Cable Connector Repeatability; System Verification - Agilent Technologies HP 8719D Service Manual

7.
Place a marker on the largest deflection that goes above and below the
reference line and is within the specified frequency range. See F'igure 2-5 for
example plots of this measurement.
In this S11 measurement, the displayed trace results from energy being
propagated down the cable and reflected back from the short. Therefore, the
measured deflection value must be divided in half to reach the correct value.
If the cable does not meets the speciilcations in the cable manual, it should
be either repaired or replaced.
