Superior performance at an affordable price

Most electronic devices, circuits, and systems are designed to handle some

form of a signal. These signals can be simple like an audio frequency or

clock signal or more complex like a serial data stream or the output of an

airbag sensor during a crash. With 20 MHz bandwidth, 14-bit resolution,

and 250 MS/s sample rate, the AFG2021 Arbitrary Function Generator can

create both simple and complex signals at an entry-level price. With

12 standard waveforms, modulation capability, and a built-in noise

generator, you can quickly create the signal you need to thoroughly

exercise your designs.

Intuitive user interface

The innovative ease-of-use features first seen on the AFG3000 Series

arbitrary/function generators are the building blocks for the AFG2021,

providing quick access to setup and operational features. Experienced

AFG3000 users will find it especially easy to set up the new AFG2021. A

3.5 inch color TFT screen shows relevant parameters in both graphic and

text formats, so you can have full confidence in your settings and focus on

the task at hand. The front-panel shortcut buttons and rotary knob provide

quick access to the most frequently used functions and settings.

Excellent frequency agility

Traditional function generators created their output signals using analog

oscillators and signal conditioning. The Tektronix AFG2021 relies on Direct

Digital Synthesis (DDS) techniques. DDS technology synthesizes

waveforms by using a single clock frequency to generate any frequency

within the instrument’s range. DDS architecture provides exceptional

frequency agility, making it possible to program fast frequency and phase

changes, which is useful for testing radio and satellite system components,

amplifiers, and filters.

Frequency range from 1 μHz to 20 MHz, supports a wide range of amplifier

and filter testing applications.

ArbExpress for real-world waveforms with

minimal effort

With ArbExpress software, you can quickly create waveforms that can be

copied to the AFG2021 to meet custom stimulus requirements. ArbExpress

supports direct connection to Tektronix oscilloscopes and AFGs through

USB, GPIB, or LAN. The software allows you to import real-world signals

captured with an oscilloscope onto a PC, then edit and download them onto

an AFG to duplicate the captured waveform. This is extremely useful for

automotive, medical, and industrial applications where recreating sensor

output is critical to analyzing the integrity of the design.

ArbExpress software helps you easily duplicate real-world signals.

Insert productivity with SignalExpress

Every AFG2021 ships with a free copy of the Tektronix Edition of National

Instrument’s LabVIEW SignalExpress software for basic instrument control,

data logging, and analysis. SignalExpress supports the range of Tektronix

bench instruments enabling you to connect your entire test bench. You can

then access each instrument from one intuitive software interface. This

allows you to automate complex measurements requiring multiple

instruments, log data for an extended period of time, time-correlate data

from multiple instruments, and easily capture and analyze your results, all

from your PC. Only Tektronix offers a connected test bench of intelligent

instruments to simplify and speed debug of your complex design.

Connectivity

Using the front-panel USB host port, you can save your customized

waveforms or instrument settings onto a USB memory stick. Reloading the

data is easily done by plugging the device back into the USB host port. The

USB device port and optional GPIB/LAN ports provide multiple alternatives

for connecting the AFG2021 to your PC for waveform download and remote

control.
