Signal generator LSX4091X

microwaveRFsingle-channel

Overview
The Lucid-X LSX4091X is a compact, modular microwave signal generator available in multiple form factors (PXIe module, desktop/benchtop, rackmount, portable). It delivers very low phase noise and high spectral purity with single-channel frequency coverage up to 40 GHz. Interfaces include LAN, USB and SPI; remote control via SCPI/VISA is supported. The product targets demanding RF and microwave applications such as LO sources, radar, electronic warfare and high-performance DAC/ADC clocking.
