The UNI-T UTG2122B is a dual-channel arbitrary waveform / function generator with 120 MHz sine output, 14-bit vertical resolution and a sample rate of 500 MSa/s. It supports sine, square, ramp, pulse, noise and arbitrary waveforms, plus AM/FM/PM/ASK/FSK/PSK modulation.
Typical use: stimulate circuits under test on the bench, generate test waveforms for filter and amplifier characterisation.
