System Verification

System verification is used to verify system-level error-corrected uncertainty limits for
network analyzer measurements. The verification procedure is automated and is contained
in the firmware of the analyzer.
The system verification section consists of five parts:
1. General Information, on page 2-16
2. Equipment Initialization, on page 2-20
3. Measurement Calibration, on page 2-22
4. Verification Device Measurements, on page 2-25
5. Interpreting the Verification Results, on page 2-31
The device data provided with the verification 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 verification are the sum of the
factory measurement uncertainties for the verification devices and the uncertainties
associated with the system being verified. You can determine your system measurement
uncertainty limits by referring to the analyzer reference guide.
When a network analyzer system passes these tests, it does not guarantee
IMPORTANT
that the analyzer meets all of the performance specifications. However, it does
show that the system being verified measures the same devices with the same
results as a factory system which has had all its specifications verified and its
total measurement uncertainty minimized.
