LS3081B Signal Generator – Detailed Description
The LS3081B 3GHz Single Channel RF Analog Signal Generator is a high-precision instrument engineered for modern RF testing and laboratory applications. Part of Tabor Electronics’ Lucid series, the LS3081B provides ultra-low phase noise, fast frequency switching, and versatile analog and pulse modulation capabilities in a compact benchtop form factor.
Fast Frequency Switching for Efficient Testing
With a switching speed of under 100µs, the LS3081B minimizes downtime between frequency hops, allowing faster sweep rates and maximizing measurement throughput. This capability is critical in automated test equipment (ATE) environments, reducing testing costs while ensuring accurate, repeatable results.
Superior Signal Integrity
The LS3081B delivers a phase noise of -138 dBc/Hz at 1 GHz (10 kHz offset), ensuring clean, stable signals for precision measurements. This low noise performance supports high-demand applications such as local oscillator testing, intermodulation distortion measurements, and high-performance DAC/ADC clocking.
Versatile Modulation Capabilities
Engineered for a wide range of RF simulations, the LS3081B supports AM, FM, PM, Sweep, and Pulse modulation. Internal and external pulse modulation provides up to 60 dBc on/off ratio, enabling accurate radar, communications, and electronic warfare testing. Users can also modulate external baseband signals for custom waveform generation.
Flexible Control and Integration
The LS3081B uses industry-standard SCPI and VISA protocols for seamless integration into automated setups. Control is possible via LAN or USB, with compatibility for Python, MATLAB, C#/C++, and LabVIEW. The included virtual front panel provides intuitive local or remote operation, ideal for both field and lab testing.
Applications
The LS3081B is ideal for radar systems, communications device testing, high-precision lab measurements, and automated manufacturing environments. Its combination of speed, signal purity, and modularity makes it a trusted choice for RF engineers and test teams.
