Acquiring Waveforms
Before you can process a waveform, you must acquire the signal. This
oscilloscope comes equipped with the features you need for capturing your
waveforms before further processing them according to your requirements. The
following sections cover capturing signals and digitizing them into waveform
records:
H
Signal Connection and Conditioning: Connecting waveforms to the
oscilloscope channels; scaling and positioning the channels and time base for
acquiring waveforms.
H
Setting Acquisition Controls: Choosing the appropriate acquisition mode for
acquiring waveforms; starting and stopping acquisition.
H
Acquisition Control Background: Background information on the data
sampling and acquisition process.
H
Using Fast Acquisition Mode: Using Fast Acquisition mode to capture and
display transient events, such as glitches or runt pulses, which are often
missed during the long dead times that are a normal part of digital oscillo-
scope (DSO) operation.
H
Using FastFrame: Using FastFrame to capture many records in a larger
record, and then view and measure each record individually.
Figure 3--1 shows how this process fits into the overall oscilloscope operation.
