Modular measurement and control instruments prevail, where is the outlet for domestic brands? Tengfang Zhongke TFC
With the increasing popularity of MI (modular measurement and control instrument) (including PXI PXIe PCI PCIe, etc.), as the initiator of PXI concept, NI heat gradually increases. As can be seen from Baidu index heat, NI heat index has steadily increased from 1600 since January 2021, and by May 2022, the heat index has exceeded 2900. In the niche market, has begun to bear fruit.
The modular measurement and control instrument is to integrate the original test instrument in the form of modules, and realize the parameter adjustment and data analysis through software. The advantage of modular measurement and control instruments is that they are highly integrated. Not only can the equipment be highly integrated and reduce the area occupied, but also the data can be integrated and analyzed through software, making the operation more convenient. Then its disadvantage is also very obvious, that is, the precision control is not accurate. At present, it is also the point where the big brothers in the industry are breaking through.
The author believes that there are three reasons why NI can occupy the main advantage in this track,
One: put forward the concept of PXI, is the forerunner of this industry, there are a large number of cases accumulated experience;
Second: based on the Lebview open source platform, the establishment of a forum, accumulated a large number of users;
Third: the development of comprehensive product types, such as bus series, the current domestic brand has not been able to do.
In addition, the author also found a particularly interesting phenomenon. NI customers are also very loyal to accessory cables. Even if the price is relatively high, the delivery period is relatively long, and some are not very convenient to use, but many customers are still willing to accept it. In my opinion, on the one hand, it stems from the brand trust in NI. The board and cable are the same brand, and the quality should be more guaranteed and more durable. On the other hand, it stems from the fundamental lack of confidence in some domestic cables. Some low-price competition on the network makes the product quality unstable, such as twisted pair, tinning, softness and insulation.
However, the author recently found a treasure domestic brand, which is not inferior to NI original in quality and even superior to the original factory in electrical performance. This company is Tengfang Zhongke located in Changsha. Take NI's 68PIN cable as an example. This domestic brand not only provides VHDCI668-to -68 ordinary twisted-pair shielded cables, but also provides EPM flat-shaped multifunctional cables. In order to improve the stress of the flat cable, they also upgraded the softness of the cable to make it more convenient for users. The following figure shows the cable softness test.
At the same time, the insertion loss, time delay and impedance of the product were tested, and some parameter values were slightly higher than the original ones.
In addition, according to the actual use of the customer, they also introduced the loose line form, which is really too understanding of engineers and very humanized, because in actual use, most test engineers do not use the original connector at all, which leads to the purchase of the line has to be cut and retested before the line sequence can be connected, which is very troublesome.
With this scattered line, the efficiency of engineers can be obviously improved. Moreover, the brand did not increase the price of the product because of this design, but reduced the price of the product according to the actual cost. What can't be done with such affordable and humanized cables. The most important thing is that the self-produced cables are also in stock. There is no need to detour abroad to buy one.
The author believes that Tengfang Zhongke's product model is worth learning from other brands, learning to deeply understand customer needs and make up for market vacancies, instead of blindly lowering prices in the same category. To make the product useful to customers, let customers recognize the value of the product, this is the brand should pursue the goal, but also the best way out for the brand.
