Horizontal and acquisition setups Horizontal/Acquisition control window (Acquisition tab)
Overview
Use the Acquisition tab to set the acquisition parameters for all live waveforms. The Acquisition c ontrols
are common to all channels. This means that you cannot acquire in Sample mode on channel 1 while
channel 2 acquires in Envelope mode.

Behavior
Acquisition is the process of sampling the analog input signal, digitizing 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 of the signal for display, measurements, or for further processing.
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.
