Description
LSX1491B Signal Generator
The LSX1491B Signal Generator is a high performance 14 GHz single channel microwave signal source built for advanced RF and microwave environments. As part of the Lucid X platform, it combines ultra low phase noise, coherent frequency switching and rapid settling time in a compact modular design. Engineers working in radar development, electronic warfare simulation, quantum research and automated production testing benefit from its stability and speed.
Signal Integrity and Spectral Purity
Signal purity directly impacts measurement accuracy. The LSX1491B Signal Generator sets a high benchmark for spectral performance with phase noise of -148 dBc/Hz at 100 MHz, -133 dBc/Hz at 1 GHz and -114 dBc/Hz at 10 GHz at a 10 kHz offset. Harmonics are specified at -50 dBc and non harmonics at -90 dBc. This clean microwave output supports Local Oscillator applications, intermodulation distortion measurements and high performance DAC and ADC clocking. Engineers can rely on consistent and repeatable results even in the most demanding setups.
Ultra Fast Frequency Switching
The LSX1491B Signal Generator features switching speed below 10 µs with coherent frequency switching capability. This ultra fast performance reduces dead time in automated test systems and increases throughput in manufacturing environments. It also enables realistic simulation of frequency hopping radar systems, secure communication links and electronic warfare scenarios where signals must change pulse to pulse without compromising phase continuity.
Advanced Modulation Capabilities
The LSX1491B Signal Generator includes built in AM, FM, PM and Sweep modulation. FM supports deviation up to 10 MHz with modulation rates up to 1 MHz. AM offers linear depth up to 90 percent with rates up to 100 kHz. PM allows peak deviation up to 360 degrees. Pulse modulation provides a typical 70 dB on off ratio with rise and fall times under 15 ns. These features make it ideal for radar pulse simulation, analog communication testing and advanced microwave subsystem validation.
Control and Integration
The LSX1491B Signal Generator integrates smoothly into automated environments using SCPI and VISA standards. It supports LAN, USB and SPI interfaces, allowing control through Python, MATLAB, C, C++ and LabVIEW. A virtual front panel offers intuitive local and remote operation. With multiple form factors including PXIe, rackmount, benchtop, desktop and portable configurations, the instrument adapts easily to laboratory, field or embedded applications.
The LSX1491B Signal Generator delivers the performance, speed and spectral purity required for next generation microwave testing.
