The SIGLENT SDG8004A is a premium 4-channel arbitrary waveform generator designed for advanced multi-channel applications. Each channel delivers up to 5 GHz output frequency at 12 GSa/s sampling rate with 16-bit resolution and independent control.

With inter-channel skew below 15 ps and powerful channel coupling, tracking, and combine functions, the SDG8004A excels in MIMO, phased-array, and multi-device synchronization tasks. It offers up to 4 Gpts memory per channel for complex, long-duration waveforms.

Built-in features include multi-pulse, multi-tone, chirp, PRBS, and extensive modulation options. This makes the SDG8004A the perfect solution for 5G/6G, high-speed serial (PCIe, 800G), radar, and quantum research applications.

Siglent SDG8004A 4CH AWG up to 5 GHz and 12 GSa/s sampling rate.

The SIGLENT SDG8004A is a high-performance 4-channel Arbitrary Waveform Generator designed for engineers and researchers who need to generate complex, high-fidelity signals with exceptional precision and flexibility.

It transforms how you create and control waveforms by combining ultra-high bandwidth (up to 5 GHz), massive memory (up to 4 Gpts per channel), and four fully independent output channels. Whether you are developing next-generation wireless systems, validating high-speed serial interfaces, or simulating realistic radar scenarios, the SDG8004A gives you the power to generate exactly the signals you need — with the timing accuracy, amplitude control, and channel synchronization that modern applications demand.

This instrument is intended for professionals working in advanced electronics, communications, aerospace, automotive, semiconductor, and research laboratories. It is especially valuable for engineers who require multi-channel signal generation with precise phase relationships, long-duration waveform playback, and advanced sequencing capabilities.

The benefits are clear: you can simulate real-world conditions with unprecedented realism, reduce development time through flexible multi-channel testing, and achieve higher measurement confidence thanks to the instrument’s exceptional signal fidelity and stability. The SDG8004A is not just a signal generator — it is a complete signal creation platform that helps you push the boundaries of what is possible in your field.

Engineered for the Most Demanding Signal Applications

The SIGLENT SDG8002A delivers exceptional performance in a compact 2-channel configuration. Whether you're developing next-generation 5G components, characterizing high-speed serial links, or performing advanced radar and EW testing, this instrument provides the signal integrity and flexibility you need.

Built on SIGLENT's advanced TrueArb and EasyPulse technologies, the SDG8002A generates low-jitter arbitrary waveforms point-by-point at sampling rates from 100 Sa/s to 12 GSa/s without compromising waveform detail. The 16-bit vertical resolution ensures precise amplitude control, while the massive 4 Gpts (optional) memory per channel enables long, complex sequence playback — up to 800 ms at full sampling rate.
