APPX A-1
Appendix A
PCB CONNECTOR INFORMATION
This appendix contains all of the connector mnemonics used throughout the HP 5890 Series II. It is
intended to help the technician isolate problems to a specific component or components. The HP 5890
Series II may be found in many different configurations, with varying component options. This compli-
cates the process of providing detailed troubleshooting procedures for even general problems. But, by
using the general troubleshooting techniques presented in Section 1, along with the pinouts given here,
successful results should be achieved.
