NOTE
. Circuit boards that are damaged due to mishandling or containing
modifications not originated by Tektronix are not acceptable for the exchange
program.
When calling to arrange for a circuit board exchange it is essential that you have
some information ready to relay to our technician. The instrument type and serial
number, along with installed options are absolutely essential. In addition, the
Assembly number (A??) and the 9-digit circuit board part number (67?-????-??)
will help ensure that you are getting a direct replacement. Finally, if you know or
are able to provide the software version number it will further ensure that the
circuit board you receive will return instrument performance to what it was
before the failure occurred.
The following paragraphs are intended to assist in ordering the exact circuit
board replacement. Note that this information is important whether you are
ordering a circuit board from the Module Exchange Center or as a new replace-
ment part from Tektronix.
