Section 3. Performance Tests; Introduction; Equipment Required; Test Record - HP 54501A Service Manual

3-1 . INTRODUCTION
This section provides procedures to test the
electrical performance of the HP 54501A ac-
cording to the specifications in table 1-1 of this
manual . Although the HP 54501A internal
selftests provide a high confidence level of sys-
tem functions, the performance test
procedures may be performed upon incoming
inspection of the HP 54501A and periodically
to ensure and maintain peak performance .
3-2. EQUIPMENT REQUIRED
Equipment required for the performance tests
in this section is listed in the Recommended
Test Equipment table in Section 1 . Any
equipment that satisfies the critical specifica-
tion listed in the table may be substituted for
the recommended model .
3-3 . TEST RECORD
The results of the performance tests may be
tabulated on the Test Record provided at the
end of this section . The Test Record lists the
performance tests and provides an area to
mark test results . The results recorded in the
table at incoming inspection may be used for
later comparisons of the tests during periodic
maintenance, troubleshooting, and after
repairs or adjustments .
3-4. SELFTEST VERIFICATION
To verify a high confidence level of system
operation without the test equipment neces-
sary for the performance tests in this section,
the HP 54501A selftests may be performed .
The internal tests verify functions on the
System Board Assembly of the HP 54501A .
The functions tested are the six separate
memories and five other functions of the
board. To invoke the HP 54501A SELFTEST

MENU , press front-panel UTIL key and then
select selftest menu softkey . A message will
be displayed with the instruction to remove all
inputs to the HP 54501A . Selecting test all
softkey will invoke a loop which runs all the
selftests in succession . During execution of
the selftests, the following messages will be
displayed as each selftest is completed :
PASSED System RAM,
PASSED Non-Volatile RAM
PASSED Display RAM
PASSED Protected Non-Volatile RAM
PASSED System ROM
PASSED Acquisition RAM
PASSED Logic Trigger
PASSED Timebase
PASSED D/A Converter
PASSED HP-113
PASSED A/D Converter
When one of the self tests have failed, FAILED
will be displayed rather than PASSED, and a
16-bit diagnostic code will be displayed . This
code is used by factory service personnel
when troubleshooting the System Board
Assembly . Failure of any of these selftests in-
dicate a failure on the System Board Assembly
which must be returned to the factory for ser-
vice. For more information on service, refer to
section 6 of this manual .
NOTE
The loop test in the SELFTEST MENU is
a troubleshooting aid for factory service
only .
