Superior Performance at an Affordable Price

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

form of 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.

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

testing applications.

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.
