TROUBLESHOOTING

 

Step 4.

Retry boot-up. If fail, replace the Floppy Disk Drive.

Screen Display

If the 373XXA system appears to have no screen display, perform the

Problems

preliminary check below and then perform checks 1 - 3, as appropriate:

 

Preliminary Check - Press the 373XXA Power key off and then on sev-

 

eral times. Each time power is reapplied, pause and wait for the

 

373XXA software system to boot-up. During boot-up, observe the top

 

left hand portion of the CRT display.

 

 

NOTE

 

 

An alternative method to reset and re-boot the software

 

 

system is to press the red button on the A9 Main Processor

 

 

PCB. Observe the messages displayed on the screen dur-

 

 

ing the boot-up process. Verify that the following messages

 

 

are present :

 

 

￿ Initializing front panel knob (A14/A20)....

 

 

￿ Initializing GPIB (A13/A18)....

 

 

￿ Initializing external keyboard (A13)....

 

 

￿ Initializing external trigger (A13/A5)....

Check 1:

If during boot-up the 373XXA does not attempt to display any mes-

 

sages at all, proceed as follows:

 

Step 1.

Replace the A15 Graphics Processor PCB.

 

Step 2.

Retry boot-up. If fail, replace the Internal VGA Monitor.

 

Step 3.

Retry boot-up. If fail, replace the A9, Main Processor PCB.

 

Step 4.

Retry boot-up. If fail, contact ANRITSU Customer Service

 

 

Center.

Check 2:

If the system halts before it completes all five digital sections, process

 

as follows:

 

Step 1.

Replace the PCB indicated on the last displayed message.

 

 

Example: If the system halt at the “Initializing front panel

 

 

knob (A14/A20)....,” replace the A14 and A20 PCBs.

 

Step 2.

Retry to boot the system. If it still fails, contact ANRITSU

 

 

Customer Service.

5-6SYSTEM HAS ERROR

If the 373XXA detects a problem during normal operation, an error mes-

CODE

sage consisting of an error code followed by a brief error message will be

 

displayed on the screen. The error code will also be written to the service

 

log along with some of the operating data gathered from the system at

 

the time of failure.
