UTG2122B Function/Arbitrary Waveform Generator

Precision Dual-Channel Direct Digital Synthesis Architecture

The UNI-T UTG2000B Series Function/Arbitrary Waveform Generators are high-performance benchtop instruments engineered to deliver exceptionally stable, pure, and low-distortion signals across demanding electronics engineering applications. Operating on advanced Direct Digital Synthesis (DDS) technology, the series includes models with maximum sine wave frequency outputs of 60MHz (UTG2062B), 80MHz (UTG2082B), and 120MHz (UTG2122B). Featuring a high sampling rate of 320 MSa/s and an ultra-fine full-band frequency resolution of 1 μHz, the UTG2000B ensures precise signal fidelity across the entire spectrum. Built with two independent, fully feature-equivalent channels, the unit supports both standalone signal generation and channel-coupling modes to synchronize phase, frequency, and amplitude across multi-device test topologies.

Deep Arbitrary Memory and 16-Bit Vertical Resolution

Equipped with an advanced 16-bit vertical Digital-to-Analog Converter (DAC) and an expansive arbitrary waveform memory depth ranging from 8 pts up to 16 Mpts per channel, the UTG2000B series reproduces intricate signals with exceptional dynamic range and low phase noise. Engineers can generate custom mathematical functions using the built-in mathematical expression output function or construct highly complex real-world waveforms to simulate sensor glitches, power supply transients, and noisy communication signals without signal clipping or interpolation artifacts. The high vertical resolution ensures accurate step transitions even at microvolt amplitude scales.

Comprehensive Modulation, Harmonic, and Sweep Capabilities

The UTG2000B series offers an exhaustive library of digital and analog modulation schemes, including AM, FM, PM, PWM, ASK, FSK, PSK, BPSK, QPSK, OSK, DSB-AM, SUM, and QAM. For specialized RF, power electronics, and audio testing, the instrument features dedicated harmonic generation modes capable of outputting odd and even harmonics up to the 16th order, making it an essential tool for evaluating non-linear distortion in power amplifiers, active filters, and receiver architectures. Advanced linear and logarithmic sweep modes alongside N-cycle and gated burst operation modes provide total flexibility over stimulus-response characterization.

Humanized Graphical Interface and SCPI System Connectivity

Featuring a vibrant 4.3-inch WVGA TFT LCD display (800x480 resolution), the UTG2000B provides clear, intuitive visual confirmation of dual-channel waveform parameters simultaneously. Front-panel USB Host ports enable rapid saving and loading of custom waveform data files, while rear-panel USB Device and LAN (LXI compliant) ports support seamless computer remote control via standard SCPI commands. A dedicated 10MHz external clock input/output port enables synchronization with high-precision master atomic clocks or central system-level test racks.

Versatile Technical Application Use-Cases

The UTG2000B series is ideal for a broad range of professional engineering workflows, including embedded microcontroller clocking, automotive sensor emulation (CAN/LIN bus noise injection and ABS sensor signals), medical electronic prototyping (ECG and EEG simulation), wireless R&D, university laboratory education, and automated production testing. Its rapid square wave rise and fall times (under 9ns) make it equally adept at driving high-speed digital logic circuits and evaluating semiconductor switching dynamics.
