Attention: Mr. Henricus Koeman


Dear Henri,

This is to acknowledge receipt by Bell Laboratories of a pair of Fluke DSP 4000 Field Testers which were sent to us for evaluation. I would also like to thank you for your cooperation in working towards a complete standard for Category 6 cabling. The ability to accurately test Category 6 cabling in the field is extremely important to our customers. The extended frequency and new test parameters such as Equal Level Far End Crosstalk (ELFEXT), Return Loss and Delay Skew are important additions to the cabling standards.

Our Bell Labs’ researchers, who developed the SYSTIMAX® SCS GigaSPEED® Cabling System, evaluated your test set for several key parameters defined in the draft standard. Those results were compared to those of our laboratory network analyzer in combination with precision baluns and fixtures. When testing GigaSPEED channels using the Lucent Technologies GigaSPEED menu setting and GigaSPEED Test Adapter, we found a high degree of correlation in the tests performed and concluded that your Fluke Corporation DSP 4000 Field Testers are suitable to characterize the performance of installed GigaSPEED channels.

We compliment you and your technical staff on the significant improvement in tester accuracy that you have been able to achieve and look forward to continued cooperation. Please provide us with the opportunity to evaluate future upgrades to your software/firmware as they become available.


Best regards,


Robert J. Paradine Jr., RCDD
