The Lab Brick LMS Signal Generators operate from 0.5 MHz to 20 GHz with low phase noise, fast 100 microsecond switching time, frequency resolution of 100 Hz. The generators are powered and controlled via USB and offer advanced features such as phase continuous linear frequency sweeping, internal/external 10 MHz reference, and optional pulse modulation. The GUI software provided can track and control several connected signal generators, simplifying multiple-signal test setups. Each device stores settings in internal memory, allowing it to power up in a specific instrument state. The signal generators are compact.
