I would like to bring the following to Darcy's attention:
1) The major difference between a DSP-100 and DSP-2000 are a much
brighter display and the automated fault diagnostic.
2) The DSP-100 and DSP-2000 both measure the same things: attenuation,
NEXT, length, propagation delay, delay skew AND return loss.
3) The Single Test mode of the DSP-100 provides access to all
diagnostic capabilities. Only the DSP-2000 does invoke the right
diagnostic test directly and you therefore do not have to think
about how to troubleshoot a link. We are still challenging our
competition to accuracy measure the Channel configuration (which
carries your data - the DSP-100 is still the only cable tester
independently certified to meet all requirements of TIA TSB-67
for the channel configuration; everybody is certified to meet
the same requirements only for the test (basic link) configuration)
and to accurately determine the location of a NEXT fault.
(Opens and shorts are no problem for anybody, we all use the TDR
function.) Please note that when you exchange the test cord
for your own user patch cord, the NEXT will change up to 2 dB for
a nominally compliant link due to the mating of a different plug
and jack of your horizontal link .....
4) A software upgrade for the DSP-100 includes all the other things
like Power Sum NEXT, prorated attenuation for zoned cabling, etc.
So you really do not lose out on very basic measurement capability.
This software update is available real inexpensive: No charge!
We nevertheless note your disappointment and maybe our marketing
folks have to reconsider. (I am just an engineer very familiar
with the capabilities of both instruments). I am sure that in the
future there will be new product offerings. At this time I feel very
confident about the performance of both the DSP-100 and DSP-2000
relative to what is offered by the competition. Do not hesitate to
learn what is offered. I hope you will not get confused by
irrelevant and misleading claims ... Of course we can be accused
of doing the same thing ...
I can just say: we have UL certification, which we believe is most
rigid in meeting requirements, and we have statements of all the
major cabling suppliers that indicate approval of our cablemeters
to certify the performance of their networks.
I hope you do not feel treated unfairly after this explanation.
