About this item
The UNI-T UTG4122A is a dual-channel function/arbitrary waveform generator offering up to 120 MHz sine output and 500 MSa/s sampling for high-fidelity signal generation. Based on Direct Digital Synthesis (DDS), it provides stable, low-distortion waveforms with 1 µHz resolution, making it suitable for both laboratory and field environments. The upright design includes an 8″ TFT LCD with intuitive front-panel controls multifunction knob, soft keys, numeric keypad, and directional keys streamlining waveform configuration and parameter adjustment. Each channel supports continuous, modulation, sweep (linear/log), and burst modes, with 32 Mpts memory depth and 16-bit vertical resolution enabling precise arbitrary waveform playback. Standard waveforms include sine, square/pulse, ramp, harmonic, noise, DC, and arbitrary, covering frequency ranges from 1 µHz to 120 MHz for sine and up to 40 MHz for square/pulse on this model. Rich modulation options (AM, FM, PM, ASK, FSK, PSK/BPSK/QPSK, OSK, PWM, SUM, QAM) facilitate communications testing. Additional functions such as TTL-level digital protocol outputs (I2C, SPI, UART), frequency counter, external/internal 10 MHz reference I/O, and LAN/USB interfaces for remote control and waveform upload enhance versatility. Ergonomic layout and context-sensitive help aid usability. The UTG4122A’s design targets R&D, education, maintenance, and automated test systems requiring reliable, flexible signal emulation.
