The AFG-4000 series is GWInstek's first arbitrary waveform signal generator equipped with an 8 'large touch screen. The frequency of the single channel model is 25MHz, while the dual channel model has frequency options of 250MHz/100MHz/80MHz/60MHz/35MHz/25MHz. The entire series offers a high resolution of 1 μ Hz and is equipped with standard waveforms such as sine waves, square waves, triangular waves, pulse waves, noise waves, harmonics, etc. The sampling rate of the highest frequency 250MHz model is 1.25GSa/s; The sampling rate for models ranging from 35MHz to 100MHz is 500MSa/s; The sampling rate of the entry-level model at 25MHz is 125MSa/s. For vertical resolution, models ranging from 35MHz to 250MHz have a 16 bit resolution, while entry-level models at 25MHz have a 14 bit resolution. In addition, in terms of storage depth, the 35MHz-250MHz model is 10M, and the entry-level 25MHz model is 16k. The entire series is equipped with 146 arbitrary waveforms for editing and output.

The dual channel model provides dual channel related settings, such as frequency coupling, amplitude coupling, and tracking, allowing users to quickly set outputs related to both channels. In terms of modulation function, the AFG-4000 series provides AM、DSB-AM、FM、PM、PWM、ASK、PSK、BPSK、OPSK、FSK3FSK、4FSK、OSK、SUM Waiting for modulation signal output. The standard features include Sweep and Burst outputs, as well as counter functionality. AFG4125AE has a built-in power amplifier. The power output of the amplifier reaches 10W, the amplification factor reaches 10 times, and it produces a maximum output of 22V. The independent input/output power amplifier provides a bandwidth range of 5Hz to 100kHz, which can be used for audio signals and other application requirements.

The AFG-4000 series is equipped with an 8 "high-resolution TFTLCD, and models above 35MHz are equipped with touch screen functionality. Touchscreens can make inputting parameters more convenient. Users only need to touch parameters such as frequency, amplitude, or DC offset, and a digital input window will appear on the screen. Users can intuitively input parameters through this window or the numeric keys on the AFG-4000 panel. Through the 8 "large screen, touch screen, and various built-in waveforms, users can freely control it to meet their signal generation needs.

Frequency 25MHz models: AFG-4125E/4125AE/4225E have built-in USB Host/Device interfaces, and models with frequency ranges from 35MHz to 250MHz come standard with USB Host/Device and LAN interfaces.
