With the development of the mode of time service and the diversification of time service, the current mode of time service is not limited to NTP network, PTP, serial port, pulse and so on. IRIG-B code time information is also a way of timing. In practical applications, due to the large number of received IRIG-B codes, the time code distributor should be used as the interface box to carry out multiple output IRIG-B code information.

The time code distributor can allocate the standard IRIG-B code input signal to the output of multi-channel IRIG-B code signals. IRIG-B code is a serial transmission method commonly used in time transmission. It has the characteristics of simple physical connection, long transmission distance, standardized interface and international common characteristics. It is an indispensable time signal in the fields of telecommunications, power, military and so on, and there are more time service devices in these fields. Therefore, SYN1401 time scale allocator is often used as the interface box, and the IRIG-B code will be used all the time. The inter signal is allocated to multiple channels, so that more devices can receive time signals and achieve higher precision time signal and time unification.


The SYN1401 time scale distributor can divide the time information and transmit it to each device. In practice, it can solve the problem of time synchronization in various industries and scenes. For example, in some large-scale performing activities, it is very important to synchronize the time between devices, such as clock, audio, video, lighting and broadcasting. If you can gather the status of these devices to view and manage, you will save a lot of unnecessary manpower and material resources. The interface box SYN1401 type time divider can allocate time information to audio, light, video, clock and other devices, ensuring the time synchronization of each device, so as to achieve the coordination of the performance time.

The SYN1401 time scale distributor can also solve the problem of time synchronization when applied to the aerospace field. With the increase of aircraft avionics, the number of test parameters has increased from dozens of original parameters to hundreds of thousands of parameters. The airborne test data acquisition unit and record unit have also increased, and more and more devices are needed to integrate the time information. Therefore, SYN1401 type time scale distributor is needed for time signal shunting.

The SYN1401 time scale distributor receives the time signal of the time server and outputs it to the corresponding slot or card on the recorder and collector. The recorder automatically decodes the input time information on its own display, and the time information of the collector is decoded and displayed by checking the software. The time signal after the shunting of the SYN1401 type time divider is consistent with the time signal of the SYN4505A type clock synchronization system, so that the device can smoothly give time and punctuality to the collector and recorder in the airborne test.
