The GW Instek AFG-4000 Series is a family of arbitrary function generators spanning 25 MHz to 250 MHz of bandwidth, offered in both single-channel (AFG-4125E, AFG-4125AE) and dual-channel configurations (AFG-4225E, AFG-4235, AFG-4260, AFG-4280, AFG-4210H, AFG-4225H). Every model in the series provides 1 µHz frequency resolution across its full bandwidth, with built-in standard waveforms including sine, square, triangle, ramp, pulse, noise, harmonic, and arbitrary waves, plus a comprehensive modulation library.

The series is positioned by the datasheet for educational institutions, automotive electronics, and electronic products and parts development. The integrated modulation set — AM, DSB-AM, FM, PM, PWM, ASK, PSK, BPSK, QPSK, FSK, 3FSK, 4FSK, OSK, and SUM — combined with sweep, burst, and counter functions makes the AFG-4000 Series a flexible stimulus source for stimulus-response benches, classroom signal-generation curricula, and component-level automotive electronics test.

Brand Heritage

GW Instek is the test and measurement brand of Good Will Instrument Co., Ltd., a Taiwan-based instrument manufacturer founded in 1975 and headquartered in New Taipei City. The company has operated continuously under the GW Instek brand and has not undergone the kind of corporate-name evolution seen with brands such as HP/Agilent/Keysight.

Compare Other Models in This Series

The AFG-4000 Series is structured as a tiered arbitrary function generator family covering bandwidths from 25 MHz to 250 MHz. The datasheet defines a clear three-tier architecture: entry-level 25 MHz models (AFG-4125E, AFG-4125AE, AFG-4225E) at 125 MSa/s and 14-bit resolution; mid-range 35 MHz to 100 MHz models (AFG-4235, AFG-4260, AFG-4280, AFG-4210H) at 500 MSa/s and 16-bit resolution; and the flagship AFG-4225H at 250 MHz, 1.25 GSa/s, and 16-bit resolution.

Beyond raw bandwidth, the family is differentiated by channel count, arbitrary waveform memory depth, communication interfaces, and touch screen support. All members of the family share the same 1 µHz frequency resolution, the same 8-inch TFT display platform, and the same built-in modulation, sweep, burst, and counter functions documented in the datasheet.

Each new AFG-4000 Series model linked below is its own dedicated product page with condition-matched pricing, inventory status, and supporting documentation. Review the specific model page for the bandwidth, channel count, sample rate, memory length, and interface set that matches the application requirement.

The AFG-4000 Series progression follows three primary axes documented in the datasheet's specification table. First, sine-wave bandwidth steps from 25 MHz (AFG-4125E, AFG-4125AE, AFG-4225E) through 35 MHz (AFG-4235), 60 MHz (AFG-4260), 80 MHz (AFG-4280), 100 MHz (AFG-4210H), and up to 250 MHz (AFG-4225H). Second, sample rate scales correspondingly: 125 MSa/s on the entry tier, 500 MSa/s on the 35–100 MHz mid-range, and 1.25 GSa/s on the AFG-4225H. Third, amplitude resolution improves from 14 bits on entry models to 16 bits on every model from AFG-4235 upward.

Additional differentiators captured in the comparison table that follows include channel count (AFG-4125E and AFG-4125AE are single-channel; all other models are dual-channel), arbitrary memory length (16 k points per channel on AFG-4125E/4125AE versus 10 M points per channel on AFG-4225E through AFG-4225H), touch screen support (available on AFG-4235 and above), LAN interface availability (AFG-4235 and above), and the built-in power amplifier function unique to the AFG-4125AE. Use the table below to align bandwidth, sample rate, memory, and interface requirements to the specific AFG-4000 Series model.

AFG-4210H 2 100 MHz 500 MSa/s
