Waveform Generators
Waveform Sequencing
Technical Overview
The Agilent 33500 Series waveform generators include A sequence is simply an ordered list of arbitrary waveforms

tions also require the repetition of relatively small arbitrary
waveforms over a large number of cycles, and still other
applications require the arbitrary waveform to interact
with the device under test (DUT) via the instrument's Sync
output. In these situations and many others, sequences of
arbitrary waveforms are the answer.

The software opens a dialog box that allows you to specify
the sequence's target instrument and sampling rate, as
shown in Figure 2.
After you enter the parameters and press OK, you use
a table to list each waveform in the sequence. For each
waveform you can specify the following attributes:
