USB Sources Generate 6 GHz

The Lab Brick family of USB-compatible signal generators from Vaunix Technology Corp. will be on display at the 2009 Boston MTT-S Exhibition, with five models covering a total range of 50 MHz to 6 GHz. The signal generators are controlled by the USB port of a laptop or personal computer running easy-to-use Graphical User Interface (GUI) software. Output levels can be adjusted via the GUI software over a control range of 50 dB (-40 to +10 dBm) for the 6-GHz model and 55 dB (-45 to +10 dBm) for the other four models. Output-level settings are accurate within +1.5 dB and -0.5 dB. Frequency can be set with 100-kHz resolution, with initial accuracy (before aging) of better than 2 PPM. The phase noise for the 6-GHz model is typically -95 dBc/Hz offset 100 kHz from the carrier, with typical harmonics of -10 dBc and typical spurious of -80 dBc.
