Description
LS3081R Signal Generator
The LS3081R Signal Generator is a high performance 3 GHz single channel RF signal source engineered for reliable laboratory testing and automated production environments. Designed as a compact 19 inch 1U rack module, it provides outstanding signal purity, fast switching capability, and flexible modulation features in a space efficient format. For engineers seeking stable RF output with seamless system integration, the LS3081R Signal Generator offers an ideal balance between precision and practicality.
Operating up to 3 GHz, the LS3081R Signal Generator supports a wide range of RF applications including component characterization, receiver testing, mixer validation, and communication system development. Its rack mount design makes it particularly suitable for automated test equipment systems where space efficiency and performance consistency are critical.
Fast Switching Performance
The LS3081R Signal Generator supports frequency switching below 100 µs, significantly reducing settling time between frequency hops. In production environments, this minimizes dead time and increases overall throughput. Faster switching enables quicker sweep rates and improved measurement efficiency. Whether used on a design bench or integrated into a high volume automated test system, the LS3081R Signal Generator ensures rapid and repeatable performance.
Signal Integrity
Signal purity is essential in modern RF testing. The LS3081R Signal Generator delivers a typical single sideband phase noise of -138 dBc per Hz at 1 GHz with a 10 kHz offset. This low noise floor ensures clean and stable output, which is critical for high precision measurements and sensitive RF component evaluation. Engineers can rely on the LS3081R Signal Generator to provide accurate and repeatable results without unwanted spectral interference.
Modulation Capabilities
The LS3081R Signal Generator includes built in AM, FM, PM, and Sweep modulation starting from 100 MHz up to the maximum frequency range. It also supports external baseband modulation for advanced signal simulation. Pulse modulation can be applied internally or externally, with an on off ratio of 60 dBc. These modulation capabilities make the LS3081R Signal Generator suitable for analog communication system testing and RF signal simulation tasks.
Control and Integration
The LS3081R Signal Generator utilizes industry standard SCPI and VISA architecture for seamless remote control. It connects via LAN and USB interfaces and supports programming in Python, MATLAB, C, C++, C#, and LabVIEW environments. The included virtual front panel provides intuitive graphical control for local or remote operation. Optional emulator packages support integration into existing test setups, reducing transition time and improving workflow efficiency.
The LS3081R Signal Generator combines compact rack integration, reliable RF output, and flexible control to meet modern testing demands.
