PZF180PEX
Плата PZF180PEX розроблена як низькопрофільна плата для комп’ютерів з інтерфейсом PCI Express. Задня кришка слота інтегрує роз’єм антени, роз’єм BNC для модульованих часових кодів, 9-контактний роз’єм D_SUB та два світлодіоди стану.
Опис
Плата PZF180PEX розроблена як низькопрофільна плата для комп’ютерів з інтерфейсом PCI Express. Задня кришка слота інтегрує роз’єм антени, роз’єм BNC для модульованих часових кодів, 9-контактний роз’єм D_SUB та два світлодіоди стану. За допомогою цього стандартного кронштейна висоти ви можете використовувати роз’єм D_SUB для сигналів вводу/виводу, таких як RS-232 – PPS та PPM, а також використовувати цей інтерфейс для оновлення прошивки. PZF180PEX постачається з низькопрофільним кронштейном. Ви можете встановити цю частину замість стандартного кронштейна, щоб використовувати PZF180PEX у комп’ютерах з меншим корпусом (наприклад, 1U сервер).
ХАРАКТЕРИСТИКИ
| Receiver Type | Quadrature receiver for optimized evaluation of the DCF signals (amplitude and phase modulation) |
| Status Indicators | The 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. |
| Type of Antenna | DCF77 outdoor antenna AW02 |
| Synchronization | Compared 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 synchronisation. |
| Frequency Outputs | Frequency output 10 MHz, TTL level |
| Pulse Outputs | 3 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 msec |
