Description
LSX8081R 8GHz Signal Generator
The LSX8081R 8GHz Signal Generator is a precision engineered microwave source designed for engineers who demand clean signals, fast response, and reliable performance. Built as a 19 inch 1U rackmount unit, it offers a space saving solution without sacrificing microwave capability. With frequency coverage up to 8 GHz, this single channel instrument supports advanced RF and microwave applications across research, development, and manufacturing environments.
Signal Integrity and Purity
Signal purity is critical in high frequency systems. The LSX8081R 8GHz Signal Generator sets a strong benchmark with low phase noise performance of -133 dBc per Hz at 1 GHz with a 10 kHz offset. At 100 MHz, phase noise reaches -148 dBc per Hz, and at 10 GHz it achieves -114 dBc per Hz. Harmonics are specified at -50 dBc and non harmonics at -90 dBc, ensuring clean output for demanding microwave testing.
This level of spectral performance makes the LSX8081R 8GHz Signal Generator ideal for local oscillator applications, intermodulation distortion measurements, radar STALO systems, and high performance DAC and ADC clocking. Engineers can rely on stable frequency output and minimal interference during sensitive measurements.
Fast Switching Performance
The LSX8081R 8GHz Signal Generator features ultra fast frequency switching below 10 µs with coherent frequency transitions. In automated production systems, this reduces idle time between frequency steps and increases overall throughput. It also enables realistic simulation of frequency hopping radars, electronic warfare scenarios, and secure communication systems where signals must change rapidly between pulses.
Fast switching allows engineers to perform high speed measurements without compromising signal accuracy or stability.
Modulation Capabilities
Versatile modulation is a core strength of the LSX8081R 8GHz Signal Generator. It includes built in AM, FM, PM, and Sweep functions for analog signal simulation.
- FM deviation up to 10 MHz with rates up to 1 MHz
- AM depth up to 90 percent with rates up to 100 kHz
- PM deviation up to 360 degrees
- Pulse modulation with typical 70 dB on off ratio
- Rise and fall times under 15 ns
These features make the LSX8081R 8GHz Signal Generator highly suitable for radar pulse testing, electronic warfare validation, and analog communication system development.
Control and Integration
The LSX8081R 8GHz Signal Generator is built for seamless system integration. It supports industry standard SCPI and VISA command architecture for remote control. LAN, USB, and SPI interfaces allow flexible connectivity in both laboratory and automated test setups.
It integrates smoothly with Python, MATLAB, C, C++, C#, and NI LabVIEW environments. The included virtual front panel offers intuitive graphical control for both local and network operation, simplifying setup and configuration.
With its combination of compact design, microwave frequency coverage, fast switching, and advanced modulation, the LSX8081R 8GHz Signal Generator provides a powerful and dependable solution for modern RF and microwave testing.
