Acquiring Waveforms
Before you can display, measure, or analyze a waveform, you must acquire it
from a signal. This instrument comes equipped with the features you need for
capturing your waveforms. The following topics provide an overview of captur-
ing signals and digitizing them into waveform records:
H Signal Connection and Scaling: How to connect signals to the instrument
channels; how to offset channels and position and scale the time bases for
acquiring waveforms; how to scale and position waveforms in the display.
H Setting Acquisition Controls: How to choose the appropria te acquisition mode
for acquir ing your wavefor ms; how to star t and stop acquisition.
H Acquisition Control Background: Information describing the data-sampling
and acquisition processes.
H FrameScan Acquisitions: How to use FrameScan acquisition to help analyze
pattern-dependent failures in high bit-rate communications signals.

NOTE. This section describes how the vertical and horizontal controls define the
acquisition of live, channel waveforms. These controls also define how all
waveforms are displayed, both live and derived waveforms (math and reference
waveforms). The following sections cover display-related usage:
H Displaying Waveforms on page 3--53.
H Creating Math Waveforms on page 3--101.
