between starting and stopping acquisitions, or push the
Single button to acquire enough waveforms to satisfy the acquisition mode.
