8-472.
MATE SIGNATURE ANALYSIS SUMMARY
8-473. There are three active components in the MATE Block that are not fully diagnosed by signature
analysis. They are the microprocessor, U2, the RAM, U8, and the EPROM, U9. Should signature analysis fail to
detect a problem on a known bad board, these three components should be replaced, one at a time.
8-474. When signature analysis troubleshooting is completed, switch off power to the Counter, return U704 to
its socket, and plug the W1 cable back into the main board J15 connector.
This completes the troubleshooting procedures for the MATE Block.
8-475. FIELD INSTALLATION OF OPTION 010
8.476. Only Option 010 Oven Oscillator is available for field installation.
8-477. To obtain the necessary parts for installation of Option 010, order by part number as listed in Section
VI. Contact the nearest HP sales office listed at the end of the manual if there are any questions about parts or-
dering or option installation.
8-478. In the following installation procedure, it is assumed that an instrument is currently without the option
being installed.
CAUTION
Static electricity can result in permanent degradation or catastrophic
failure of the instrument or assemblies removed from the instrument.
All work performed on instruments, or on assemblies, must be at
static-safe work stations providing proper grounding for the operator.
NOTE
Whenever using a wrench on the front panel, be careful not to scratch the
paint by turning the wrench while it is is against the panel.
