The USB SOURCE (USB-S) consists of a  family of pocket-sized highly stable comb generator with a single comb frequency.  Powered by an external standard USB connector.  Individual units available with frequencies of 1.8 MHz, 10 MHz, 64 MHz, 100 MHz, 133 MHz and 200 MHz.  Custom frequencies are available, consult AET Sales for this option.   An option is available to pulse the comb signal on/off at a slow rate to allow testing of receiver quasi-static detectors.  The pulsed mode works for any comb frequency selected.
