Rohde & Schwarz APN04 Audio Frequency Generator

[Mark666]

I bought the APN04 on eBay for a reasonable price but cannot find a PDF file containing the user manual or service manual anywhere online, I have also tried the Rohde and Schwarz website and found nothing whatsoever.  The generator does come with a slide out card but it seems quite vague.

I would much appreciate any help in locating either of the documents if anybody has access to them?

Thank you.

I could only find this https://www.ntecusa.com/docs/APN62_data.pdf which gives the spec of the APN04

That's the only document I could find online. Thank you for looking. 

Might try my luck and email Rohde & Schwarz support.  I have no idea on why there is such a lack of information available.  Seems to be worth the £150 I paid though.  The output is very nice.
