PZF180: DCF77 Correlation Receiver (Eurocard)


High accuracy DCF77 correlation receiver for generation of standard frequencies and pulses

Key Features

Warranty Period (Years): 3 RoHS-compliant



Product Description

By evaluating the pseudo-random sequence (PZF), which is part of the DCF77 signal in addition to the amplitude modulation, the PZF180 is capable to reproduce a time pattern in the range of microseconds. This allows generation of high precision pulses and an accurate adjustment of the main oscillator of the system. Besides various standard frequencies, the board provides a programmable frequency output. Additional features of PZF180 are pulses per second (PPS) and per minute (PPM), four RS232 interfaces and IRIG timecode outputs.


Characteristics

Receiver Type Two seperate receiver channels for signal conversion and best aquisition and tracking of the DCF77 signal (AM + PZF).
Status Indicators Indication of a DCF-signal with at least minimum field strength by 'Feld'-LED
