UNI-T UTG9354T+ 350 MHz 4-Channel Elite-Series Arbitrary Waveform Generator: 16-Bit, 2.5 GSa/s, Touch Display

Overview

The UNI-T UTG9354T+ is a four-channel arbitrary waveform generator with a maximum sine output of 350 MHz, built around a 16-bit DAC and a 2.5 GSa/s sample rate (2× interpolation). All four channels deliver equal performance with full 20 Vpp output (high-Z), and an 8 pts to 128 Mpts per-channel arbitrary memory supports long-form custom stimulus. A 10.1-inch capacitive touch display replaces menu-driven navigation with direct parameter manipulation.

120 MHz square and 120 MHz pulse output, 1 µHz frequency resolution across the full 350 MHz range, harmonic distortion below 0.07% (DC to 20 kHz), and an 800 MHz hardware frequency counter. Fifteen analog and digital modulation types — including 3FSK, 4FSK, QAM, and the full BPSK / QPSK / OSK set. Linear, logarithmic, list, and step sweep. Three burst modes. Advanced Multi-Pulse, Multi-Tone, Sequence, Pattern, I/Q, and Expression functions. Over 200 built-in arbitrary waveforms with SPI / I²C / UART digital-protocol output.

UNI-T UTG9354T+ Details

Four Equal-Performance Channels, 20 Vpp

Four independent channels in the standard configuration, every one delivering identical performance — there is no derated second bank. Each channel produces the full output envelope to 20 Vpp (high-Z) and can run fully independently, so clock, data, trigger, and stimulus can all originate from one instrument at full specification on every channel.

UTG9354T+ channel coupling and merging
Frequency, amplitude, and phase coupling across channels; outputs merge into composite signals.

Channel Coupling and Merging

Channels can be freely coupled with configurable frequency, amplitude, and phase relationships (coupling ratio 0.0001 to 10,000), so a parameter change on one channel propagates to its coupled partners by a defined ratio and offset. Outputs can also be merged into arbitrary combinations — for example CH1 = CH1 + CH2 + CH3 + CH4 — producing summed and composite signals from a single instrument without external combiners.

Low-Distortion Output and High SNR

Digital sampling produces sine, square, ramp, pulse, arbitrary, harmonic, noise, DC, and PRBS waveforms with low distortion and low jitter. Total harmonic distortion stays below 0.07% from DC to 20 kHz, with a spurious-free dynamic range to −80 dBc. A small signal superimposed on a large DC offset retains a high signal-to-noise ratio — useful when the stimulus must be quieter than the device under test.

THD below 0.07% (DC to 20 kHz) with −80 dBc spurious-free dynamic range.
UTG9354T+ wide-dynamic pulse with fast, independently adjustable edges
Edge time adjustable in 100 ps steps; 3 ns minimum pulse width; per-pulse edge control.

Wide-Dynamic Pulse with Fast, Independently Adjustable Edges

The pulse generator offers high-precision adjustable edge times with increments as fine as 100 ps and a minimum pulse width of 3 ns (Typ.), generating high harmonic content comparable to a dedicated pulse generator. Edge time can be set independently for each pulse, down to a 2 ns minimum, and pulse jitter stays at 200 ps across the operating range.

15 Modulation Types in One Instrument

Fifteen analog and digital modulation schemes are built in: AM, FM, PM, DSB-AM, ASK, FSK, PSK, 3FSK, 4FSK, BPSK, QPSK, OSK, SUM, QAM, and PWM. Each channel supports independent or simultaneous internal/external modulation and internal/external/manual triggering, alongside Linear/Logarithmic/List/Step frequency sweep and N-cycle/gate/pulse-train burst.

UTG9354T+ multi-pulse and multi-tone generation
Multi-Pulse: 2–30 pulses with per-pulse edge control. Multi-Tone: 2–8 components.

Multi-Pulse and Multi-Tone Generation

Multi-Pulse produces pulse trains of 2 to 30 pulses with independently adjustable edge times and high/gap times for rapid, precise multi-pulse testing without custom code. Multi-Tone synthesizes 2 to 8 simultaneous frequency components, reproducing real-world multi-frequency signals for nonlinear-distortion analysis, wideband frequency-response work, and communication-system verification.

Sequence, Pattern, I/Q, and Expression Functions

Sequence chains up to 1,024 waveforms totalling 128 Mpts per channel with internal, external, manual, and timer start events for one-time loading of multiple test cases. Pattern outputs customizable code (NRZ/RZ/Manchester) at TTL, CMOS, ECL, and PECL logic standards. I/Q generation delivers baseband output at any symbol rate to 1.25 GSa/s. Expression builds complex waveforms directly from mathematical formulas.

Built-In Arbitrary Editor, Digital Bus, and 800 MHz Counter

The integrated arbitrary-waveform editor supports manual drawing, line drawing, and expression-based generation, and also runs on a PC over USB or LAN. Point-by-point output spans 8 pts to 128 Mpts with 16-bit vertical resolution. SPI, I²C, and UART digital-protocol output is built in, and a high-precision hardware frequency counter measures 100 mHz to 800 MHz with 8-digit resolution and selectable AC / DC / HF-reject coupling.

Applications

The UTG9354T+ envelope — four equal-performance channels, 2.5 GSa/s, 128 Mpts per channel, THD < 0.07%, 15-type modulation, the full advanced-function set, and a capacitive touch UI — targets benchtop work that needs genuine multi-channel stimulus, deep arbitrary support, or wide modulation coverage.

  • Multi-channel embedded development — four matched channels drive clock, data, trigger, and stimulus simultaneously from one instrument, conserving bench space while keeping every channel at full performance.
  • RF and communications stimulus — 3FSK, 4FSK, BPSK, QPSK, OSK, QAM digital modulation and SUM / DSB-AM analog modulation drive component characterization and protocol development across the full output range.
  • High-speed digital and serial-link test — fast adjustable edges with 100 ps steps, PRBS PN3 to PN33, and SPI / I²C / UART protocol output for interface and jitter-tolerance work.
  • Audio and instrumentation testing — THD below 0.07% from DC to 20 kHz when characterizing op-amp distortion, ADC noise floors, and audio-band response.
  • Long-form arbitrary playback — up to 128 Mpts per channel holds extended protocol streams, sensor-emulation traces, and complex composite waveforms.
  • I/Q and modulated-carrier work — baseband I/Q at any symbol rate to 1.25 GSa/s for communication-system verification.
  • Automated test (ATE) — LAN/USB remote control and instrument-manager software for synchronized multi-instrument benches.

Frequently Asked Questions

What does “2.5 GSa/s with 2× interpolation” mean in practice?

The DAC runs at a native rate, and a digital interpolation filter inserts estimated samples to produce a 2.5 GSa/s effective output stream. The reconstruction filter then sees a higher-rate stream and passes more high-frequency signal content with less alias distortion, giving finer detail in the upper portion of the output range.

Do all four channels run at full performance simultaneously?

Yes. The four channels are equal-performance — each delivers the full output envelope to 20 Vpp (high-Z) independently, with no derating when multiple channels are active. Channels can also be coupled by frequency / amplitude / phase ratio or merged into composite outputs.

What modulation, sweep, and burst envelope does the UTG9354T+ cover?

Modulation: 15 types — AM, FM, PM, DSB-AM, ASK, FSK, PSK, 3FSK, 4FSK, BPSK, QPSK, OSK, SUM, QAM, PWM. Sweep: Linear, Logarithmic, List, Step with internal / external / manual triggers. Burst: N-cycle (1 to 1,000,000 cycles), gate, and pulse-train.

What advanced waveform functions are included?

Multi-Pulse (2 to 30 pulses, per-pulse edge / high / gap times), Multi-Tone (2 to 8 components), Sequence (up to 1,024 waveforms, 128 Mpts per channel), Pattern (NRZ / RZ / Manchester at TTL, CMOS, ECL, PECL levels), I/Q (baseband to 1.25 GSa/s), and Expression (formula-defined waveforms) are all standard.

What digital-protocol outputs are supported?

SPI, I²C, and UART are built in. SPI and I²C run a 1 Hz to 50 MHz clock with up to 2,048-byte data depth; UART supports custom baud rates from 1 to 1,000,000 with configurable data, stop, and parity bits — useful for driving and emulating embedded serial buses directly from the generator.
