Tektronix Dual-Channel Function Generator 25 MHz Max FM Modulation AFG31022

Tektronix AFG31022 function generator is a high-performance arbitrary function generator designed for laboratory, industrial, and educational use. Featuring two output channels, it covers a maximum sinewave frequency range of 25 MHz and supports FM modulation for complex signal testing. The instrument includes a 9-inch capacitive touch screen with a modern, smartphone-like interface offering pinch, zoom, and scroll gestures to enhance user interaction and parameter setup efficiency.

This function generator employs patented InstaView™ technology, enabling engineers to visualize actual waveforms on devices under test without an oscilloscope or probes, removing uncertainty caused by impedance mismatches. Its comprehensive waveform generation capabilities include sine, square, triangle, sawtooth, and arbitrary waveforms with a 14-bit vertical resolution for excellent signal fidelity.

Designed with robust features such as output amplitude from 1 mVpp to 10 Vpp, 50 Ω output impedance, and a CMOS output level of 2 to 20 V Pk-Pk, the AFG31022 supports advanced modulation including FM, amplitude modulation (internal and external), and digital frequency control. The device offers internal linear and logarithmic sweep functions along with a sequencing option allowing programming of up to 256 waveform steps for complex test scenarios. Protection circuits prevent damage from overvoltage and overcurrent conditions.

The built-in ArbBuilder application permits users to create and modify arbitrary waveforms directly on the instrument, eliminating the need for a PC connection. Additionally, the generator includes a Double Pulse Test feature to generate pulses with varying widths for device characterization. The instrument is suitable for industrial testing, research laboratories, educational institutions, and manufacturing test environments.

The device dimensions are 412.8 mm (length) × 143.3 mm (width) × 191.8 mm (height), with a weight of approximately 4.7 kg. Operating temperature ranges from 0°C to 50°C. It complies with RoHS standards ensuring environmentally safe materials.

The two output channels provide flexible and independent waveform generation. The capacitive touch screen enhances user interface responsiveness. InstaView™ technology simplifies waveform verification on the device under test.

Sequencing capability supports complex waveform programming with up to 256 steps. ArbBuilder feature enables waveform creation and editing on instrument. Robust protections reduce risk of instrument damage. Double Pulse Test application facilitates efficient device testing.

High vertical resolution ensures low distortion signals. Supports multiple modulation modes including FM and amplitude modulation. Compact size and moderate weight favor portability in lab settings.
