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.

Key settings are visible at a glance, and are easy to adjust using touch, numeric 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.

Advanced mode lets you build complex waveform sequences with flexible step controls

Sequenced sine waveforms with different frequency and amplitude.

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.

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.
