I have an R&S FSAS 1.8GHz spectrum analyser with tracking gen. The tracking gen amplitude is very low about -30dBm.
I need a service manual for the masjien, even if it just for the tracking generator.
unfortunately there are only few documents for the R&S FSAS available, but if you write an e-mail to our colleagues from Customer Support (customersupport@rohde-schwarz.com) giving the reference number RS#489927 they will try to help you.
all the best,
Gerti from the Rohde & Schwarz Social Media Team
