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-SC Arbitrary Function Generator can create both simple and complex signals at an entry-level price. With 9 standard waveforms, 25 built-in application 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-SC, providing quick access to setup and operational features. Experienced AFG3000 users will find it especially easy to set up the new AFG2021-SC. 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-SC 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-SC to meet custom stimulus requirements. ArbExpress supports direct connection to Tektronix oscilloscopes and AFGs through USB, GPIB, or LAN (connection type is model dependent). The software allows you to import real-world signals captured with an oscilloscope onto a PC, then edit and copy them onto an AFG through a USB memory device 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.

Connectivity

Using the front-panel USB host port, you can save your customized waveforms or instrument settings onto a USB memory device. Reloading the data is easily done by plugging the device back into the USB host port.

Compact form factor

The 2U height and half-rack width form factor allow the AFG2021-SC to be stacked on other bench instruments, such as digital multimeters, power supplies, and frequency counters, saving valuable bench space.
