Description
LSX4091P Portable Signal Generator
The LSX4091P 20GHz Single Channel Portable Microwave Signal Generator is a precision instrument designed to meet the demands of advanced RF and microwave testing. Part of Tabor Electronics’ Lucid-X series, the LSX4091P delivers ultra-low phase noise, ultra-fast frequency switching, and a full suite of analog and pulse modulation options, making it indispensable for engineers performing high-precision RF work in both lab and field environments.
Ultra-Fast Frequency Switching
The LSX4091P features an ultra-fast frequency switching speed of less than 10µs, reducing “dead time” during automated tests and enabling faster, more efficient measurement cycles. This capability is critical for frequency-hopping radar simulations, electronic warfare applications, and secure communications testing, where signals must change pulse-to-pulse without losing accuracy.
Exceptional Signal Integrity
With phase noise of -133 dBc/Hz at 1 GHz (10 kHz offset) and harmonics suppressed to -50 dBc, the LSX4091P ensures exceptional signal purity. Its low noise floor is ideal for local oscillator applications, intermodulation distortion measurements, and high-performance DAC/ADC clocking, providing precision and reliability for demanding RF experiments.
Versatile Modulation Capabilities
The LSX4091P supports AM, FM, PM, Sweep, and Pulse modulation, allowing engineers to simulate complex analog communication systems. Pulse modulation delivers high on/off ratios (typically 70 dB) with rise/fall times under 15 ns, perfect for radar and electronic warfare testing. Both internal and external modulation options provide maximum flexibility for waveform generation.
Flexible Control and Connectivity
Designed for integration and ease of use, the LSX4091P uses SCPI and VISA commands, supporting LAN, USB, and SPI interfaces. It is compatible with Python, MATLAB, C#/C++, and LabVIEW. A virtual front panel allows intuitive local or remote control, making this portable generator ideal for both field and lab use.
Applications
The LSX4091P is ideal for radar system evaluation, electronic warfare, secure communication testing, automated lab measurements, and any application requiring precise, high-fidelity microwave signals. Its combination of speed, signal purity, and portability makes it a leading choice for advanced RF engineers.
