Agilent Technologies 4263B LCR - Replacing the A2 CPU Board Assembly; Replaceable Assembly List

Replacing the
A2 CPU
Board Assembly
The
A2
CPU
Board
Assembly has
a ROM
for the
rmware and
an EEPROM
for the
adjustment
data
and
user
data.
Both ROM
and EEPROM
are mounted
in sockets
for easy
replacement. If
the
A2
assembly
is
replaced, the
ROM and
EEPROM may
be transferred
from the
defective
assembly
to
the
new
assembly as
long as
the ROM
and EEPROM
are not
defective.
The
ROM
transfer
reduces
parts
cost for
the repair
, and
the EEPROM
transfer
saves
time
from
readjusting
the
4263B
.
For
this purpose
,the
A2 assembly
can
only
be
ordered
without
the
ROM.
When
the
A2
assembly
is replaced,
make sure
that the
jumpers and
switches
on
the
A2
assembly
are
in
the
default position
as shown
in Appendix
B.
