Generating Standard Waveforms
Chapter Contents
This chapter shows how to generate standard waveforms (sinusoid, square,
triangle, and ramps) using the Agilent E1445A 13-Bit Arbitrary Function
Generator (called the "AFG").
The following sections show how to generate standard waveforms, how to
setup the AFG for different output loads, how to select the output amplitude
units (for example, V, Vpeak, etc.), and how to set the waveform amplitude
and offset. The sections are as follows:
