Vaunix has introduced an X-band signal generator to their Lab Brick product line. The LMS-123 operates from 8 GHz to 12 GHz, and offers low phase noise, fast 100 usec switching time, and fine 100 Hz frequency resolution. The LMS series also offers advanced operating features such as phase-continuous linear frequency sweeping, optional modulation formats, and internal/external triggering. Each Lab Brick signal generator measures 4.90 x 3.14 x 1.59 in. (124 x 80 x 40 mm) and weighs less than 1 lb. (0.45 kg). They connect to a host computer by means of a standard USB cable and are controlled via the Graphical User Interface (GUI) software supplied with each unit. The simple GUI features large display windows to quickly view and adjust the signal generator's operating parameters. They are powered and controlled by means of any USB equipped personal computer (PC) or laptop. They can also be run from battery power or from a remote power supply for non-USB embedded or automated applications.
