TVZ3100 satellite school clock

TVZ3100 satellite school clock Tvz3100 Satellite School Clock Tvz3100 Satellite School Clock is the basis of the GPS time code of Qingdao Radio and TV research. Global Positioning System (GPS) is a global network system for the US military's semi-open (open AC code), which consists of 24 semi-synchronous track satellites with star-loaded atomic clocks, and UTC timing accuracy is better than 1 microseconds. ※ Fully automatic work. ※ With software judgment function, intuitive indication signal search, tracking, and losses, etc., and control whether the output signal is opened. ※ There is an output interface of SZ, RS232, RS422, EBU and other formats, and the output of standard hexagonal outputs, which can calibrate various broadcast television equipment and telecommunications, subway, aviation and other industries with standard time interfaces. ※ With a 1PPS signal output, other clock systems can be synchronized. ◇ Initial tracking time: under sufficient signal to noise ratio, not less than 3 minutes ◇ Timing accuracy: 1μs ◇ SZ code output 57-bit, serial BCD flash ◇ EBU code output pin 1, 2, Balance ◇ ◇ RS232 output interface Type: One-way output, 3 foot data, 5 foot; data format: 4800bps, 8-bit data, a stop bit, no parity, send once a second, a total of 9 bytes, in turn is sync word (16 into AA), 00, Year, Month, Japanese, Week, Time, minute, seconds. Its Chinese, month, day, week, hour, minute, seconds is BCD code ◇ RS422 output interface type: one-way output, 3 foot signal, 8 foot negative signal, 1 foot; data format: Output interface with RS232 ◇ Type: Card 2, 3 foot signal, 1 foot, front 5 ring 800Hz, last 1 ring 1600Hz, start a second 1 second 1 second 1 second ◇ ◇ 天天长: standard is 30 meters Time Times Tvz3100 The satellite school clock receives a dedicated satellite receiver GPS and demodulates the AC code to get the time code and second pulse, as a reference standard for the time system, synchronous system clock. The system uses a simple and reliable reception and drive circuit to ensure the output signal delay of the nanosecond; the system output switching uses multi-channel fault-to-error technology and hardware control switching technology to improve the system reliability. This machine is extremely simple, and the receiving antenna is a full-directional hemisphere beam, which should be installed in an outdoor unshoid. The equipment adopts 19 "standard chassis, after installing the rack, turn on the power to see if the system is normal, the system can be automatically coloned. Note: This machine receives antenna and its feed line shall not transfer the extension, otherwise the signal will affect the signal. Quality, resulting in abnormal school. This machine has a standard feeder length of 30 meters. If you need to stay with the supplier.
