I have the 68369 B manual. Need the A/NV (Army/Navy) manual or calibration procedure.
I saw that there were numerous CP's on GIDEP for either 68369NV or 68369B with various options. I didn't see anything with an A in the model, just NV or B. Not sure if that is any help at all.
I have the manual I think, I am work now and it is at home on an external drive. pm me with your personal email and I will try and get that to you tonight. Also, I may be able to find something later this afternoon for you.
If looking for parts, ANRITSU, I had one I was repairing and on the front panel it was a 68369B, rear panel it was the 68369A/NV (Simply the Navy Configuration), and in trying to order the 40Ghz SDM module they kept telling me the unit was obsolete and NO PARTS Available, turns out they did have the SDM module but according to the serial number I actually had a 68367C....Keep that in mind when trying to find parts for this unit.
Call ANRITSU verify your unit by serial number, may save you some hassle later on b/c from Wiltron to ANRITSU they really had a lot of crossover problems.
Anyway PM me and I will see what I can find for you.
