Description
LS1291R 12GHz Signal Generator
The LS1291R 12GHz Signal Generator is engineered for engineers who require accurate, stable, and clean RF signals across a wide microwave frequency range. Designed as a 19 inch 1U rack module, it delivers professional grade performance in a compact footprint. With frequency coverage up to 12 GHz, this single channel instrument supports demanding laboratory, research, and production applications.
From design validation to high volume automated testing, the LS1291R 12GHz Signal Generator provides reliable signal generation with fast switching and excellent spectral purity. Its modular Lucid platform ensures flexibility while maintaining a small footprint that conserves valuable rack space.
Fast Switching Performance
Speed is critical in modern RF environments. The LS1291R 12GHz Signal Generator features frequency switching below 100 µs. This minimizes settling time between frequency steps and reduces overall test cycle duration.
In automated test equipment systems, faster switching translates directly into higher throughput and lower operational costs. Engineers can perform rapid sweeps and frequency hopping measurements without compromising stability or accuracy.
Signal Integrity and Purity
Signal clarity is essential for high precision measurements. The LS1291R 12GHz Signal Generator delivers a typical single sideband phase noise of -138 dBc per Hz at 1 GHz with a 10 kHz offset. This low noise floor ensures clean RF output and minimizes interference in sensitive test setups.
Whether used for radar local oscillator development, intermodulation distortion testing, or RF component characterization, the LS1291R 12GHz Signal Generator provides dependable and repeatable results. Its stable frequency output supports accurate analysis in high performance microwave systems.
Modulation Capabilities
The LS1291R 12GHz Signal Generator supports a comprehensive range of internal modulation schemes. Built in AM, FM, and PM are available from 100 MHz up to the maximum 12 GHz frequency range. Sweep functionality allows controlled frequency variation for response analysis.
Pulse modulation can be applied internally or through external baseband signals with an on off ratio of 60 dBc. Optional pulse and pattern generator features further expand the instrument’s capabilities, enabling more advanced simulation scenarios.
These modulation options make the LS1291R 12GHz Signal Generator suitable for analog communication testing, radar pulse analysis, and RF subsystem validation.
Control and Integration
The LS1291R 12GHz Signal Generator is built for seamless integration into laboratory and automated systems. It supports industry standard SCPI and VISA command architecture, allowing reliable remote control via LAN or USB interfaces.
Engineers can program the instrument using Python, MATLAB, C, C++, C#, or NI LabVIEW. The included virtual front panel provides intuitive graphical control for local and remote operation, simplifying setup and reducing development time.
With its wide frequency coverage, fast switching, low phase noise, and advanced modulation, the LS1291R 12GHz Signal Generator delivers a powerful and efficient solution for modern RF and microwave testing.
