These specifications apply when the analyzer is used to make measurements
other
than
error-corrected S-parameter measurements An example would be
the measurement of amplifier gain compression. In such cases, the analyzer’s
output and input behavior-such as source power, receiver accuracy, and
receiver linearity-are important and are covered by Instrument Specifications.
System
Veriffication
Procedure
The System
Verillcation
Procedure tests the network analyzer measurement
system, as
dellned
above, against the System
Specillcations.
If conllrmation
is successful, the measurement system is capable of making S-parameter
measurements to the accuracy specified by the graphs of measurement
uncertainty. An outline of the System Verification Procedure follows:
w
The measurement system is calibrated with the calibration kit to be used
for future measurements The measurement system’s systematic errors are
determined by this procedure.
n The S-parameters of verification-kit test-devices are measured with error
correction applied.
n These measurements are compared to measurement data stored on a unique,
serial-numbered data disk included with the verification
kit.
n
The measurement system passes the System Verification Procedure if the
measurements of the test devices differ from the measurement data on
the data disk by less than specified test limits. The test limits account for
the specified accuracy of the measurement system and the measurement
uncertainties attributed to the stored data for the test devices.
