I've had *so* many requests for information about NQA The Prophet, a
product that I mentioned in one of my responses to "RE: strange
behavior involving repeaters" that I thought it would save a bit of
time by posting to the list some information about this product.  I've
seen a demo of the product (on our live network) but have not had
hands-on experience with it and have no incentive from any company or
individual to promote it.

The literature claims that the product can tell you about the
following (this is a direct quote from the documentation):

- Network Bias - bias of the coax cable due to the summation of 
  transceiver bias currents
- Jitter - random distortion of packet timing caused by network defects
- DC Signal Component - the average DC value of a transmitted packet
- AC Signal component - the AC range of a transmitted packet
- Fall Time - a parameter related to e.m. noise radiation of the coax
- Bit rate - the frequency of the transmitted packet.

The dealer that I went through to get product info was:

Innovative Computer Products
6284 Rucker Road
Suite E
Indianapolis, IN  46220
(317)257-3278
(800)228-LINK
(317)259-6698

however I'm sure there must be others somewhere.  Its expensive, starting
at around 30K for a basic unit.
