Description
LSX4094B Signal Generator
The LSX4094B Signal Generator is a high performance 40 GHz four channel microwave signal source engineered for advanced RF system development and production testing. Built to support complex and synchronized signal generation, this benchtop instrument enables engineers to simulate, validate, and stress test modern microwave systems with precision and confidence.
With four independent yet coherent channels, the LSX4094B Signal Generator allows multi tone generation, phased array beamforming research, frequency translation experiments, and radar signal simulation within a single compact unit. This integrated architecture reduces system complexity while improving measurement accuracy and synchronization across channels.
Signal Integrity and Purity
Spectral purity is critical at high frequencies. The LSX4094B Signal Generator establishes a new benchmark in low phase noise performance. At a 10 kHz offset, phase noise reaches -148 dBc per Hz at 100 MHz, -133 dBc per Hz at 1 GHz, and -114 dBc per Hz at 10 GHz. Harmonics are maintained at -50 dBc and non harmonics at -90 dBc. This level of purity ensures stable local oscillator performance, accurate intermodulation distortion measurements, and reliable clocking for high speed DAC and ADC systems. Engineers working in radar, satellite communication, and defense applications can depend on clean and stable microwave output.
Fast Switching Performance
The LSX4094B Signal Generator supports frequency switching below 10 µs with coherent phase alignment across channels. Fast switching reduces idle time in automated manufacturing environments and increases overall test throughput. It also enables realistic frequency hopping simulation for electronic warfare systems, secure communication protocols, and pulse to pulse radar testing. Engineers can perform rapid measurements without sacrificing signal stability.
Modulation Capabilities
The LSX4094B Signal Generator includes built in AM, FM, PM, Sweep, and Pulse modulation. Frequency modulation supports deviations up to 10 MHz with rates up to 1 MHz. Amplitude modulation provides linear depth up to 90 percent with rates up to 100 kHz. Phase modulation allows peak deviation up to 360 degrees. Pulse modulation delivers a 70 dB on off ratio with rise and fall times below 15 ns. These features make the LSX4094B Signal Generator ideal for radar waveform generation, advanced communication system testing, and microwave research applications.
Control and Integration
The LSX4094B Signal Generator integrates smoothly into automated test systems using industry standard SCPI and VISA protocols. Connectivity options include LAN, USB, and SPI interfaces. It supports programming in Python, MATLAB, C, C++, C#, and LabVIEW environments. The virtual front panel provides intuitive graphical control for local or remote operation. This flexibility ensures seamless integration into laboratory, field, and production environments.
The LSX4094B Signal Generator combines four channel 40 GHz coverage, ultra low phase noise, and ultra fast switching to meet the most demanding RF and microwave challenges.
