Description
LS1294B Signal Generator
The LS1294B Signal Generator is a 12 GHz four channel RF analog signal source engineered for high performance laboratory research, radar development, phased array testing and automated production systems. As part of the Lucid series, it provides outstanding signal fidelity in a compact and flexible modular design. With four independent RF channels, engineers can generate complex multi tone signals, perform mixer characterization and support phase coherent applications without the need for multiple standalone instruments.
Signal Integrity and Purity
Signal accuracy is critical in high frequency environments. The LS1294B Signal Generator offers excellent single sideband phase noise performance of -138 dBc/Hz at 1 GHz with a 10 kHz offset. This ensures exceptionally clean spectral output and minimizes measurement uncertainty. Whether validating RF front ends, testing local oscillators or analyzing sensitive communication modules, the LS1294B provides reliable and repeatable results across the full frequency range up to 12 GHz.
Fast Frequency Switching
Test speed directly impacts productivity. The LS1294B Signal Generator supports frequency switching below 100 µs, significantly reducing settling time between frequency hops. This capability improves sweep rates and minimizes idle time in automated test equipment environments. Engineers working with frequency agile radar systems or communication protocols benefit from higher throughput and efficient validation cycles.
Multi Channel Flexibility
With four channels in one platform, the LS1294B Signal Generator simplifies complex RF setups. It supports AM, FM, PM, Sweep and Pulse modulation starting from 100 MHz to the maximum frequency range. Pulse modulation offers a 60 dBc on off ratio and can be applied internally or externally. Multi channel synchronization supports advanced applications such as phased array antenna testing, quantum research setups and intermodulation distortion analysis.
Control and Integration
The LS1294B Signal Generator integrates easily into automated systems using SCPI and VISA standards over LAN or USB. It supports programming environments such as Python, MATLAB, C, C++ and LabVIEW. A virtual front panel enables intuitive graphical control locally or remotely. For embedded systems, the desktop configuration supports SPI and USB interfaces, adding further flexibility.
The LS1294B Signal Generator provides a scalable and cost effective solution for engineers who require synchronized four channel RF performance with low phase noise and fast switching.
