June 25, 2026 – In an era where the boundaries of digital communication, radar technology, and quantum research are expanding at an exponential rate, the demand for test and measurement equipment capable of keeping pace has never been higher. Today, Saelig Company, Inc., a prominent North American distributor of advanced electronic components, announced the immediate availability of the Rigol Technologies DG70000 Series Arbitrary Waveform Generators (AWGs). This launch marks a significant milestone for Rigol, signaling the company’s decisive entry into the top-tier of high-performance instrumentation.
Main Facts: A Paradigm Shift in Signal Fidelity
The DG70000 Series is not merely an iterative update; it is a fundamental architectural leap. Powered by Rigol’s proprietary SiFi III technical platform, the series is engineered to provide unprecedented control over waveform synthesis. Available in both 2-channel and 4-channel configurations, the DG70000 is designed to bridge the gap between laboratory research requirements and the rigorous demands of high-speed industrial design.
At the core of the DG70000’s capability is its ability to deliver a 5GHz analog bandwidth coupled with a maximum interpolated sampling rate of 12GSa/s. In the competitive landscape of AWGs, this level of raw performance allows engineers to tackle signal generation tasks that were previously reserved for multi-instrument setups or highly specialized, cost-prohibitive systems. By maintaining high-fidelity output even at the upper limits of its frequency range, the DG70000 ensures that complex signals—essential for verifying modern silicon and communication protocols—remain distortion-free and highly repeatable.
Chronology: The Evolution of Rigol’s SiFi Platform
The path to the DG70000 began with Rigol’s foundational work on the SiFi (Signal Fidelity) architecture.
- Early Development: Rigol initially disrupted the mid-range market with the first iteration of the SiFi platform, which focused on minimizing aliasing and jitter in standard waveform generation.
- The Scaling Phase: Over the last decade, Rigol expanded its portfolio to address higher frequency domains, gradually increasing vertical resolution and sampling rates across their standard AWG lines.
- The Technical Breakthrough (2024-2025): The internal development of the SiFi III platform marked a transition toward high-speed DAC (Digital-to-Analog Converter) optimization. By focusing on the integration of native IQ modulation and ultra-low noise floors, Rigol successfully moved from general-purpose instrumentation into the high-end RF domain.
- Market Launch (June 2026): The culmination of these efforts is the DG70000, unveiled today by Saelig, representing the company’s most sophisticated test tool to date.
Supporting Data: Technical Specifications and Performance Metrics
The DG70000 Series distinguishes itself through a meticulous balance of speed, resolution, and noise control. While many generators sacrifice signal integrity to reach high sampling rates, Rigol has maintained a 16-bit vertical resolution, a critical feature for engineers performing sensitive device characterization.
Precision Engineering Metrics
- Sampling Rate: 12GSa/s (interpolated), providing the temporal resolution required for high-speed digital logic testing.
- Analog Bandwidth: 5GHz, enabling the generation of high-frequency carriers and wide-band signals.
- Vertical Resolution: 16-bit, which translates to a vastly improved dynamic range compared to standard 12-bit or 14-bit generators.
- Spurious-Free Dynamic Range (SFDR): -70dBc, ensuring that the spectral output remains clean of harmonic interference.
- Jitter Performance: Total jitter is kept to a remarkable 10ps, with random jitter measuring a mere 350fs. This makes the DG70000 an ideal candidate for testing clock recovery circuits and jitter-sensitive high-speed interfaces.
Advanced Modulation Capabilities
The series supports complex vector modulation, accommodating modern wireless standards that utilize 1024QAM. The inclusion of a 1.5GHz modulation bandwidth and an integrated Digital Up Converter (DUC) allows for the direct output of RF modulated signals. Furthermore, the system’s agile frequency-hopping mode—capable of hop intervals as low as 128ns—is specifically designed to simulate the unpredictable frequency patterns found in modern radar systems and electronic warfare countermeasures.
Official Perspectives: Industry Implications
The introduction of the DG70000 series is being viewed by industry analysts as a strategic move to democratize high-performance testing. Historically, instruments with 5GHz bandwidths were largely locked behind massive capital expenditure hurdles.
"The release of the DG70000 series by Rigol, through our partnership, is a testament to the maturation of Chinese test and measurement engineering," noted a spokesperson from Saelig Company, Inc. "We have spent decades vetting instrumentation, and the leap in fidelity provided by the SiFi III platform addresses a specific void in the market. Engineers no longer need to choose between performance and affordability; they can now have both."
Implications for Modern Engineering
- High-Speed Digital Communications: The 16-bit resolution and low jitter are essential for validating PAM4 and other multi-level signaling standards used in next-generation networking hardware.
- Quantum and Scientific Research: The ability to generate ultra-precise, repeatable waveforms is critical for controlling qubits and high-speed ion traps, where signal noise can lead to decoherence.
- Aerospace and Defense: The frequency-hopping capability and native IQ modulation allow for realistic emulation of complex threat environments, significantly reducing the time required to test radar and communication jamming equipment.
- Automotive Design: As vehicle-to-everything (V2X) communication becomes standard, the need for testing complex, wide-bandwidth signals has shifted from the lab to the production floor. The DG70000 provides the necessary bandwidth to simulate these vehicular RF environments.
