Detailed description
Technical data
Type of receiver:
Narrow band DCF77 quadrature receiver with automatic gain control, bandwidth: approx. 20Hz
Status info:
RF Signal: Indicated by LED, antenna alignment enhanced by utility program
Free running: Indicated by LED and utility program without RF signal the clock runs on quartz basis with an accuracy of ±1·10-6 (after 24 hours of synchronous operation)
Modulation: Indicated by LED and utility program
Reception Control:
Multiple check of received time telegram
Plausibility control by using two complete time telegrams
