The AFG – 4000 Series Arbitrary Function Generator from GWINSTEK is a versatile and high – performance signal generation solution. It is the first series from the brand to feature an 8 – inch large touch screen (for models above 35MHz), providing users with an intuitive and convenient operation experience. With a wide range of frequency bandwidths from 25MHz to 250MHz, it can meet diverse signal generation needs in various fields such as electronics research, education, and industrial testing.
Key Features
- Multi – channel Options:
- Single – channel models: AFG – 4125E/4125AE (25MHz), suitable for applications that require a single signal source.
- Dual – channel models: AFG – 4225E/4235/4260/4280/4210H/4225H, offering frequency bandwidths of 25MHz/35MHz/60MHz/80MHz/100MHz/250MHz. The dual – channel models support related settings like frequency coupling, amplitude coupling, and tracking, enabling quick configuration of two – channel output.
- Abundant Built – in Waveforms: Includes sine, square, triangle, ramp, pulse, noise, harmonic wave, and arbitrary wave. There are 146 arbitrary waveforms available for editing and output, providing great flexibility in signal generation.
- High Resolution: Features a minimum frequency resolution of 1μHz, ensuring precise control over the generated signals’ frequency.
- Variable Sampling Rates:
- AFG – 4225H: 1.25GSa/s
