Brad,

HP has a selection of cable scanning/qualification tools which
may interest you. One of them looks very similar to the tool
you mention... The other is called the 28687A Wiretest Instrument
which was designed specifically to provide 10-BASE-T certification
of your wiring. It measures (very accurately/reliably) the following:

- Continuity             (details failures ie: short 1-3, open 3-6)
- Burst Noise            ( Per the 10-BASE-T specs )
- Attenuation            ( < .5dB resolution, 16dB dynamic range )
- Near End Crosstalk     ( < 1dB resolution, 35dB dynamic range)

It has a monitor, print, and continuous measurement capability,
allows you to test from RJ-45 or 50 D-sub connectors, and will test up
to 12 ports at a time. This product is highly recommended for site            
certification and maintenance. Contact your local HP Sales.
