Description
LSX2091B Signal Generator
The LSX2091B Signal Generator is a high performance 20 GHz single channel microwave signal source designed for modern RF and microwave testing environments. As part of the Lucid-X platform, it combines low phase noise, ultra fast switching speed, and flexible modulation capabilities in a compact benchtop design. Engineers working in radar development, aerospace systems, electronic warfare, and advanced laboratory research rely on this instrument for precise and repeatable signal generation.
Signal Integrity
Signal purity is essential in high frequency applications. The LSX2091B 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, all measured at 10 kHz offset. Harmonics are controlled at -50 dBc and non harmonics remain below -90 dBc. This level of spectral purity ensures accurate measurements in local oscillator applications, intermodulation distortion testing, and high performance DAC and ADC clocking systems.
Fast Frequency Switching
The LSX2091B Signal Generator supports ultra fast frequency switching below 10 µs with coherent phase continuity. This minimizes dead time during automated production testing and increases throughput. It also enables realistic simulation of frequency hopping radar systems, secure military communications, and electronic warfare scenarios. Engineers can perform rapid measurements without sacrificing accuracy or stability.
Analog and Pulse Modulation
This 20 GHz microwave signal generator offers versatile built in modulation capabilities. FM supports deviation up to 10 MHz with rates up to 1 MHz. AM provides linear depth up to 90 percent with rates up to 100 kHz. PM offers peak deviation up to 360 degrees. Pulse modulation achieves a high 70 dB on off ratio with rise and fall times under 15 ns, making it ideal for radar pulse testing and advanced microwave simulations.
Control and Integration
The LSX2091B Signal Generator integrates easily into automated test systems. It supports SCPI and VISA standards and connects via LAN, USB, or SPI interfaces. Engineers can program the instrument using Python, MATLAB, C, C++, C#, or LabVIEW. The included virtual front panel provides intuitive local or remote control. Multiple form factors including PXIe, rackmount, desktop, and portable configurations allow flexible deployment in laboratory or field environments.
The LSX2091B Signal Generator combines high frequency coverage, low phase noise, and ultra fast switching to deliver dependable performance in demanding microwave applications.
