About System Verification and Performance Tests
The performance of the network analyzer is specified in two ways: system specifications,
and instrument specifications. Respectively, the analyzer's conformance to these
specifications is verified in two ways: system verification, and performance tests.
System Specifications
System specifications specify warranted performance of the measurement system when
making error-corrected measurements. The measurement system includes the analyzer,
test cables, and calibration kit.
The analyzer's system specifications are described in the Agilent PNA Series Network
Analyzer Data Sheet and also in the analyzer's on-line help system.
System specifications are included in section titled "Corrected System Performance."
System specifications are expressed in two ways:
• residual errors of the measurement system
• graphs of measurement uncertainty versus reflection and transmission coefficients
System specifications are applicable when the measurement system is used to make
error-corrected measurements.
System specifications are verified in one of the following ways:
• Complete the system verification procedure using a certified verification kit, or
• Complete all of the performance tests and certify (or recertify) the calibration kit that
will be used for future measurements. This alternative verifies both the system
specifications and the instrument specifications for the analyzer.
Instrument Specifications
Instrument specifications specify the network analyzer's uncorrected measurement port
characteristics and its output and input behavior.
The analyzer's instrument specifications are described in the Agilent PNA Series Network
Analyzer Data Sheet and also in the analyzer's on-line help system. The sections that
describe instrument specifications are titled:
• "Uncorrected System Performance"
• "Test Port Output"
• "Test Port Input"
These specifications apply when the analyzer is used to make measurements other than
error-corrected measurements. An example would be the measurement of amplifier gain
compression.
Performance tests are used to confirm that the analyzer meets the instrument
specifications.
