Performance verification
This section describes the procedures to verify the performance of your
instrument. Performance verification procedures confirm that a product meets or
exceeds the performance requirements for the published specifications
documented in the
Specifications chapter of this manual. The performance
verification procedures certify the accuracy of an instrument and provide a
traceability path to national standards.
NOTE. The performance verification procedure is not a calibration procedure.
The performance verification procedure only verifies that your instrument meets
key specifications. For your instrument to be calibrated, it must be returned to a
Tektronix service facility.
Prerequisites
The tests in this section make up an extensive, valid confirmation of performance
and functionality when the following requirements are met:
■ The linear equalizer and other test equipment used in these procedures must
have been operating for a warm-up period of at least 20 minutes after starting
the LE application and power applied to the linear equalizer.
■ The linear equalizer must be operating at a stable ambient temperature.
■ No error messages are displayed in the user interface.
Functional checks
This section describes procedures to verify that the instrument is functional, but
