1 Scope

This part of GB/T 17737 applies to coaxial communication cables. It stipulates that the crosstalk test between the coaxial cables used in the communication system law. This method is suitable for cross-talk measurements between coaxial cables of the same type, but it is also applicable to different types of cables (eg different sizes, impedances, Speed ratio, etc.). This method is also suitable for multi-coaxial or integrated cables. Appendix A gives the theoretical basis for cross-talk measurement between coaxial cables.

2 Normative references

The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article Pieces. For undated references, the latest version (including all amendments) applies to this document. IEC 61196-1 Coaxial Communication Cables Part 1.

3 Terms and definitions

The terms and definitions defined by IEC 61196-1 apply to this document.

4 Measurement

4.1 Equipment The measuring device is shown in Figure 1 and consists of the following components. --- Signal generator. The characteristic impedance should be the same as the tested cable. Or with an impedance adapter. When the crosstalk attenuation is large, power should be used The amplifier completes. --- Receiver with Corrected Step Attenuator. For high cross-talk attenuation, use a pre-amplifier if necessary. --- or network analyzer (including generator and receiver). --- Load resistance. The impedance is equal to the nominal impedance of the cable being tested. ......
