Description
LSX1491X Single PXIe
The LSX1491X Single PXIe Microwave Signal Generator delivers exceptional performance for microwave and RF testing with a 14GHz single-channel PXIe module. Combining high spectral purity, low phase noise, ultra-fast frequency switching, and versatile modulation, it meets the rigorous demands of modern RF applications, including radar, electronic warfare, and secure communications.
Signal Integrity and Precision
The LSX1491X guarantees superior signal integrity across its entire frequency range. It achieves low phase noise performance of -133 dBc/Hz at 1 GHz (10 kHz offset), with harmonics at -50 dBc and non-harmonics at -90 dBc. Coherent operation ensures precise phase alignment, supporting high-performance DAC/ADC clocking and critical RF measurement systems.
Fast Frequency Switching for Advanced Testing
With frequency switching under 10 µs, the LSX1491X reduces dead time in automated testing, improving throughput and efficiency. This rapid switching is essential for simulating real-world scenarios such as frequency-hopping radars, electronic warfare threats, and secure communication systems where pulse-to-pulse frequency changes are required.
Advanced Modulation Capabilities
The LSX1491X supports AM, FM, PM, Sweep, and Pulse modulation, providing versatile signal simulation for analog and RF communications. Frequency Modulation (FM) allows deviations up to 10 MHz at rates up to 1 MHz. Amplitude Modulation (AM) reaches linear depths of up to 90% at rates up to 100 kHz, while Phase Modulation (PM) offers peak deviations of 360°. Pulse modulation features fast rise/fall times (<15 ns) and a high on/off ratio (~70 dB), ensuring precise radar and electronic warfare applications.
Flexible Control and Programming
The LSX1491X integrates seamlessly with SCPI and VISA protocols over LAN, USB, or SPI interfaces. Compatibility with Python, MATLAB, C#/C++, and LabVIEW allows easy automation. The included virtual front panel provides intuitive local and network control for efficient testing and development.
The LSX1491X Single PXIe Generator combines ultra-high precision, low phase noise, rapid switching, and versatile modulation in a compact PXIe module, making it the perfect solution for advanced RF and microwave testing.
