High Speed Operation
Chapter Contents
This chapter explains how to use the Agilent E1445A Arbitrary Function
Generator at faster speeds and other operations.
Chapter 3 shows how to transfer waveform segments and segment
sequences to the AFG as voltage values and ASCII data, respectively. This
is the slowest method to transfer the lists to the AFG. This chapter shows
faster ways to transfer the lists to the AFG. The sections are as follows:
