The Lab Brick LMS series of Signal Generators bring affordability, functionality, reliability andsimplicity to the microwave test bench. The LMS products range from 0.5 MHz to 20 GHz with
100 Hz step size, 0.5 dB power control steps and linear frequency sweep capability.
Lab Bricks use a native USB HID interface to avoid the difficulties inherent in using older serial
or IEEE-488 interfaces implemented over USB. As a result, Lab Brick users can get to work
faster without having to install kernel level drivers, and Lab Brick devices can be easily used on
any system that supports USB HID devices, including low cost embedded computers using
Linux or similar operating systems.
The LMS-163 is a simple to use and affordable Signal Generator. The LMS-163 provides
calibrated power control from 8 to 16 GHz with a 100 Hz frequency setting resolution. The signal
generator is easily programmable for fixed frequency operation, unidirectional or bidirectionalfrequency sweep and pulse modulation directly from the included Graphical User Interface(GUI). Alternatively, for users wishing to develop their own interface, Vaunix supplies LabVIEWdrivers, Windows API DLL files, Linux drivers, Python examples and much more.
