Hi to all:

I have a Avecom, PSA37-D spectrum analyzer, but it not work well. Need the
schematic diagram, electrical diagram or service manual for recalibrate or 
reparate it.

I write to factory but they say: 

"Nothing in electronic form—everything I have would have to be scanned to be 
sent, and it is way too much material to consider doing this. Sorry."

If some people have some information , please send me a copy. If is in printed 
format I will pay the cost.

Thanks
