Fluke 6060B - Module Replacement Procedures

CAUTION
If any of these
assemblies needs calibration
or If any non-field
replaceable part
needs repair,
order
a replacement
using
the Module
Exchange
Program.
To order
a
replacement
module, use the
part number
for
the assembly shown
in the List of
Parts
and specify a Module
Exchange
part.
Table
4D-1 shows
a list of replaceable
assemblies. To order any
new assembly,
refer
to Section
5 for the part number,
(New
assemblies
are ordered by referring
to the same part
number). Note that
two
versions of
the Synthesizer assembly
are available, one
with the Low-Rate
FM option and one
without the option.
The following
paragraphs
describe
the available exchange
modules,
how
to install
them, and how
to
adjust the
Generator,
if necessary,
after installation.

The Power
Supply PCA comes
complete
with the 5V
regulator, A

its socket, and a
set
of insulated
washers for all of the
chassis-mounted
regulators.
No adjustment
is required after
installation
of
the
new PCA, but
the power supply
voltages should be
verified,
using the last
step of the Power
Supply Adjustment
procedure
in this section.
4D-5.
Synthesizer
PCA, A2A1
Under the Module Exchange
Program there are
two versions of the
A2A1 Synthesizer
assembly available. One
has
the Low-Rate FM
option installed on
the
Synthesizer PCA
and the other
does
not. Therefore, when
ordering a replacement
Synthesizer module
be
sure to specify whether or not the
Generator being repaired
has the Low-Rate FM
option.
Also,
before replacing the
Synthesizer
PCA it
is
important
to
note what other
options
are
in the Generator
and carry out the
following
instructions
pertaining
to the option
complement
of the Generator, If
the Low-Rate
FM
option
is present,
verify that
S
I
on the
PCB option is set
for
Low-Rate
operation.
(See
Section
6.)
4D-2
After the
new
Synthesizer PCA has
been installed,
perform
the FM
CAL, VCO CLAMP,
and 10-MHZ
adjustments
as described
in the
Synthesizer
Adjustment
Procedure
in
Section 4C of this manual.
Perform any other
adjustments
related
to the options.
