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 onĆscreen 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 4Ć11.
DO NOT make changes to the frontĆpanel 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 any of these checks it has failed the perforĆ
mance verification. To diagnose the causes of a failure, proceed to
the troubleshooting procedures on page 6Ć33.
