IMS-PZF: PZF (DCF77) Correlation Receiver (Eurocard)
Key Features
- High accuracy DCF77 correlation receiver for generation of standard frequencies and pulses
Oscillator Options: OCXO-SQ, OCXO-MQ, OCXO-HQ - Pulses per second and per minute
- RS-232 interface
Product Description
By evaluating the pseudo-random sequence (PZF), which is part of the DCF77 signal in addition to the amplitude modulation, the PZF clock 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 IMS-PZF clock are pulses per second (PPS) and per minute (PPM) and IRIG timecode outputs.

Switch outputs | Four TTL outputs can configured independently for the following modes: - free programmable cyclic or fixed impulses - timecode - timer mode; three 'ON'- and three 'OFF'-states can be setup per day The switch states can be inverted for all three outputs, the impulse lengths are configurable. The impulse output can be configured for all channels together to 'always' or 'ifsync'. |
