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

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
BoardAssembly of
the HP
54501A
.
The functions tested are
the six
separate
memories and five other
functions of the
board . To invoke

,
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 usedby factory service personnel
when troubleshooting
the System Board
Assembly
.

Failure of any of these selftests in-
dicate a
failure on the System BoardAssembly
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 .
