Four Equal-Performance Channels for Complex Test Setups
One of the most important advantages of the UTG9000T+ series is its four-channel architecture. Every channel provides the same core performance, allowing engineers to generate multiple independent signals without sacrificing bandwidth or output capability on the secondary channels. Each channel can deliver up to 20 Vpp into a high-impedance load, and channels can be operated independently, coupled, or merged to create composite signals.
This makes the UTG9000T+ particularly useful for applications where clock, data, trigger, reference, and stimulus signals need to be generated simultaneously. Instead of relying on multiple generators with different channel capabilities, engineers can use one synchronized four-channel platform.
Two Models for Different Frequency Requirements
The UTG9000T+ family consists of two models:
- UTG9354T+ — 350 MHz maximum sine frequency, 120 MHz square/pulse frequency, 4 channels
- UTG9504T+ — 500 MHz maximum sine frequency, 170 MHz square frequency and 120 MHz pulse frequency, 4 channels
Both models provide 16-bit vertical resolution, 2.5 GSa/s sampling with 2× interpolation, four equal-performance channels, 8-point to 128 Mpoint arbitrary waveform memory per channel, and an extensive library of modulation and waveform-generation functions.

16-Bit Resolution for High-Fidelity Signal Generation
The UTG9000T+ is built around a 16-bit DAC architecture, providing 65,536 amplitude levels for precise waveform generation. This higher vertical resolution is especially useful when a test requires accurate reproduction of small amplitude variations or low-level signals superimposed on larger offsets.
For communications, instrumentation, and precision analog testing, improved amplitude resolution can help reduce quantization effects and provide more accurate stimulus signals. The UTG9504T+, for example, provides a spurious-free dynamic range of up to −80 dBc and total harmonic distortion below 0.07% from DC to 20 kHz.
This combination of resolution and low distortion makes the series suitable for applications ranging from audio and analog characterization to advanced RF and digital-system testing.
2.5 GSa/s Sampling with 2× Interpolation
Both UTG9000T+ models provide a 2.5 GSa/s sample rate with 2× interpolation. The interpolation architecture inserts calculated samples into the digital waveform stream before reconstruction, helping maintain signal quality as output frequency increases.
The result is a signal-generation platform capable of producing detailed high-speed waveforms while maintaining precise control over waveform shape and timing.
This capability is particularly useful for high-speed digital testing, RF stimulus generation, and applications where the generated signal must accurately reproduce a complex waveform.
Deep Arbitrary Waveform Memory
The UTG9000T+ provides 8-point to 128 Mpoint arbitrary waveform memory per channel. This allows engineers to generate long-form custom signals, complex test patterns, protocol sequences, sensor-emulation waveforms, and other non-standard stimuli.
The built-in arbitrary waveform editor supports manual drawing, line-based waveform creation, and mathematical expression-based generation. PC-based waveform editing is also supported through USB or LAN connectivity.
More than 200 built-in arbitrary waveforms are included, giving users a substantial library of ready-to-use signals while still providing the flexibility to create completely customized waveforms.
Flexible Multi-Channel Coupling and Signal Merging
The four channels can operate independently or be coupled through configurable frequency, amplitude, and phase relationships. This allows a change on one channel to propagate to another according to a defined ratio or offset.
The outputs can also be merged to create composite signals. For example, multiple channels can be mathematically combined into a single output, allowing engineers to build more complex stimulus conditions without requiring external signal combiners.
This flexibility is valuable for communications testing, multi-tone experiments, system simulation, and applications requiring controlled relationships between multiple signals.
Advanced Modulation Capabilities
The UTG9000T+ includes an extensive selection of analog and digital modulation functions. Supported modulation types include AM, FM, PM, DSB-AM, ASK, FSK, 3FSK, 4FSK, PSK, BPSK, QPSK, OSK, QAM, PWM, and SUM.
These capabilities allow engineers to generate realistic communication signals without requiring separate modulation equipment.
Digital modulation support is particularly useful for RF component evaluation, receiver testing, communication-system development, and educational applications where different modulation formats need to be generated and compared.
I/Q Generation for Communications Testing
The UTG9000T+ also includes I/Q waveform generation, supporting baseband signal generation at symbol rates up to 1.25 GSa/s.
I/Q generation provides a practical way to create complex baseband signals for communications-system development and verification. Engineers can use the generator to create controlled I/Q stimuli for testing RF front ends, modulation chains, receivers, and other communication-system components.
The combination of I/Q generation and digital modulation capabilities makes the UTG9000T+ a versatile stimulus source for RF and wireless development.
Multi-Pulse and Multi-Tone Generation
For more complex test scenarios, the UTG9000T+ provides dedicated Multi-Pulse and Multi-Tone functions.
Multi-Pulse generation supports pulse trains containing multiple individually controlled pulses, while Multi-Tone generation can combine multiple frequency components into a single stimulus. The UTG9504T+ supports two to eight simultaneous tones and up to 30 pulses within the Multi-Pulse function.
These functions are useful for nonlinear-distortion testing, frequency-response characterization, communication-system verification, and applications where real-world multi-component signals need to be reproduced.
Fast Pulse Generation and Adjustable Edges
The UTG9000T+ is also capable of generating high-speed pulse signals with adjustable edge times. On the UTG9504T+, edge time can be adjusted in increments as fine as 100 ps, while the minimum pulse width is approximately 3 ns.
This provides engineers with greater control over the characteristics of digital stimulus signals. Edge-time adjustment can be particularly useful for evaluating receiver sensitivity, timing margins, signal integrity, and jitter tolerance.
PRBS generation from PN3 through PN33 is also supported, with data rates ranging from 1 µbps to 300 Mbps on the UTG9504T+.
Digital Protocol Signal Generation
A major advantage of the UTG9000T+ is its integrated digital-bus output capability. The generator can directly produce SPI, I²C, and UART protocol signals, allowing engineers to create repeatable digital stimuli without requiring a separate protocol generator.
This capability is particularly useful in embedded-system development and interface testing. Engineers can combine protocol signals with analog waveforms or clock signals on the other channels to reproduce realistic system conditions.
Sequence, Pattern, and Expression Functions
The UTG9000T+ provides several advanced waveform-generation modes for building sophisticated test scenarios.
The Sequence function allows multiple waveforms to be linked together into a programmable test sequence. Pattern generation supports configurable digital-code outputs, while the Expression function allows mathematical formulas to be used to create complex waveforms.
These capabilities are useful when standard sine, square, pulse, or arbitrary waveforms are not sufficient to reproduce the behavior of a real-world system.
800 MHz Hardware Frequency Counter
Both models include an integrated hardware frequency counter capable of measuring frequencies up to 800 MHz. The counter provides eight-digit resolution and supports selectable coupling modes for different measurement conditions.
Having a frequency counter integrated into the waveform generator provides an additional measurement function without requiring a separate counter for many bench applications.
Large Touchscreen Interface
The UTG9000T+ features a 10.1-inch capacitive touchscreen with a 1280 × 800 resolution. The interface provides direct access to waveform parameters and makes it easier to configure multi-channel signals and advanced generation functions.
For complex multi-channel testing, the touchscreen provides a convenient way to monitor channel settings, modulation parameters, coupling relationships, and waveform-generation modes from a single interface.
Remote Control and Automated Test Integration
The UTG9000T+ supports USB and LAN connectivity, making it suitable for automated test environments and remotely controlled laboratory setups. The instrument can be integrated into PC-based workflows and automated measurement systems where repeatable signal generation is required. (uni-trendus.com
This is particularly valuable in production and compliance testing, where the same stimulus conditions may need to be reproduced across a large number of devices under test.
For multi-instrument environments, remote control also simplifies the coordination of signal generators with oscilloscopes, spectrum analyzers, power supplies, and other test equipment.
Built for RF, Embedded, and High-Speed Digital Development
The UTG9000T+ is designed to cover a wide range of advanced signal-generation requirements.
For RF and communications development, the combination of high-frequency sine generation, digital modulation, I/Q capabilities, multi-tone generation, and low-distortion output provides a flexible source for component and system testing.
For embedded-system development, four equal-performance channels allow engineers to generate clocks, data, triggers, analog stimuli, and other signals simultaneously. Built-in SPI, I²C, and UART output further simplifies interface testing.
For high-speed digital testing, adjustable pulse edges, PRBS generation, sequence functions, and deep arbitrary memory enable engineers to reproduce controlled and repeatable digital stress conditions.
Choosing the Right UTG9000T+ Model
The choice between the two UTG9000T+ models is primarily based on the required maximum frequency.
The UTG9354T+ provides 350 MHz maximum sine output and 120 MHz square/pulse output, making it a strong choice for VHF/UHF signal generation, embedded-system development, digital stimulus, and general-purpose advanced waveform testing.
The UTG9504T+ increases maximum sine output to 500 MHz and square-wave output to 170 MHz, providing additional frequency headroom for higher-frequency RF applications, 433 MHz ISM signal generation, and more demanding high-speed digital stimulus.
Both models share the same four-channel, 16-bit architecture and broad advanced-function set, so the decision can be made primarily according to bandwidth requirements.
Ideal Applications
The UTG9000T+ series is well suited to a variety of professional engineering environments. In RF and wireless development, its modulation, I/Q, multi-tone, and high-frequency output capabilities provide flexible stimulus for communications-system testing.
For embedded and automotive electronics, four equal-performance channels can generate multiple clocks, control signals, data streams, and analog stimuli simultaneously. The integrated SPI, I²C, and UART output further simplifies digital-interface testing.
In high-speed digital and serial-link validation, PRBS patterns, adjustable pulse edges, deep arbitrary memory, and sequence functions allow engineers to create repeatable stress and timing conditions.
The series is also valuable for audio and analog testing, where low harmonic distortion and high vertical resolution provide clean stimulus for amplifiers, ADCs, DACs, filters, and other analog circuits. For automated test equipment, LAN/USB control and four fully capable channels make the UTG9000T+ a flexible source for programmable production and laboratory test systems.
