PNA Series Microwave Network Analyzers Tests and Adjustments
E8361A System Verification
Measurement Traceability
To establish a measurement traceability path to a national standard for a network
analyzer system, the overall system performance is verified through the measurement of
devices that have a traceable path. This is accomplished by measuring the devices in an
Agilent verification kit.
The measurement of the devices in the verification kit has a traceable path because the
factory system that measured the devices is calibrated and verified by measuring
standards that have a traceable path to the National Institute of Standards and
Technology (NIST) (see Figure 3-8). This chain of measurements defines how the
verification process brings traceability to the network analyzer system.
