PZF600: DCF77 Correlation Receiver (Eurocard)

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

Key Features

Years of warranty: 2 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 PZF600 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 PZF600 are pulses per second (PPS) and per minute (PPM), four RS232 interfaces and IRIG timecode outputs.
