DIAGNOSTICS MENUS

APPENDIX A

NOTE

The service log must always be printed out or saved to disk and sent to the factory along with a failed assembly. Due to the importance of the information provided by the service log to ANRITSU factory Service Engineers, the ex- change prices are only valid if the service log data (disk or printout) is submitted to the factory with the failed assem- bly.

This menu is available to service and non-service personnel. However, the service log should be cleared by service personnel only.

Installed Options The INSTALLED OPTIONS menu lists installed option numbers and descriptions.

This menu is available to service and non-service personnel.

Peripheral Tests The PERIPHERAL TESTS menu (DG3) tests the printer and GPIB ports, internal VGA monitor, front panel operation, and the external IBM compatible keyboard (if keyboard is connected). These tests will require some interaction and external devices such as the Printer Test Connector (ANRITSU PN: B39553), a GPIB cable, and an external IBM compatible keyboard as appropriate for the specific test.

This menu is available to service and non-service personnel.

Troubleshooting The TROUBLESHOOTING menu (DG4) and its sub-menus provide a host of pre-defined internal system modes and sub-system monitors that provide information useful in evaluating proper system operation. Most of these modes do not require any interaction or external test fix- tures. (An exception is the FIRST IF BANDPASS selection which re- quires a thru line to be connected between the test ports.)

Menu DG4A and its sub-menus provide low level access to internal system hardware. These menus allow the user to control system latches, switches, and DACs. They also allow selection of key system states such as set-on or search for lock. Many internal analog voltages may be monitored via the 373XXA built-in DVM monitor network.
