Basic and Advanced Modes

The AFG31000 series is the industry’s first arbitrary function generator

with full function Basic (AFG) and Advanced (Sequence) modes.

In Basic mode, the AFG31000 generates traditional functions and

arbitrary waveforms. The touchscreen and front-panel controls make it

simple to set up.

Basic mode lets you change frequency without the need to worry about

waveform length and sample rate. This feature is useful in analog

designs that characterize filter/amplifier frequency responses or in

digital designs where clock rates change frequently.

keypad, or rotary controls

New with the AFG31000, Advanced mode provides the ability to

generate multiple waveforms with complex timing. In this mode, you

can compose a list (or a sequence) of 1 to 256 waveforms, with total

waveform length up to 16 Mpts/ch (128 Mpts/ch optional) and define the

ouput sequence of these waveforms. Repeat, go-to, wait, jump, and

triggered events are all supported and the large memory provides

space to store many waveforms or long waveforms.

This feature is very useful in applications where many test cases need

to be performed sequentially. Instead of loading the test cases one by

one, you can put all of them in a sequence and load at one time,

switching from one to another seamlessly to greatly improve the test

efficiency.

controls

Additionally, Advanced mode uses variable sample rate technology.

Every sample in a waveform is output once and only once in each

cycle, synchronized to the sample rate. Since there is no skipping or

repetition, all details in the waveforms are kept. This feature is very

useful for applications in which signal fidelity is extremely critical, such

as IQ modulation and pulse train generation.

InstaView™ technology shows the actual

waveform at the DUT

Most waveform generators assume they are driving a 50 Ω impedance.

However, most devices under test do not have a 50 Ω impedance. This

mismatch results in an inconsistency between the waveform as set on

the AFG and the signal at the DUT.
