Description
LSX1491D Microwave Generator
The LSX1491D 14GHz Single Channel Microwave Signal Generator Module delivers high-fidelity RF signals for demanding applications in lab, production, and field environments. Part of Tabor Electronics’ Lucid-X family, this generator combines speed, accuracy, and flexibility in a small footprint modular design, ensuring engineers and test teams can achieve precise, repeatable results.
Signal Integrity and Purity
The LSX1491D sets a benchmark in spectral purity. It provides ultra-low phase noise across its operating range, including -133 dBc/Hz at 1 GHz (10 kHz offset), -148 dBc/Hz at 100 MHz, and -114 dBc/Hz at 10 GHz. With harmonics at -50 dBc and spurious signals at -90 dBc, this generator guarantees clean, stable signals critical for high-precision measurements, Local Oscillators, DAC/ADC clocking, and intermodulation distortion testing.
Analog and Pulse Modulation
Equipped with advanced analog modulation capabilities, the LSX1491D supports AM, FM, PM, Sweep, and Pulse modulation. Frequency modulation provides deviations up to 10 MHz with rates up to 1 MHz. Amplitude modulation supports linear depth up to 90% at rates up to 100 kHz, while phase modulation offers a peak deviation of 360 degrees. The pulse modulation delivers a high on/off ratio (~70 dB) and ultra-fast rise/fall times under 15 ns, ideal for radar, electronic warfare, and secure communications testing.
Fast Frequency Switching
With switching speeds as fast as 10 µs, the LSX1491D reduces dead time during automated testing and allows rapid measurements in dynamic RF environments. It is perfect for simulating frequency-hopping radars, secure communications, and electronic warfare scenarios without sacrificing accuracy.
Flexible Control and Integration
Engineered for versatility, the LSX1491D supports SCPI and VISA protocols, enabling remote control via LAN, USB, or SPI interfaces. Integration with Python, MATLAB, C#/C++, and LabVIEW is seamless, while the included virtual front panel allows intuitive local operation. Its compact modular design accommodates desktop, benchtop, PXIe, rackmount, or portable applications.
Applications
The LSX1491D Microwave Generator is ideal for radar testing, electronic warfare, communication system simulation, automated test production, and high-precision laboratory experiments. Its combination of spectral purity, ultra-fast switching, and versatile modulation makes it an essential tool for RF engineers and researchers.
