SOURCE/TEST SET/RECEIVER

TROUBLESHOOTING

Step 3. Determine whether the failure occurs during forward mea- surements (S11, S21) and/or reverse measurements (S22, S12):

If the problem occurs in both directions at all frequencies, the fault could be in the Receiver Module, Signal Source Module, or Test Set Module.

If the problem occurs in both directions at only certain frequencies, the fault could be in the Signal Source Module.

If the problem occurs in only one direction, the fault could be in the

TEST SET MODULE.

Step 4. Run the 37XXX Test Software (2300-178) program to verify operation of the Buffer Amplifier, A1 LO1 PCB, A2 LO2 PCB, and Source control PCB.

Use the information obtained in steps 1 – 4 above to determine whether the failure occurs in the Source Module, Test Module or Re- ceiver Module. Replace the suspected failed assembly, and perform any required adjustment(s). Then retest. If the 373XXA still fails, contact ANRITSU Customer Service Center for further assistance.

NOTE

To obtain technical service support from your nearest ANRITSU Customer Service Center, refer to Paragraph 1-8, Service Support Information.

Check #2 If you have determined that the failure occurs in both sweep direc- tions, only at certain frequencies, and that Error Code 5110 is re- corded in the Service Log, use the following procedures to determine which assembly may have failed:

Step 1. Set the 373XXA Start and Stop frequencies for the follow- ing bands:

Band

 

Start

Stop

 

 

 

1

22.5*/40 MHz

2.0 GHz

 

 

 

 

2

2.0

GHz

Upper band-edge frequency

 

 

 

for model. (20 GHz for

 

 

 

37369A)

 

 

 

 

3

20.0

GHz

40.0 GHz (for Model 37369A

 

 

 

only)

 

 

 

 

Models 37311A and 37317A

Step 2. If the problem occurs in Band 1, replace the Down Con- verter assembly and repeat test.
