This application test aims at the test of non nominal 50 Ω cable, including coaxial, twisted pair, differential high-speed data line, including impedance parameters, s parameters (insertion loss, standing wave, Smith diagram, etc.), and can also draw eye diagram. According to the performance of the cable, such as frequency range, length, difference or not, time-domain […]

The demand for industrial cables / connectors is rising, and the development of domestic connectors has become the focus
According to the relevant statistics of the National Bureau of statistics, from January to October 2020, China’s industrial robots grew by 33.7%. The proportion of industrial robots in industrial production is increasing. The market demand is increasing year by year. In the future, industrial robots will become an irreversible substitute for labor force. As a […]
How do two cables wind together
I have been playing electronics since I was very young. My university degree is in Control Engineering (compulsory subjects include mathematics, electronics, mechanics, and fluid mechanics), so I haven’t received any hands-on training for technicians One day I saw a video on YouTube titled “great idea! How to twist electric wires together. At the beginning […]
Dry goods: common cable consumption calculation formula of five systems
1、 Generic cabling system 01. Horizontal subsystem, cable consumption calculation method Average length of cable = (horizontal distance of farthest information point + horizontal distance of nearest information point) / 2 + 2H (h-floor height) average length of actual cable = average length of cable × 1.1 + (termination tolerance, usually 6) number of cables […]
Industrial robots are constantly updating and iterating, which also stimulates the upgrading of connectors and cables
The latest “world robot report 2020” shows that industrial robots operating in factories all over the world have reached a new high. With the recovery of the industrial robot market, it has also brought new additions to industrial connectors and industrial cables. According to the latest “the new world robotics 2020 industrial robots”, the number […]
Cable management system based on RFID
Due to the hidden operation environment of the cable line, the imperfection of the operation data and the limitation of the channel test equipment, it is very difficult to identify and investigate the parallel cable trench in the same path. When the cable line fails, although the fault point can be found through the equipment […]
Ultra high speed HDMI cable will become the mainstream trend of HDMI cable
First of all, we have to admit that information about HDMI cables can be confusing. Dealers’ promotion of their cable products may vary greatly, and the terminology about this technology may not be very clear. As a result, hot searches for HDMI cables include: “which is the best HDMI cable?” “What is the most suitable […]
The principle of zero line and ground line is explained in detail
Many people’s understanding of the zero line is wrong. What is the principle of the zero line and the ground line? Listen to the teacher carefully. 01 Let’s start with figure 1 There are only three phase lines L1 / L2 / L3 and the neutral line n of the three phase lines. The voltage […]
Analysis of multiple application examples of meta measurement units 4201-smu and 4211-smu
Source measurement unit (SMU) is a kind of instrument which can provide current or voltage and measure current and voltage. SMU is used for I-V characterization of various devices and materials. It is designed to measure very sensitive weak current and provide or scan DC voltage at the same time. However, in test systems with […]
How to prevent fire of power cable in data center
Both the construction contractor and the data center operator have the legal obligation to ensure that the cables in the data center have good fire performance. According to the annual data center survey report released this year by Uptime Institute, a data center standards organization, many data center operators admit that if they invest more […]
