GW Instek AFG-4125AE function generator
Details
The GW Instek AFG-4125AE is a single-channel function generator with a maximum bandwidth of 25MHz and a sample rate of 125MSa/s. As part of the entry-level budget models of the GW Instek AFG-4000 series, it features a high resolution of 14 bits and a small memory depth of 16kpts per channel. The AFG-4125AE also has multiple waveform outputs such as sine, triangle, square, ramp, pulse, noise, arb, and harmonic. The AFG-4125AE is the only one in the AFG-4000 series which features a built-in power amplifier, with a power output of 10W and an amplification factor of 10x to reach a maximum output of 22V. The generator is multifunctional and includes many features such as a sweep, burst, counter function, and multiple analog and digital modulation modes. The AFG-4125AE also has a waveform editing function with 146 arbitrary built-in waveforms for editing and output. The device features a 8" LCD, making waveforms easily readable. Furthermore, the device features USB host/device interfaces for communication.
