Oscilloscope Reference Set horizontal delay and horizontal position
Horizontal/Acquisition control window ( Acquisition tab)
From the Horiz /Acq menu, select Horizontal/Acquisition Setup; then open the Acquisition tab.
Overview
Use the Acquisition tab to set the acquisition parameters for all live waveforms. The Acquisition
controls are common to all channels. This means that you cannot acquire in Sample mode on channel
1 while chan
nel 2 acquires in Envelope mode.
For information on the controls, click on the buttons.

Behavior
Acqui
sition is the process of sampling the analog input signal, d igitizing the signal to convert it into
digital data, and then assembling the signal information into a waveform record. The instrument
creates a digital representation of the input signal by sampling the voltage level of the signal at
regular time intervals. The sampled and digitized points are stored in memory along with the
corresponding timing information. The instrument uses the digital representation o f the signal for
display, measurements, or for further p rocessing.
Use the controls on this tab to define the sampling method, the acquisition mode, turn Fast
Acquisitions on or off, and activate an external reference.
