Introduction:

CAT3 8158 is produced by Germany Schwarzbeck and authorized by Shenzhen EUTTEST agent sales of T8-ISN that is, 8-wire impedance matching network, with theCAT5 8158 The difference is that CAT3 is suitable for CAT3 network cables. CAT38158 conforms to ( LCL = 55 dB ) standard CISPR 22 edition 5.2 - Figure D.3 for 4-pair wire UTP, the design schematic is shown below:

The ISN CAT3 8158 allows to perform common mode interference voltage measurements on unprotected twisted pair (UTP) or communication ports with 2, 4, 6 or 8 conductors according to CISPR 22:2005 or EN 55022:2006. It has connectors to accommodate a wide range of network cables, as shown in the figure below:

CAT3 8158 connectors can be adapted to a wide range of network cables.

The connectors can be adapted to a wide range of network cables

In addition to measuring the interference voltage, the CAT3-8158 allows measurement of the immunity in progress. CISPR 24 or EN 55024 up to 80 MHz. For testing IEC 61000-4-6 an additional 50 Ω-150 Ω impedance conversion option (EAB8 50-150) is required, which can be easily mounted on the CAT3 8158 and is available as an option.

The CAT3 8158 also meets the AAN device requirements for CISPR32, details of which can be found by clicking on the link below:
