Functional Test
The purpose of this procedure is to confirm that the oscilloscope functions
properly.
This procedure verifies functions; that is, it verifies that oscilloscope
features operate. It does not verify that they operate within limits.
Therefore, when the instructions that follow call for you to verify that a
signal appears onscreen that is about five divisions in amplitude" or
has a period of about six horizontal divisions," etc., do NOT interpret
the quantities given as limits. Operation within limits is checked in
Performance Tests, which begin on page 611.
DO NOT make changes to the front panel settings that are not called
out in the procedure. If you make changes to these settings other
than those called out in the procedure, you may obtain invalid results.
In this case, just redo the procedure from step 1.
NOTE
If the oscilloscope fails anyof these checks it has failed the perfor
mance verification. To diagnose the causes of a failure, proceed to
the troubleshooting procedures on page 827.
