Acquiring Waveforms
3-4 CSA8000B & TDS8000B User Manual
Signal Connection and Scaling
This section presents an overview of the instrument features related to setting up
the input signal for digitizing and acquisition. It addresses the following topics:
HWhere to find information for installing sampling modules and connecting
input signals
HHow to turn on channels and adjust their vertical scale, position, and offset
HHow to set the horizontal scale, position, and record length of the Main (time
base) View
NOTE. Terminology: This manual uses the terms vertical acquisition window and
horizontal acquisition window. These terms refer to the vertical and horizontal
range of the acquisition window, which defines the segment of the input signal
that the acquisition system acquires. The terms do not refer to any windows or
display windows on screen. See Conventions on page xii.

Use signal conditioning and scaling controls to ensure the instrument acquires
the data that you want to display, measure, or otherwise process. To ensure the
best possible data for further processing, you do the following:
HSet vertical scale to adjust the waveform size on screen. You can set vertical
offset to shift the vertical acquisition window up or down on the signal to
capture the portion you want.
