11.8.9 PZF Clock
Receiver:
High accuracy DCF77 correlation receiver
Two seperate receiver channels for signal
conversion and best aquisition and tracking
of the DCF77 signal (AM + PZF).
Synchronization Time:
2-3 minutes after correct DCF77 signal reception
Frequency Outputs:
Accuracy depends on oscillator
(standard: OCXO-SQ)
Pulse Outputs:
Pulse per second (PPS) and pulse per minute (PPM).
TTL level, pulse width: 200 msec
Accuracy of pulsees:
Better than
±
50
µ
sec after synchronization and
20 minutes of operation.
Backup Battery Type:
CR2032 - button cell lithium battery
When main power supply fails, hardware clock runs
free on quartz basis, almanac data is stored in RAM
Life time of lithium battery min. 10 years
Oscillator Options:
OCXO-SQ, OCXO-MQ, OCXO-HQ, OCXO-DHQ
Antenna Connector:
BNC female
Antenna Cable:
shielded Coax cable
Cable Length:
300 m with standard coax cable
LED Indicators
