HP 35680A


 

I came across an HP manual marked 35680A on a well known auction site.? A brief search does not seem to return any hits.
?
Anyone in the group know what it is?? Seems like it might be some sort of low frequency analyzer - 3562A, 35660A, 35665A, 35670A?

Answering my own question - looks like it is the HP Instrument Basic option for the 35660A


 

Well, HP made a 3586A/B/C Selective Level Meter. Does the manual on the auction show a photo of the manual with "35680A" printed on the cover?

The auction does show the manual and it is correctly listed
?
Looks like it is a software option for the 35660A that extends the unit with instrument basic
?
Turns out there is another option, 35681A - 'Analysis pack' - for the 35660A - has anyone got a copy of this one?
