Verifcation Kit - Agilent Technologies HP 8719D Service Manual

System Verifhtion
This system veri&ation consists of four separate procedures:
1. Equipment Initialization
2. Measurement Calibration
3. Verilkation Device Measurement
Interpreting the VeriIIcation Results
4.
The procedures consist of equipment initialization, calibrating the analyzer with
a calibration kit, measuring a set of characterized devices, and comparing the
resultant measured data to the data and uncertainty hits supplied with the
verification kit.
The device data provided with the veri&ation kit has a traceable path to a
national standard. The difference between the supplied traceable data and the
measured data must fall within the total uncertainty limits at all frequencies for
the system verification to pass
The total measurement uncertainty limits for the system verilication are the
sum of the factory measurement uncertainties for the verification devices
and the uncertainties associated with the system being vetied. Ybu can
determine what your system measurement uncertainty limits are by referring to
'Determining System Measurement Uncertainties" located in Appendix A, at the
end of this manual.
When an HP 871OD/20D/22D system passes this test, it does not ensure that
the system meets all of the performance specifications However, it does show
that the system being verilied measures the same devices with the same results
as a factory system which has had all its specifications verified and its total
measurement uncertainty has been mhimized to the smallest extent possible.
A verillcation kit is used in the following procedure, The kit consists of two
attenuators, a 2511 mismatch airline, a 5OQ airline, a data disk containing the
System Vdicatiin and
