UNI-T UTG2122B Waveform Generator
The UNI‑T UTG2122B Waveform Generator is a precision bench instrument that employs direct digital synthesis (DDS) to deliver stable, low‑distortion signals across a wide frequency range. Offering dual independent channels, it supports sine, square, ramp, pulse, noise, arbitrary, harmonic, and expression‑defined waveforms with full‑band resolution down to 1 μHz. With a sampling rate of 1.28 GSa/s and 16‑bit vertical resolution, it achieves sine‑wave outputs up to 120 MHz, square and pulse outputs up to 30 MHz, and ramp outputs to 5 MHz.
The front panel’s 4.3″ TFT color display and intuitive knob‑and‑key interface streamline setup, while USB Host/Device, LAN, and 10 MHz I/O facilitate integration into automated test systems. Advanced features include built‑in burst, sweep, and 18‑function expression modes, plus rich modulation capabilities (AM, FM, PM, ASK, FSK, PSK, BPSK, QPSK, OSK, SUM, DSBAM, QAM, PWM). Nonvolatile memory stores up to 200 waveforms (8–16 M points), and a USB flash drive slot supports up to 32 GB external storage.
Housed in a compact 305 × 230 × 93 mm chassis with forced‑air cooling, it meets CAT II safety standards and operates from 100–240 VAC. Ideal for R&D, education, and production, the UTG2122B balances high performance with user‑friendly design.
