Title: System and method for measuring characteristics of communication cable
Inventor: ROJIYAA AREN BIJIYOOKU
IPC: H04B3/46
Filed: 1990-04-03
Abstract: PURPOSE: To judge whether or not a communication cable supports a digital communication by sending pulses to the communication cable, detecting at least one pulse at one end of the cable and analyzing a reflected pulse. CONSTITUTION: A CPU 14 and a time area reflection meter TDR 16 are used for transmitting incident pulses through a communication cable 12. In response to that, a waveform containing pulses reflected by the cable 12 is detected by the TDR 16. This waveform is digitized as plural time samples and a primary, a secondary, and a tertiary derivatives are calculated. When only one positive significant pulse is found, the length and attenuation quantity of the cable 12 are calculated and then the S/N showing whether or not the cable 12 is suitable for a digital communication is calculated. On the other hand when >=2 positive significant pulses or one negative significant pulse are found, it is judged that the digital communication can not be made.
