plots in the cable checks (earlier in this chapter) that show the performance of
good cables. It is highly recommended to periodically check test port cables to
determine if they are good.
If the system veriiication is performed with non-HP cables and fails but is then
repeated with HP cables and passes, the non-HP cables are at fault. (It must be
documented in the comments area of the performance verification printout that
non-HP cables were used in the system.) The effects of the non-specified cables
cannot be taken into account in the performance verhkation procedure.

with any calibration kit is dependent on how well the kit standards are dellned.
The measurement specifications for the system assume a measurement
calibration with an HP calibration kit. Measurement calibrations made with
user defined or modified calibration hits are not subject to the performance
specifications, although a procedure shnilar to the standard verification
procedure may be used.
