Characteristics of 0.7/2.9 mm coaxial cable pairsdoi:ITU-T G.621
Patched leaky coaxial cable (PLCX) is proposed as an alternative to the conventional leaky cable for wireless links in a complex environment. It is expected to have the capability of adjusting the coupling between the cable and the environment and give smoother electric field coverage. In this ...
RS485 cable in general use ordinary twisted pair can be, in a relatively high demand environment can use shielded layer of coaxial cable. When using the RS485 interface, the transmission line is specific, from the RS485 interface to the maximum cable length and signal transmission load the ...
The role of the day tone: 1. Match the impedance so that the antenna system (day + antenna) is impedance matched for the transmitter, so that the antenna cable in the antenna system has the highest radiation efficiency. 2. Resonant antenna, according to electromagnetic theory, the antenna im...

This report describes the characteristics of an anechoic chamber when imitated equipment under test (EUT) is used. Radiated emission measurements revealed that the use of optically driven EUT enhanced the repeatability of the measurement set compared to coaxial cable driven ones. Measured emission levels...
