SSG5000A Series Attenuator ( SSG5080A-LP )

The SSG5080A-LP option is an upgrade for the Siglent SSG5080A RF Signal Generator, designed to deliver ultra-low phase noise performance. By enabling this option, the instrument achieves superior signal purity, reducing spurious and phase noise levels significantly. This makes it ideal for demanding test scenarios where clean, stable signals are critical. When activated, the SSG5080A-LP optimizes the internal synthesizer architecture and clock distribution to reduce jitter and noise contributions. Engineers benefit from high spectral purity across the entire frequency range, enabling accurate and repeatable measurements.

Key Features

• Enhanced Phase Noise Performance

  • Improves close-in phase noise performance (typically -133 dBc/Hz @ 1 GHz, 10 kHz offset).

  • Ideal for applications where phase noise is the limiting factor.

• Wide Frequency Coverage

  • Covers up to 8.5 GHz, suitable for microwave, RF, and communication system testing.

• Better Measurement Confidence

  • Cleaner signals reduce uncertainty in phase-sensitive tests such as demodulation, jitter analysis, and system sensitivity verification.

• Easy Activation

  • Delivered as a software license option, enabling flexibility based on application requirements.

Typical Applications

1. Radar System Testing

Low phase noise is critical in radar systems, where poor spectral purity leads to reduced detection accuracy. With the LP option, engineers can simulate clean RF signals that match the requirements of modern high-resolution radars.

2. Telecommunication & Wireless Research

For 5G, satellite, or advanced wireless communications, the LP option ensures that carrier signals used in sensitivity testing or receiver blocking tests do not introduce excess noise. This makes results more reliable in base station, satellite ground station, or UE validation.

3. High-Performance Oscillator and PLL Characterization

The LP option enables precise characterization of oscillators, frequency synthesizers, and PLLs. Engineers can evaluate DUT performance without the generator’s noise dominating the measurement.

4. Quantum Computing & Physics Experiments

Quantum systems are extremely phase noise sensitive. The LP option provides the clean signals needed to manipulate and probe qubits, cavities, and high-Q resonators.

5. Military & Aerospace

Applications in navigation, avionics, and secure communications often require ultra-clean signals to maintain precision and avoid signal degradation. The LP option ensures compliance with stringent performance requirements.
