APPENDIX A

DIAGNOSTICS MENUS

CAUTION

Always exit the troubleshooting mode via the DG4 menu selection FINISHED, RECOVER FROM TROUBLE- SHOOTING to insure proper system state recovery from your troubleshooting activities.

These menus are for service personnel only.

H/W Calibrations The H/W CALIBRATIONS menus perform various internal automated hardware calibrations, including ALC and Frequency calibrations. The following equipment is required for these tests:

￿HP 437B Power Meter (or Gigatronics 8541/42 Power Meter)

￿ANRITSU ML24XXA with Version 2.02 or later, with ANRITSU Power Sensors MA2474A and (TCD) for 65 GHz units.

￿EIP 20 GHz series counter w/ GPIB (Option -08)

You need only connect the power meter or counter appropriate for the 373XXA model, invoke the calibration desired, and wait until com- plete. The ALC and Frequency calibrations take 5 to 10 minutes each. See Chapter 6, Adjustments, for further information.

The disk operations allow storage and retrieval of internal hardware calibration data to and from floppy disk. This feature will be useful when replacing the A9 Processor PCB since it contains the Battery Backed RAM where the internal hardware calibration data resides.

Automated field calibrations for the LO1 and LO2 assemblies are not presently implemented. Should these assemblies fail or require any adjustment, they must be replaced under the exchange assembly pro- gram (refer to Chapter 1).

These menus are for service personnel only.
