AFG2021 Arbitrary Waveform/Function Generator Economical Price, Outstanding Performance

Most electronic devices, circuits, and systems are designed to process some form of signal. These signals can be as simple as an audio frequency signal or a clock signal, or as complex as a serial data stream or an airbag sensor output during a crash. With 20 MHz bandwidth, 14-bit resolution, and 250 MS/s sampling rate, the AFG2021 arbitrary function generator can create simple and complex signals at an entry-level price. With 12 standard waveforms, modulation capabilities and a built-in noise generator, you can quickly create the signals you need to fully test your designs.

AFG2021 Arbitrary Waveform/Function Generator Intuitive User Interface

The first new ease-of-use feature you’ll notice on the AFG3000 Series Arbitrary Waveform/Function Generator is the architecture of the AF2021, as it provides quick access to setup and run functions. Veteran AFG3000 users will find the new AFG2021 particularly easy to set up. The 3.5-inch color TFT screen displays relevant parameters in both graphical and text formats, so you can gain complete confidence in your setup and focus on the task at hand. Shortcut buttons and a rotary knob on the front panel provide quick access to frequently used functions and settings.

1 μHz - 20 MHz frequency range supports a variety of amplifier and filter test applications.

AFG2021 Arbitrary Waveform/Function Generator Perfect Frequency Agility

Traditional function generators use an analog oscillator and signal conditioning to create the output signal. Different from this, Tektronix AFG2021 relies on direct signal synthesis (DDS) technology. DDS technology uses a single clock frequency to generate a synthesized waveform at any frequency within the instrument's range. The DDS architecture provides outstanding frequency agility, allowing programming of rapid frequency and phase changes, making it ideal for testing radio and satellite system components, amplifiers and filters.

ArbExpress software helps you easily replicate actual environmental signals.

AFG2021 Arbitrary Waveform/Function Generator ArbExpress® replicates actual environment waveforms with less effort

Through ArbExpress software, you can quickly create waveforms and then transfer the waveforms to the AFG2021 to meet customized stimulus requirements. ArbExpress supports direct connection to Tektronix oscilloscopes and AFG via USB, GPIB or LAN. Through this software, you can import the actual environmental signals captured by the oscilloscope into your PC, then edit the signals, download the signals to the AFG, and reproduce the captured waveforms. This is particularly suitable for applications such as automotive, medical, and industrial where reconstructing sensor output is critical to analyzing the integrity of the design.

AFG2021 arbitrary waveform/function generator SignalExpress improves work efficiency

Each AFG2021 comes standard with free Tektronix version of National Instrument LabVIEW SignalExpress software, which supports basic instrument control, data recording and analysis. SignalExpress supports a variety of Tektronix benchtop instruments and can connect the entire test platform. You can then access each instrument from an intuitive software interface, automate complex measurements requiring multiple instruments, record data over longer periods of time, time-correlate data from multiple instruments, easily capture and Analyze measurements and do it all from your PC. Only Tektronix provides a connectivity test platform composed of multiple intelligent instruments to simplify and speed up the debugging process of complex designs.

AFG2021 Arbitrary Waveform/Function Generator Connectivity

By using the USB host port on the front panel, you can save customized waveforms or instrument settings to a USB flash drive. You can easily reload data by simply plugging the USB flash drive back into the USB host port. The USB device port and the optional GPIB/LAN port provide a variety of connection methods. You can connect the AFG2021 to a PC, download waveforms, and control it remotely.

AFG2021 arbitrary waveform/function generator compact form factor

The 2U height and half-rack width form factor allows the AFG2021 to be stacked on top of other desktop instruments, such as digital multimeters, power supplies, and frequency counters, saving valuable bench space. With the optional RMU2U rack mounting kit, GPIB interface and full support for SCPI, AFG2021 provides a perfect solution for automatic test systems.
