TROUBLESHOOTING

PERIPHERALS/ INTERFACE

If it fails, contact ANRITSU Customer Service Center.

Step 3. If the problem only occurs in Band 3, replace the Switched

Doubler Module assembly and repeat test.

If it fails, replace Switched filter and repeat test.

If it fails, contact ANRITSU Customer Service Center.

Step 4. If the problem only occurs in Band 2, replace Switched Fil- ter assembly and repeat test.

If it fails, contact ANRITSU Customer Service Center.

NOTE

After replacing a component, perform a Frequency Cali- bration and a RF power/ALC Calibration. Refer to Chap- ter 6, Adjustments.

Check #3

If you have determined that failure occurs in both sweep directions, at

 

all frequencies and Error Code 5110 is recorded in the Service Log, the

 

failed component could be any of the following assemblies:

 

1.

Transfer Switch

 

2.

Switched Doubler Module

 

3.

YIG Oscillator

 

4.

A21A1 YIG Bias PCB

 

5.

A21A2 Source Control PCB

 

Replace the components listed above in sequence. After each replace-

 

ment recalibrate unit (see note above) and retest. If 373XXA still fails,

 

contact your nearest ANRITSU Customer Service Center.
