Procedures
Use the following procedures to check the Model 3162A and the 3162B
against the specifications. A complete set of specifications is listed in
Appendix A. The following paragraphs show how to set up the instrument
for the test, what the specifications for the tested function are, and what
acceptable limits for the test are. If the instrument fails to perform within
the specified limits, the instrument must be calibrated or tested to find the
source of the problem.
In the following, 3162B tests refer to both 3162A and 3162B
models. If you own the Model 3162A, simply ignore tests that
pertain to the B channel operation.
