Condition: New Other — not in original packaging, like new, supplied as pictured.

The GW Instek AFG-2225 is a dual-channel arbitrary function generator offering 25 MHz frequency bandwidth with 1 µHz resolution and 10 Vpp output amplitude on both channels. Both channels share identical characteristics, making this instrument well suited to differential and IQ signalling applications. Built-in waveforms include Sine, Square, Ramp (Triangle) and Noise, with a 1%–99% adjustable duty cycle on the Square waveform for use as a pulse source. The 66 built-in arbitrary waveforms can be edited or entirely new waveforms created. Modulation modes include AM, FM, PM, FSK and SUM, alongside Sweep, Burst and Frequency Counter functions. A 3.5-inch colour LCD provides clear waveform and parameter display, and USB Host/Device interfaces allow direct connection to a PC or compatible GW Instek GDS-series oscilloscopes for waveform capture and reconstruction.

GW Instek AFG-2225 — Dual-Channel Arbitrary Function Generator

The GW Instek AFG-2225 is a basic-level dual-channel arbitrary function generator that delivers superior features for its class. Both channels are equipped with identical characteristics to support dual-signal applications such as differential or IQ signalling. Its outstanding cost-to-performance ratio makes it a practical instrument for accelerating the development process across education, R&D, and production environments.

The AFG-2225 features AM, FM, PM, FSK and SUM modulation, Sweep, Burst and Frequency Counter functions applicable to a wide range of communication fields. Its intuitive interface and 3.5-inch colour LCD display comprehensive operation information including the true waveform at the output. USB Host and Device interfaces allow the instrument to link with PCs and GW Instek GDS-series Digital Storage Oscilloscopes, enabling captured waveforms to be reconstructed and replayed. Arbitrary waveforms can be created using the PC software and transferred via USB flash drive.
