Product Introduction

The SSG6M80A series is a multi-channel phase-coherent analog signal generator available in dual-channel and four-channel models, covering frequencies from 9 kHz to 20 GHz. By sharing a high-stability master clock and trigger system, it delivers true inter-channel phase coherence with independent control of frequency, amplitude, and phase on each channel, along with excellent long-term phase stability and a phase-memory function. Featuring ultra-low phase noise, wide output power range, high signal purity, and flexible modulation capabilities, the SSG6M80A is designed for demanding applications such as beamforming, phased-array systems, MIMO testing, differential signal generation, and multi-tone measurements.

Key Features

  • Frequency up to 13.6 GHz/20 GHz

  • 0.001 Hz frequency setting resolution

  • Level setting range from -110 dBm to +25 dBm

  • Phase noise: -135 dBc/Hz @ 1 GHz, 10 kHz offset (typ.)

  • Standard OCXO and FM/PM analog modulation

  • Independently adjustable frequency, amplitude and phase per channel

  • Multi-channel stable phase coherence (intra / inter-device), phase memory function

Product advantage

Multi-Channel Stable Phase Coherence

Traditional single-channel generators struggle to maintain consistent phase relationships when multiple signals are required. The SSG6M80A addresses this challenge by integrating multiple channels in a single instrument that share a common high-stability clock reference and trigger system. This architecture enables true inter-channel phase coherence while still allowing independent control of frequency, amplitude, and phase on each channel. Phase drift between channels remains below ±1.5° over 10 hours across the full bandwidth under typical laboratory temperature conditions, ensuring phase stability for long-duration testing.

Phase Memory Function

The SSG6M80A delivers excellent long-term phase stability and includes a phase-memory function that restores the original phase state after frequency changes. Multiple units can also be synchronized by connecting the master’s 10 MHz and 1 GHz reference outputs to the corresponding inputs on the slave units, expanding the channel count for larger test systems. These capabilities make the SSG6M80A particularly suitable for beamforming, phased-array evaluation, MIMO testing, differential signal generation, and multi-tone measurements.

Excellent SSB Phase Noise

Phase noise is typically below –135 dBc/Hz at a 1 GHz carrier with a 10 kHz offset. Combined with excellent harmonic and spurious suppression, the generators produce clean signals suitable for high-sensitivity receiver testing and high-linearity component characterization.

Wide Output Power Range

The SSG6M80A delivers excellent power output performance, supporting a wide output range from –110 dBm to +25 dBm while maintaining high output power across the entire frequency range. Typical level accuracy is below 0.7 dB, and standard power meter control enables closed-loop leveling, automatic cable-loss compensation, and flatness correction, ensuring accurate and repeatable power delivery in multi-port and wide-dynamic-range test setups.

Flexible Modulation Capability

The SSG6M80A supports FM and PM analog modulation with internal, external, or combined modulation sources. Optional pulse modulation and a pulse-train generator allow users to create single, double, or fully customized pulse sequences with adjustable width, period, and repetition counts, as well as flexible step or list sweeps supporting up to 65,535 points.
