Description
LSX4091D Microwave Generator
The LSX4091D 40GHz Single Channel Microwave Signal Generator Module is a cutting-edge solution for engineers requiring ultra-high frequency and low-noise signals. Part of Tabor Electronics’ Lucid-X series, it offers unmatched performance in a compact, modular form factor suitable for laboratory, production, and field testing applications.
Signal Integrity and Spectral Purity
The LSX4091D sets a benchmark in signal fidelity, delivering exceptionally low phase noise: -148 dBc/Hz at 100 MHz, -133 dBc/Hz at 1 GHz, and -114 dBc/Hz at 10 GHz (10 kHz offset). Harmonics are maintained at -50 dBc and spurious signals at -90 dBc, ensuring clean, stable output crucial for Local Oscillators, high-performance DAC/ADC clocking, and intermodulation distortion measurements.
Advanced Modulation Capabilities
This microwave generator supports AM, FM, PM, Sweep, and Pulse modulation. Frequency Modulation (FM) achieves deviations up to 10 MHz at rates up to 1 MHz. Amplitude Modulation (AM) provides linear depth up to 90% at rates up to 100 kHz, and Phase Modulation (PM) reaches peak deviations of 360 degrees. Pulse modulation offers high on/off ratios (~70 dB) and ultra-fast rise/fall times under 15 ns, ideal for radar, electronic warfare, and secure communications testing.
Ultra-Fast Frequency Switching
With <10 µs switching speed, the LSX4091D dramatically reduces dead time during automated testing and accelerates measurement throughput. Its rapid switching also enables simulation of complex RF scenarios like frequency-hopping radars, electronic warfare threats, and secure military or commercial communication protocols, all without compromising accuracy.
Flexible Control and Integration
The LSX4091D supports industry-standard SCPI and VISA protocols for remote operation via LAN, USB, or SPI interfaces. It integrates easily with Python, MATLAB, C#/C++, and LabVIEW. The virtual front panel allows intuitive local control. Its modular design is available as Desktop, Benchtop, PXIe, Rackmount, or Portable, offering unparalleled flexibility for diverse testing environments.
Applications
This microwave signal generator is ideal for radar system testing, electronic warfare simulations, communication signal validation, and high-precision laboratory experiments. Its combination of high frequency, ultra-low noise, fast switching, and versatile modulation makes it a must-have for RF engineers and researchers.
