We are trying to make decision on which Cable Test Equipment to buy.

There is a Byte Brothers RWC-100(Real World Certifier)

or a Fluke CIQ-100. One uses Dgital technology, the other Sine wave.

Byte Bros is less expensive, I just need to test cable to a point where we can tell IT co or customer, "This cable is good"' If there is Electrical interference, will these pieces of equipment tell me that and where it is?
