Scientific Atlanta 4671 Baseband Analyzer Manual

[kiheiman]

A vendor shipped me a 4671 box by mistake (I was supposed to get a 4661).  Does anyone know of a manual for the 4671?  I am trying to get it to work with my existing 4661 to measure NPR when the units are back to back.  It seems that the NPR is not very good when I set the 4661 to 0 dbm out (about -67 dbm).  However, if I set the 4661 to -10 dbm output and the input to the 4671 to -10, then I can get a NPR of about 77 - which seems to be in the ballpark of what I should be reading.  Not sure if my control settings are correct.  I have a manual for the 4661, but it only briefly mentions the 4671.

Do you need a user/operating manual or the service manual?

If you need the service manual there are plenty of sites to search from. Just check out this thread:

Maybe it will help you.

A service manual or user manual would be nice.  I need to figure out how to use the unit with my 4661 noise generator.

I have done quite a few searches and could not find anything.  I did find a manual for the 4661 companion unit and was able to purchase the manual on eBay.  The Scientific Atlanta user manuals are very good and include a full set of schematics.

Alright, I'll try to find it then.

The latest I found was this one here: http://www.etestmanuals.com/Search.aspx?Search=Scientific%20Atlanta%09%09IF/Baseband%20Analyzer%20Instruction%20Manual%20w/%20Schematics.%204671
It is the one on the top ...and unfortunately it costs 100 bucks and they only have one in stock

Thanks.  I contacted the vendor and they cannot find the manual.

I'm sorry to hear that. Have you asked the seller if he has the manual or if he knows anyone that has at least a copy of the manual?
