If you have a really good cabling system, you may see the message "*All test data above limit caps" on your test report, as shown below:

The cabling standards require us to record the final PS ANEXT as Information Only when it exceeds 67 dB. So when the final PS ANEXT exceeds 67 dB, you will see "* All test data above limit caps".

Or you may see for PS AACR-F:

The cabling standards require us to record the final PS AACR-F as Information Only when it exceeds either 67 dB or 72.5-15log(f/100). So when the final PS AACR-F exceeds either 67 dB or 72.5-15log(f/100) you will see "* All test data above limit caps". You may see the PS AACR-F pass through the limit on the graph, yet the overall result is a PASS. The limit caps can cause this to happen. For more detail on this, please click here..
