Introduction：
CAT5 8158 is produced by Germany Schwarzbeck and authorized by Shenzhen EUTTEST agent sales T8-ISN that is, 8-wire impedance matching network, it can test 4 pairs of wires UTP, the design principle in line with the requirements of the standard CISPR 22 edition 5.2-figure D.3 ( LCL = 65 dB ), CAT5 8158 design schematic diagram The schematic diagram of CAT5 8158 is shown below:
CAT5 8158 Design Schematic
The ISN CAT5 8158 also allows common mode interference voltage measurements to be performed on unprotected twisted-pair UTPs or communication ports with 2, 4, 6, or 8 conductors. The device under test, EuT, or auxiliary equipment, AE, can be connected using an RJ-45 socket. Pin assignments follow EIA/TIA-T568A/B.
CAT5 8158 also complies with the AAN device requirements of CISPR32, details of which can be found by clicking on the link below:
