Repeat steps 7 through 9 at least three times to look for modes. Modes
appear when a harmonic of the source fundamental frequency is able to
propagate through the cable or connector. It is helpful to print a plot of the
trace each time to compare several connections. If any mode appears
each time the cable is connected and reconnected, measurement integrity
will be affected.
For a typical response of cable connector repeatability, see
12.
For the Port 2, 3, and 4 Check, connect the cable (with the load attached)
to the respective port and repeat steps 2 through 11.
