Description
LSX4091B Signal Generator
The LSX4091B Signal Generator is a high performance 40 GHz single channel microwave signal source engineered for cutting edge RF and microwave applications. Designed for engineers who demand extended frequency range and superior signal purity, this benchtop instrument combines low phase noise, ultra fast switching, and flexible modulation features in a compact and scalable platform.
With frequency coverage up to 40 GHz, the LSX4091B Signal Generator is ideal for advanced radar research, aerospace validation, satellite communication testing, and electronic warfare simulation. Its modular Lucid X architecture allows deployment in benchtop, rackmount, desktop, PXIe, or portable configurations, giving laboratories and production environments maximum flexibility.
Signal Integrity
Signal integrity is essential at millimeter wave frequencies. The LSX4091B Signal Generator delivers excellent phase noise performance with -148 dBc/Hz at 100 MHz, -133 dBc/Hz at 1 GHz, and -114 dBc/Hz at 10 GHz at 10 kHz offset. Harmonics are maintained at -50 dBc and non harmonics are below -90 dBc. This ensures clean and stable output for local oscillator applications, intermodulation distortion measurements, and high performance DAC and ADC clocking systems. Engineers can trust the LSX4091B Signal Generator to provide repeatable and accurate results in demanding test setups.
Fast Frequency Switching
The LSX4091B Signal Generator supports frequency switching below 10 µs with coherent phase continuity. This reduces idle time during automated testing and increases production throughput. It also enables realistic frequency hopping simulations for secure communications, radar pulse to pulse testing, and electronic warfare scenarios. Fast switching allows precise measurement without compromising stability.
Analog and Pulse Modulation
The LSX4091B Signal Generator includes built in AM, FM, PM, and Sweep modulation. Frequency modulation supports deviations up to 10 MHz with rates up to 1 MHz. Amplitude modulation provides linear depth up to 90 percent with rates up to 100 kHz. Phase modulation supports peak deviation up to 360 degrees. Pulse modulation delivers a 70 dB on off ratio with rise and fall times below 15 ns. These capabilities make it highly suitable for radar pulse testing and complex microwave signal simulation.
Control and Integration
The LSX4091B Signal Generator integrates seamlessly into automated systems using SCPI and VISA architecture. It connects via LAN, USB, and SPI interfaces and supports programming in Python, MATLAB, C, C++, C#, and LabVIEW. The virtual front panel enables intuitive local and remote operation. This flexibility ensures smooth integration into laboratory and field environments.
The LSX4091B Signal Generator combines 40 GHz frequency coverage, excellent spectral purity, and ultra fast switching to meet the most demanding microwave testing requirements.
