VITS100 NTSC VITS Inserter Instruction Manual 5–1
Performance Verification
This section contains procedures for verifying that the VITS100 NTSC VITS
Inserter performs according to the characteristics stated in the Specifications
section of this manual.
If the VITS inserter fails to meet a performance requirement, consult the
Adjustment Procedure section and make only those adjustments that affect the
“out of spec” characteristic.
Verify the performance of the VITS inserter at regular intervals to ensure that the
instrument continues to perform within tolerance. The recommended interval for
performance verification is 2000 hours of operation or 12 months, whichever
comes first.

Incoming Inspection Test

Two procedures may be used for incoming inspections. Use the Functional
Check procedure in the Getting Started section to verify instrument function. To
confirm that the instrument meets guaranteed specifications, use the following
Performance Verification procedure.

Verification of Tolerance Values

For Performance Verification, use test equipment with measurement accuracy of
at least four times the tolerance of the specification being tested. If you do not,
the error of the measuring apparatus may invalidate the test results.
