Performance Tests

The procedures in this chapter test the electrical performance of the signal generator.
These tests do not require access to the interior of the instrument.
This chapter contains the following information:
• Required Test Equipment List
A list of all the equipment required to perform these manual performance tests. For a
comprehensive list of all test equipment required to perform these tests plus the
manual adjustments, and the automated adjustments and performance tests, see
Chapter 5, "Service."
• Performance Tests
The manual and automated performance tests required to verify the signal generator to
its specifications. Most of these performance tests are performed manually, however,
there is a single automated performance test.
The Power Level Accuracy performance test is the automated test. If this test is run,
the RF level Accuracy performance test, one of the manual tests, does not need to be
performed. The description for this automated performance test is located after the
descriptions for the manual performance tests. Refer to "Service Support Software" in
Chapter 7 "Adjustments" for information on using the service support software that
runs this performance test.
• Test Records
A test record for each model of the 8648 is located at the end of this chapter. These test
records are used to record the measurements for the manual performance tests. Keep
these copies as masters and use a photocopy for each calibration.
See Chapter 4, "Specifications," for the specifications for each 8648 model.
