N5230A System Verification
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.
