AM700 Audio Measurement Set Service Manual
4–1
Performance Verification
These functional checks are used to validate that the AM700 Audio Measure-
ment Set is operating normally. They do not check each of the performance
requirement given in the Specification section of this manual.
As part of these procedures you will run the diagnostics procedures to ensure
those portions of the instrument tested by the diagnostics routines are performing
correctly.
Test Equipment Required
The test equipment needed to perform the verification procedures is listed in
Table 4–1. Use the test equipment shown or an equivalent to do the verification.
If the example test equipment is not available, check the Minimum Specification
column to determine if you can use another piece of test equipment. If you use
other test equipment, the controls and connectors for that equipment may be
different from those called out for the example test equipment. Refer to the
appropriate operator’s manuals for operation of the test equipment.
