5.3.4.6 DC Resistance Unbalance Testing
Using the MS-TestPro DC Resistance and Looper modules, you can test the DC resistance of CATx
cables, and check their ability to provide a sufficient level of PoH (Power over HDBaseT) powering.
The DC Resistance module is inserted into the lower slot in the MS-TestPro main unit, while the CATx
cable is connected to the DC Resistance module at one end, and to the Looper module at the other
end, as depicted in the figure below:
