Overview

The UNI-T UTG2062B is a 60 MHz dual-channel arbitrary waveform generator built around a 16-bit DAC, 320 MSa/s sample rate, and a 16 Mpts arbitrary-waveform memory depth. The Advanced-Series chassis adds LAN connectivity, a 10 MHz external reference clock input and output, and a wider modulation envelope — 13 analog and digital modulation types including QAM and the full BPSK / QPSK / OSK / DSB-AM set — on top of the Classic-Series feature set.

25 MHz square / pulse output, 1 µHz frequency resolution across the full 60 MHz output range, harmonic distortion below 0.2%, a 6-bit hardware frequency counter (100 mHz to 200 MHz), and 160 built-in arbitrary waveforms. Sine, square, ramp, pulse, harmonic (up to 16th order), expression-defined, noise, DC, and arbitrary waveform shapes — with channel-coupling and channel-combination functions for dual-channel work that needs coordinated frequency, amplitude, or phase relationships.

Key Features

UNI-T UTG2062B Details

60 MHz Multi-Waveform Output

The UTG2062B produces nine waveform shapes at up to 60 MHz top-end on both channels: sine, square, ramp, pulse, harmonic, noise, DC, expression-defined, and arbitrary. Square and pulse output extend to 25 MHz with adjustable rise / fall time (typical 13 ns at 1 Vpp, 50 Ω) and pulse-wave jitter below 150 ps. Output amplitude is 1 mVpp to 10 Vpp into 50 Ω (2 mVpp to 20 Vpp into high-Z) across the full output range.

Expression Output

Eighteen function types — trigonometric, exponential, logarithmic, polynomial, absolute-value, and others — can be combined in column-method expressions to define the output waveform directly, without precomputing a sample buffer. The expression engine renders the result at the generator's full sample-rate / vertical-resolution capability. Useful for academic and research work where the waveform definition is the experimental variable.

13 Modulation Types

AM, FM, PM, ASK, FSK, PSK, BPSK, QPSK, OSK, SUM, DSB-AM, QAM, and PWM with internal or external source. The full PSK / BPSK / QPSK / OSK set supports communications-class digital-modulation stimulus; SUM and DSB-AM extend into analog double-sideband work; QAM adds quadrature amplitude modulation across configurable constellation depths. Modulating source is internal (sine, square, ramp, noise, arbitrary) or external via the analog modulation input.

160 Built-in Arbitrary Waveforms

The waveform library covers standard measurement shapes (Sinc, Gaussian, Lorentz, exponential rise / fall, etc.), communications stimulus (PRBS, multi-tone, ramp-modulated), automotive electrical waveforms (ignition, AC ripple, motor-back-EMF), and physiological signals (cardiac, respiratory). Up to 16 Mpts arbitrary-waveform memory per channel supports long-form custom stimulus uploaded via USB-Host or PC software.

Channel Combination & Coupling

The UTG2062B provides two channel-pairing modes. Channel combination sums the two-channel outputs into a single output port for dual-tone, multi-frequency, or noise-plus-signal stimulus. Channel coupling ties the channels parametrically — when frequency, amplitude, or phase is changed on one channel, the other auto-adjusts by the configured offset or ratio. Useful for differential signal generation and tracked sweep across a defined relationship.

Frequency Sweep & 16th-Order Harmonic Output

Linear and logarithmic frequency sweep modes cover the full 60 MHz output range with sweep time from 1 ms to 500 s. Internal, external, or manual trigger source. The built-in 16th-order harmonic generator synthesizes the fundamental plus harmonics 2 through 16 with adjustable amplitude and phase per order — useful for power-system harmonic stimulus, filter characterization, and academic harmonic-distortion teaching without an external mixer or summing amplifier.

Applications

The Advanced-Series envelope — 16 Mpts memory, LAN connectivity, 10 MHz reference In / Out, 13 modulation types, channel coupling — positions the UTG2000B family for benchtop work where the entry-tier doesn't reach but the elite-tier is over-specified.

• Communications-stimulus development — BPSK, QPSK, OSK, QAM digital modulation; SUM and DSB-AM analog modulation. ASK / FSK / PSK with configurable hop rate and depth.
• Long-form arbitrary playback — 16 Mpts memory holds extended protocol streams, sensor-emulation traces, and physiological waveforms that overflow a 4 kpts buffer.
• Power-system harmonic testing — 16th-order harmonic generator drives filter, transformer, and meter harmonic-distortion characterization without external mixing.
• Differential signal generation — channel coupling produces phase-tracked, amplitude-tracked, or frequency-tracked output pairs for differential-circuit stimulus.
• Automated test (ATE) — LAN-based SCPI control with 10 MHz reference clock In and Out for synchronized multi-instrument benches.
• Academic and research — expression-defined waveform output supports experimental designs where the waveform mathematics is the experimental variable.
