Description
LS1291B Signal Generator
The LS1291B 12 GHz Single Channel RF Analog Signal Generator delivers precision microwave signal generation for lab, production, and field testing. As part of the Lucid series, it combines ultra-clean signal fidelity, rapid switching performance, and broad modulation support in a compact, modular instrument. This makes it an excellent choice for engineers working on communications systems, radar validation, aerospace research, and automated validation environments.
Signal Integrity and Noise
Signal quality is critical in high-frequency testing. The LS1291B Signal Generator features low phase noise of -138 dBc/Hz at 1 GHz with a 10 kHz offset, ensuring exceptionally clean RF output. This helps deliver reliable measurements for intermodulation distortion testing, local oscillator calibration, and high-precision RF analysis. Its stable output ensures repeatable results across a variety of measurement scenarios.
Fast Frequency Switching
The LS1291B Signal Generator offers frequency switching in less than 100 µs. This rapid switching reduces “dead time” between frequency changes, enabling faster sweep rates and higher throughput in automated test setups. Whether in design bench validation or mass production, fast switching helps accelerate test cycles and improve operational efficiency without sacrificing signal accuracy.
Versatile Modulation
Equipped with a full suite of analog modulation options, the LS1291B supports AM, FM, PM, Sweep, and Pulse modulation. Pulse modulation delivers a 60 dBc on/off ratio, while FM and PM options allow flexible signal shaping for communications and radar simulations. External baseband modulation further enhances versatility, enabling tailored signal scenarios for complex testing requirements.
Control and Integration
This signal generator supports SCPI and VISA standards for seamless remote control. Engineers can integrate it into test automation frameworks via LAN or USB using Python, MATLAB, C#/C++, or LabVIEW. A virtual front panel provides intuitive local control, while network connectivity allows efficient remote operation, making it suitable for diverse testing environments.
Applications
The LS1291B Signal Generator is ideal for RF subsystem evaluation, radar system testing, communication link validation, and automated test environments. Its combination of speed, fidelity, and modulation flexibility makes it a dependable tool for advanced RF and microwave work.
