The TCO100 is a stabilized oscillator that generates IRIG-B, SMPTE or EBU TIME CODES. Although the TCO100 is designed to work primarily as a companion to the GPS500 master clock generator/receiver, it will function as a high-quality stand-alone source of accurate time code. When combined with a GPS500, the TCO100 will deliver precise time and date information virtually anywhere in the world. When operating as a stand-alone oscillator/time-code generator, the internal clock can be set with front panel switches or via RS232 control and will maintain stable time and frequency for long periods of time without further intervention or calibration.
