Timecode
Principle of Operation
The GPS167 board is capable of generating IRIG, AFNOR and IEEE1344 standard
time codes. Apart from the digitally generated amplitude-modulated code, it also provi-
des the unmodulated DC-Level shift code. The modulated sine wave carrier and the
board´s internal time pattern are derived from the radio clock´s disciplined oscillator.
