The synchronous time server has the characteristics of high precision, good stability, no accumulation error and no influence on regional climate, so it is widely used in aerospace, power, finance, education, communication and other areas with high precision. This article briefly describes several factors that affect the price of time server.

The synchronization time server's protocol packet is NTP or SNTP. The need to popularize SNTP is only a subset of the NTP protocol. Of course, the technology will be much simpler, the R & D cost will be less, and the price will be cheaper. Many businesses in the market will not deceive consumers in order to occupy the market, SNTP will pretend to be a NTP agreement, and users will be unable to give time when the time is synchronized. It is suggested that manufacturers with their own R & D strength and focus on time and frequency industries should be selected, and the price should not be low.

The synchronization time server outputs the format and the number of signals. Commonly used synchronous time servers transmit satellite signals, 1 or 2 NTP can meet the needs of ordinary enterprises and institutions, such as increasing input and output of B codes, such as AC and DC, PTP and other signal formats. Serial ports and 1PPS add hundreds of dollars each. NTP is about 2 thousand yuan, B code is about 500 yuan, and PTP is about 3 thousand yuan. In general, the richer the format of input and output, the more the number of routes. The price of time server will naturally be much more expensive. When purchasing, we will recommend the most suitable rather than the most expensive user.

Different time keeping modules have different prices. The synchronization time server punctuality accuracy is the accuracy of time server relying on the internal clock source when it does not receive the satellite signal. The general internal clock source can choose the temperature compensation crystal oscillator, the constant temperature crystal oscillator, the lock crystal oscillator and the rubidium atomic oscillator. The temperature compensation crystal oscillator is slightly worse, the 2 day error is less than or equal to 1s, the constant temperature crystal oscillator has a 1-10ms error of one day, the worst 10ms, and the rubidium clock 1 years is also 5ms. Of course, the temperature compensation is the cheapest, the price of rubidium clock is the highest, and the constant temperature crystal oscillator is centered. The more frequently used rubidium clock is the inconvenient installation of the antenna, and the long time use of rubidium clock.

Standard products or non-standard products, these two price differences are the biggest. Synchronous time server, if the user's needs are matched with products, it is the best, cheap and fast delivery. However, if the function is complex and needs not to be customized, the delivery time of the synchronous time server will be about 2-4 weeks, and the price will be much higher than that of the standard product. Because once customized, the R & D department, the production department, the testing department and the quality inspection department almost have to go through each department again, and eventually they can deliver the goods, and the time and manpower cost are relatively high.

In addition to the above factors, the synchronization time server price is closely related to several items, such as whether to add lightning arrester, redundant dual power supply, GPS and Beidou antenna feeder length, and whether to go to the scene for technical guidance.
