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

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.
