GW Instek AFG-2225 software

Remote control and data logging for the GW Instek AFG-2225 waveform generator, on Windows, Linux and macOS - with the same panel BenchMesh uses for every waveform generator.

Awaiting confirmation

Status

Very likely. Support for the GW Instek AFG-2225 was written from GW Instek’s programming manual and follows the same engine as the bench-tested instruments, but nobody has confirmed it on a real AFG-2225 yet. If you own one, connecting it once and reporting the result moves it to Community-confirmed.

Have one on your bench?

Connect it, press Detect, try the controls - then tell us how it went. Every confirmation moves a model from “Awaiting” to “Community-confirmed” for everyone.

Questions

Does BenchMesh work with the GW Instek AFG-2225?
Very likely. Support for the GW Instek AFG-2225 was written from GW Instek’s programming manual and follows the same engine as the bench-tested instruments, but nobody has confirmed it on a real AFG-2225 yet. If you own one, connecting it once and reporting the result moves it to Community-confirmed.
How do I connect the AFG-2225 to my PC?
Over USB-serial / RS-232. 115200 baud, 8N1. Plug in the USB cable (or a USB-RS-232 adapter); BenchMesh finds the port. Then press Detect in BenchMesh: it identifies the waveform generator by its reply and adds it to the bench.
What can I control on the AFG-2225?
Waveform generator: set amplitude, frequency, offset, output, phase, shape, symmetry; read ampl, freq, load, offs, output, phase, shape, symm.
Can I log AFG-2225 measurements to CSV?
Yes. Right-click any reading to add it to a recording; every instrument on the bench is sampled on one shared timeline and exported as one CSV.
Is BenchMesh free?
Yes. BenchMesh is free and open source, for Windows, Linux and macOS, and works offline.
