Description
LSX4091R 40GHz Rack
The LSX4091R 40GHz Single Channel Microwave Signal Generator delivers precision, flexibility, and compact performance in a 1U, 19” rack-mounted form factor. Designed for high-end RF and microwave applications, it provides a single channel with ultra-low phase noise, fast frequency switching, and versatile modulation capabilities suitable for radar, secure communications, and automated testing systems.
Signal Integrity and Low Phase Noise
The LSX4091R sets the benchmark in spectral purity, offering phase noise of -133 dBc/Hz at 1 GHz with a 10 kHz offset. Harmonics remain at -50 dBc and non-harmonics at -90 dBc, ensuring clean, high-fidelity signal output. This precision allows engineers to perform critical measurements without signal degradation.
Ultra-Fast Frequency Switching
With frequency switching under 10 µs, the LSX4091R minimizes dead time in automated testing, improving efficiency and reducing costs. Fast switching is essential for simulating frequency-hopping radar, electronic warfare, and secure communication systems where signals change pulse-to-pulse.
Versatile Modulation Options
Equipped with AM, FM, PM, Sweep, and Pulse modulation, the LSX4091R offers comprehensive signal generation capabilities. FM supports deviations up to 10 MHz at rates up to 1 MHz, AM provides up to 90% linear depth at 100 kHz, and PM offers up to 360° deviation. Pulse modulation ensures a high on/off ratio (~70 dB) with rise/fall times under 15 ns, suitable for radar and electronic warfare applications.
Seamless Control and Integration
The LSX4091R supports SCPI and VISA commands over LAN, USB, or SPI interfaces, allowing integration with Python, MATLAB, C#/C++, and LabVIEW. The virtual front panel offers an intuitive interface for both local and remote control, streamlining lab and field operations.
The LSX4091R 40GHz Rack combines single-channel precision, low phase noise, ultra-fast switching, and versatile modulation in a space-efficient rack format, making it ideal for modern RF and microwave laboratories.
