TCO100 Time Code Generator

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. 

Features

  • Generates SMPTE, EBU, 30, 25 and 24 fps or IRIG-B (modulated and unmodulated) time codes
  • Functions as a backup time code source for master clock systems
  • Can be connected to a GPS500 master clock generator to automatically synchronize to GPS atomic clock time
  • Automatic Daylight Savings Time adjustment for North America and available for other countries
  • Temperature Compensated Crystal Oscillator (TCXO) provides accuracy of ±1 minute/year (<165 ms / day)
  • 6-digit red LED time or date display
  • All functions can be controlled via RS-232
  • -11.5 to +12 hour selectable Time Zone offsets in 30 minute increments

Specifications
