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 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
embedded on-line help.
IMPORTANT Passing this system verification does not guarantee that the analyzer meets all of its
performance specifications. However, it does show that the network analyzer being verified
measures the same devices with the same results as a factory system which has had all of
its specifications verified and its total measurement uncertainty minimized.
What the System Verification Verifies
The system verification procedure verifies proper operation of the:
• network analyzer
•calibration kit
• test port cables
together as a “system”. It DOES NOT verify that any of these components pass their specifications
independently. The user is responsible for independently calibrating and verifying the proper operation of the
calibration kit and test port cables prior to performing the system verification.
NOTE Additional equipment or accessories used with the above system are not verified by system
verification.
