Interpreting the Verification Results
The purpose of the N5251A system verification process is to demonstrate that the system is
making reasonable measurements. There are no hard specifications on the N5251A 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.
