UNI-T UTG2062B Advanced-Series Arbitrary Waveform Generator
Overview
The UNI-T UTG2062B is a two-channel arbitrary waveform generator delivering 60 MHz sine wave output with 320 MSa/s sampling, 16-bit vertical resolution, and 16 Mpts waveform memory. The 16-bit DAC produces 65,536 amplitude levels—significantly better than 14-bit generators—delivering cleaner signals with lower quantization noise for applications that demand accurate waveform reproduction.
The UTG2000B platform includes 13 modulation types (AM, FM, PM, PWM, ASK, FSK, PSK, BPSK, QPSK, OSK, DSB-AM, SUM, QAM), expression-based waveform synthesis, 16th-order harmonic generation, channel coupling, sweep functions (linear and logarithmic), and burst output. The 4.3-inch TFT display and straightforward menu system provide quick access to all functions. USB and LAN connectivity with SCPI support enables automated test integration.

Key Features
- 60 MHz Sine / 25 MHz Square & Pulse — Dual-channel output covers standard analog and digital signal generation needs. 1 μHz frequency resolution enables precise frequency placement for filter characterization and frequency response measurements.
- 320 MSa/s Sampling with 16-Bit Resolution — The 16-bit DAC provides 4× the amplitude resolution of 14-bit generators, producing cleaner output with lower quantization noise. Critical for applications requiring accurate low-level signal reproduction.
- 16 Mpts Arbitrary Waveform Memory — Store and replay complex waveforms at full fidelity. 160+ built-in waveforms cover common signal shapes. Free PC software for custom waveform creation and USB upload.
- 13 Modulation Types Including QAM — AM, FM, PM, PWM, ASK, FSK, PSK, BPSK, QPSK, OSK, DSB-AM, SUM, and QAM modulation with internal and external source options.
- Expression Output — Define waveforms as mathematical expressions using Vout = f(x) notation. Create complex signals from equations without building arbitrary waveform files—useful for generating signals that follow known transfer functions.
- 16th-Order Harmonic Generation — Create harmonically rich waveforms with individual control over each harmonic's amplitude and phase. Test harmonic distortion performance of amplifiers, evaluate filter rejection, or generate waveforms matching specific spectral profiles.
- Channel Coupling — Synchronize frequency, amplitude, or phase changes across both channels automatically. Simplifies differential signal generation and matched-channel testing.
- Sweep & Burst Modes — Linear and logarithmic sweep for frequency characterization. N-cycle, gated, and infinite burst types for pulse testing and event simulation.
Expression Output and Harmonic Synthesis
The expression output function lets you define waveforms mathematically—enter an equation like f(x) = sin(x) + 0.5*sin(3x) and the UTG2062B generates the corresponding output directly. This is faster than creating an arbitrary waveform file for signals that can be described analytically, and it's particularly useful for generating test signals that match known transfer functions, combining multiple signal components, or exploring waveform shapes during development.
The 16th-order harmonic generation complements expression output by providing structured control over harmonic content. Select even harmonics, odd harmonics, all harmonics, or define custom sets. Adjust each harmonic's amplitude (as a percentage of fundamental) and phase independently. This creates waveforms with precisely controlled spectral content—essential for testing THD measurement systems, evaluating filter performance across harmonics, and generating realistic distorted signals.

Frequently Asked Questions
What's the difference between the UTG2000B and UTG2000X?
The UTG2000X series offers higher sample rate (1.25 GSa/s vs 320 MSa/s), deeper waveform memory (64 Mpts vs 16 Mpts), additional modulation types (15 vs 13), a touchscreen interface, PRBS generation, and a hardware frequency counter. The UTG2000B provides the same 16-bit resolution at a lower price point—ideal when sample rate headroom and deep memory aren't critical requirements.
What's included with the UTG2062B?
The UTG2062B ships with the instrument, power cable, BNC cables, USB cable, and UNI-T's 3+2 warranty (3 years standard plus 2 additional years with free registration—5 years total). Both channels are fully active. PC waveform editing software, user manual, and programming guide are available from the UNI-T website.
