Setting acquisition modes
Use this procedure to set the data acquisition mode and specify acquisition start/stop methods.
1. Power on the instrument.
2. Set up the horizontal, vertical, and triggering 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.
6. To select the sampling mode, click the Horiz toolbar button, or select the Horizontal/Acquisition Setup command from the
Horiz/Acq menu to open the Horizontal/Acquisition Setup control window.
7. Open the Acquisition tab and select one of the following Sampling Modes:
■
Real Time. This sampling mode acquires all points in a waveform record after one trigger event. RT mode will switch to
ET or IT mode, depending on the time-per-division setting and the number of channels acquiring data.
■
Interpolated. This mode interpolates between the samples the instrument acquires when it cannot acquire all the real
samples it needs to fill up its waveform record.
■
Equivalent. This mode starts when the time base setting (horizontal scale) is too fast to let the instrument get enough
samples with which to create a waveform record using real-time sampling. Equivalent time mode is intended for
repetitive signals only.
Use fast acquisitions
To operate the instrument in Fast Acquisitions mode, set up the horizontal, vertical, and triggering controls, and then follow the
procedure below.
1. Enable Fast Acquisitions mode:
a. In the Horiz/Acq menu, select Horizontal/Acquisition Setup.
b. Open the Acquisition tab.
c. Toggle the Fast Acq button to On, or push the front-panel FastAcq button.
d. Click an option button to optimize the capture of data to suite your measurement.
2. Set up the Display Appearance:
a. In the Display menu, select Display Setup.
b. Open the Appearance tab.
c. Click one of the Style buttons: Vectors, Dots, or Inten Samp. Vectors is the default.
d. For the display Persistence, click either Infinite, Variable, or Off. Off is the default, and erases the screen each time a
new waveform array is displayed. For an explanation of Variable persistence, click here.
e. If you specified Variable, click Time, and adjust the persistence time (decay rate) with the multipurpose knob.
3. Set the Display Readout Options:
a. Open the Display control window Objects tab.
b. Click the Display Date/Time button to toggle the date/time display On or Off.
