Description
Introduction GW Instek AFG-2225
The GW Instek AFG-2225 dual-channel arbitrary function generator brings full-function dual-channel signal generation to test benches, R&D labs, and educational institutions across Bangladesh. Most basic-level generators pair one strong channel with a weaker second channel, but the AFG-2225 equips both channels with identical performance for differential and IQ signaling work. Engineers use it to build Sine, Square, Ramp, Pulse, Noise, and custom arbitrary waveforms, while the 3.5-inch color LCD keeps every setting visible during operation. ASTZBD supplies this generator to teams that need accurate, repeatable signals without paying for a high-end bench instrument.
