Interpreting the Verification Results
The purpose
of the N5250C system verification process is to demonstrate that the system is
making reasonable measurements. There are no hard specifications on the N5250C system, so
there are no pass/fail limits from the system verification measurements. the results allow the
user to compare the actual measured data to the factory measured data for each verification
device.
The example traces on the previous pages show typical differences between measured and
factory data. Ignore phase differences for S
11
and S
22
when comparing measured data to
factory data.
