On July 8, 2025, RIGOL released the DG5000 Pro multi-channel waveform generation solution and the SPQ digital array measurement and control system to help customers tackle more complex test scenarios.

More Possibilities: New Additions to the DG5000 Pro Series Function/Arbitrary Waveform Generators

In 2024, RIGOL launched the newly upgraded DG5000 Pro Series dual-channel isolated function/arbitrary waveform generators, featuring up to 500 MHz bandwidth, 2.5 GSa/s sample rate, and 16-bit resolution. Following its launch, the series quickly earned engineers’ trust and praise for its outstanding performance.

Today, RIGOL has added six new models—four-channel and eight-channel variants—upgrading DG5000 Pro into a next-generation multi-channel waveform generation platform. The upgraded DG5000 Pro Series delivers picosecond-level precise synchronization and clean, galvanically isolated outputs to address complex, high-precision multi-channel test challenges.

1. High Sampling Rate, High Fidelity

Embodying a “high-end from the start” design philosophy, the DG5000 Pro ensures uncompromising performance in any configuration. With up to 2.5 GSa/s sample rate and 16-bit vertical resolution, it captures and reproduces every fine detail of your signals. Whether standard functions or complex arbitrary waveforms, signals are rendered with exceptional fidelity, giving you a stable, trustworthy “gold-standard” source. Meanwhile, all DG5000 Pro models can output square waves up to 170 MHz with rise times as fast as 0.8 ns—making even the standard configuration well-suited for high-speed digital signal emulation and test.

2. High Signal Fidelity, Ultra-low Jitter

Powered by RIGOL’s SiFi II high-fidelity signal technology, DG5000 Pro limits jitter to an impressive 200 ps. Every waveform edge is exceptionally stable and clean. Whether used as a clock source for high-speed systems or for timing-critical tests, ultra-low jitter ensures timing accuracy in the time domain.

3. High-density Multi-channel Design, Extreme Compact Space Efficiency

DG5000 Pro innovatively integrates up to eight high-performance output channels in a standard chassis. Compared with traditional multi-instrument setups, it can save up to two-thirds of bench and rack space. This high-density approach replaces bulky instrument stacks with a single device—greatly simplifying the build and management of complex test systems.

4. Picosecond-level Synchronization and Nanosecond-level Flexible Delay Adjustment

The true value of multi-channel lies in precise timing control. DG5000 Pro achieves inter-channel skew better than 500 ps for inherently consistent multi-channel signals; on top of this, it provides adjustable output delay of ±200 ns. This powerful combination of “precise synchronization” and “flexible adjustment” enables both perfectly coherent signal groups and realistic propagation-delay emulation to build complex timing relationships—ideal for phased-array research, multi-channel system simulation, and other advanced applications.

5. Isolated Channel Group Design, Both Pure and Flexible

Signal integrity is critical in complex systems. DG5000 Pro employs an advanced grouped isolation architecture, organizing channels into four fully independent isolation pairs (CH1/2, CH3/4, …). Each group is completely isolated from the others and from chassis ground, effectively eliminating ground-loop interference when testing multiple independent circuits. Beyond purity and safety, the shared reference within each group naturally suits differential signal generation—delivering unmatched flexibility for mixed-signal testing.

The DG5000 Pro Series also supports advanced features including flexible multi-pulse, advanced waveform sequencing, multi-tone modulation, PRBS, and user-defined pattern outputs—empowering power semiconductor test, complex automated test, device characterization, and high-speed system test to boost engineering productivity.

The SPQ Digital Array Measurement and Control System, Designed for Advanced Computing

RIGOL’s solutions portfolio now includes the SPQ digital array measurement and control system. Built on a modular design, SPQ is partitioned into multiple functional modules, each deeply optimized for specific application scenarios:

Microwave Control Module: It realizes high-precision and diversified XY microwave signal control to meet the complex RF control signal requirements in advanced computing measurement and control;

Microwave Reading and Analysis Module: It supports real-time data acquisition, processing, and feedback to improve testing efficiency;

Bias Voltage Module: It can provide a stable high-bandwidth Z bias voltage;

High-precision Synchronous Clock and Trigger Distribution Module: It ensures the synchronous operation of multiple modules and enhances the system-level measurement and control ability.

Evolving through multiple phases, SPQ has matured into an advanced-computing-focused measurement and control platform centered on instruction-set compilation. This breakthrough overcomes inherent limitations of traditional M&C equipment in real-time performance, scalability, and noise suppression—delivering an efficient, cost-effective solution for high-density, low-noise advanced computing scenarios.

1. Higher Microwave Signal Quality

SPQ adopts high-sample-rate direct digital output, replacing traditional baseband mixing and fundamentally eliminating LO leakage and IQ imbalance. Direct digital output ensures consistent amplitude/phase and accurate phase alignment for each microwave pulse; waveforms remain uncorrupted. Overall signal purity and long-term stability are significantly improved, providing a precise and reliable drive foundation for noise-sensitive compute units.

2. Simple and Clear Architecture, Rapid Construction of Measurement and Control System

With direct digital output, each compute unit needs only a single signal port—no mixers or multi-channel synthesis. Wiring is drastically reduced and bring-up simplified, allowing system build-out in very short time. The architecture is easy to understand and maintain, providing efficient, reliable hardware support for experiments involving hundreds of compute units.

3. High Integration, Full Coverage of Small to Large Requirements

Within a 19-inch 16U chassis, SPQ integrates 500+ microwave control channels with inter-channel isolation ≥ 65 dBc to effectively suppress crosstalk. Overall integration is increased by 10× versus traditional solutions. Full-stack M&C capability and simplified wiring balance scale and stability, enabling expansion from a few bits to massive-bit systems with ease.

4. Extremely Low System Noise, Optimized Bit Performance

SPQ achieves −142 dBc/Hz phase noise at 100 MHz output with 1 kHz offset, and noise power spectral density below −160 dBm/Hz—creating a clean environment for highly noise-sensitive compute units. Decoherence time is significantly extended, and the operational window is more than doubled versus traditional approaches, ensuring long-term stability for deep experiments.

5. Integration of Supercomputing and Advanced Computing

Through PXIe‑PCIe bridging, SPQ can connect directly to supercomputing servers over multiple optical fibers using the PCIe protocol, supporting Peer‑to‑Peer data exchange. End-to-end latency is reduced to the microsecond level, and bandwidth exceeds 6 GB/s. Real-time synergy between the exponential state-space of advanced computing and the large-scale numerical capability of supercomputing can compress cycles—for example, materials R&D—from years to months.

6. Dedicated Instruction Set and Active Reset, Realizing Efficient Measurement and Control

SPQ incorporates a dedicated M&C instruction set with a feedback path of < 300 ns. It can issue an active reset waveform immediately after each gate operation; multiple resets increase ground-state probability. Compared with passively waiting for decoherence, overall experiment efficiency improves by more than 10×, establishing a real-time control foundation for logic compute units and diverse encoding/decoding research.

As RIGOL’s latest achievement in measurement and control technology, the SPQ system—combining modular architecture, digital processing, high-density integration, and ultra-low noise—addresses the challenges of advanced-computing M&C and accelerates research. The SPQ digital array M&C system has been deployed at dozens of customers domestically with long-term stable operation, and continues to evolve in step with the latest functional and performance demands—becoming a benchmark solution in the field of advanced-computing measurement and control.
