CHECKING YOUR
INSTRUMENT'S PERFORMANCE
A.l
INTRODUCTION
This Performance Check Procedure verifies the Performance
Requirements of the
222
DSO as listed in the Section
8.
These checks
may be used as an acceptance test or as a preliminary trouble-
shooting aid to help determine the need for repair or readjustment.
You do not have to remove the instrument cabinet to do these checks.
All checks can be made with operator accessible controls and
connectors.
A.2
TEST EQUIPMENT REQUIRED
Table A-1 lists all the test equipment required to do the Performance
Check Procedure. Test equipment specifications described are the
minimum necessary to provide accurate results. For test equipment
operation information, refer to the appropriate test equipment instruc-
tion manual.
When you use equipment other than that recommended, you may
have to make some changes to the test setups. If the exact example
equipment in Table
A-1 is not available, use the Minimum Specifi-
cation column to determine if any other available test equipment
might be adequate to do the check.
