Product Specification LMS Series Lab Brick Synthesized Signal Generator Features/Benefits > Cost effective, fast switching signal generators to 2 GHz > Includes easy to use virtual front panel GUI program > Fast internal and external Pulse Modulation > Selectable internal/external 1 MHz reference > Phase Continuous Frequency Sweep (LFM) > Operates autonomously from an unsupervised USB power source or battery pack > Extremely Energy efficient design > Easily portable at less than 1 pound > Sized to fit into a single rack unit for ATE applications Overview The Lab Brick LMS series of synthesized signal generators bring affordability, functionality and simplicity to the microwave test bench. The LMS series covers from 4 GHz up to 2 GHz with 1 Hz frequency resolution, 1 us frequency switching and +1 dbm output with up to 5 db of output level control. They offer advanced features such as linear frequency sweeping, internal/external 1 MHz reference and optional pulse modulation. Each Lab Brick Signal Generator is shipped with a memory stick containing the easy to use Graphical User Interface (GUI). Simply plug the Lab Brick LMS Signal Generator into any USB port and open the GUI. Alternatively, for users wishing to develop their own interface, LabVIEW compatible drivers are available as well as a Windows API DLL file with an instruction manual. Every Lab Brick Signal Generator is also equipped with the autonomous operation feature. Autonomous mode allows the signal generator to operate in the absence of a USB host. Plug into a USB compatible power source to begin operation in a user defined state. Lab Brick Signal Generators are a fast, easy to use and cost-effective solution to your signal generation needs.
