Many thanks

I suspect that unless you have access to NR standards via your work somehow, then this would be a tall order. I can perhaps put some typical examples on the site but there are many and the size is large. However here is a signal output from an SSI module including a tee off to the ATP encoder shown on another sheet and the feed to the AWS via its transformer. Not sure how much use something like this is going to be to you though.....

P.S. PJW what would these NR Standards be if I can source them through work?
