CharacteristicsType of receiverQuadrature receiver for optimized evaluation of the DCF signals (amplitude and phase modulation)Type of antennaDCF77 outdoor antenna AW02Status infoThe Field-LED is switched on if a DCF-signal with at least minimum field strength needed for the correlation receiption is detected at the input of the receiver. Whenever the reception of the pseudorandom PZF signal is not possible but the AM signal is available, the \'Field\'-LED starts to blink once per second with a pulse duration of 100 or 200ms, corresponding to the demodulated DCF pulses.SynchronizationCompared to the former PZF computer clock the PZF180PEX not just provides the capability to evaluate the common amplitude modulated AM signal it is also able to decode the high-precision pseudorandom phase noise. If the PZF signal is disturbed an cannot be received, the PZF180PEX automatically switches over to decode the AM signal, if available, and ensures synchronization.Frequency outputsFrequency output 10 MHz, TTL levelPulse outputs3 Programmable TTL outputs, per default configured as:
Channel 0: Pulse per second (TTL, RS232 level), pulse duration: 200 msec
Channel 1: Pulse per minute (TTL), pulse duration: 200 msec
Channel 2: DCF77 compatible pulses (TTL level), pulse width: 100/200 msecAccuracy of pulse outputsBetter than +/- 50μsec after synchronization and 20 minutes of operation.InterfaceSingle serial RS-232 interfaceData format of interfacesBaudrate: 300, 600, 1200, 2400, 4800, 9600, 19200 Baud
