Hi, I am looking for any information to help maintain and service the RDL/Aeroflex NTS-1000A or the NTS-1000B phase noise analyzers. There was never a factory service manual produced for either instrument. The operating manual has only a cursory and very much simplified block diagram. Somewhere, someone must have engineering drawings, copies of schematics, personal notes, or something related to the detailed internal design of these units. I own two of the NTS-1000B units, both in very good condition, that I'd like to keep in service for some time. I am very much hoping to find someone who has worked at RDL in Conshohocken, PA. I am willing to pay for any assistance, or for copies of relevant and useful information. Aeroflex in Wichita has now ceased all support for the RDL product line.
I also would like information on any of the companion DCR series low noise down-converters, especially the DCR-14000A.
Thank you.
