Technical specifications
RECEIVER: Two seperate receiver channels for signal conversion and best
aquisition and tracking of the DCF77 signal.
Reception via external ferrite antenna AW02.
CONTROL OF
RECEPTION:
The DCF-signal is checked for minimum field strength by micro-
processor. The result is indicated by LED.
In addition, the value of the digitized field strength is displayed in
menu 'FIELD'.
BATTERY-
BACKUP:
In case of power failure an internal realtime clock runs crystal-
precise. Important parameters are stored in the system-RAM.
Life time of lithium battery: 10 years minimum
Option: backup capacitor for about 150 hours
DISPLAY: Eight-digit alphanumeric display shows important time and status
information. Digit-height 5mm.
INTERFACES: Three independent RS232 ports
BAUD RATES: 600, 1200, 2400, 4800, 9600 or 19200 Baud
FRAMING: 7N2, 7E1, 7E2, 8N1, 8N2, 8E1, 7O2 or 8O1
PULSE
OUTPUTS:
Active-high and active-low pulses per minute and per second,
TTL-level, pulse duration: 200ms
Active-high pulses per 15 minutes, TTL, pulse duration: 200ms
ACCURACY
OF PULSES:
Time delay of two systems PZF511 with a maximum distance of
50km: typ. 20µs, max. 50µs
Time shifting of successive pulses: max. 1.5µs
PROPAGATION-
TIME
COMPENSATION:The signal delay is compensated if the distance of the receiver to
the transmitter is given.
