Choosing the right test limit when setting up for a test is arguably the single most important step. While changing the Cable Type tells the tester what type of cable to you are going to test (see this article for more information on the Cable Type setting), changing the test limit tells the tester how you are going to test it. There are several factors to consider when choosing a test limit:
What adapters are being used?
What level of performance are the connectors and cable rated for?
Does your customer have a specific testing requirement? If you have a contract, read it carefully.
Is the purpose of the test to get the warranty from the cable manufacturer? If so, check which test limit the manufacturer requires for the model of cable that you are testing.
The two primary types of adapters used with the DSX CableAnalyzer are Permanent Link adapters and Channel adapters. There are also Patch Cord Adapters and COAX adapters available, as well as a few other specialty adapters, all of which can be found in the “accessories” list on the DSX Product Page.
