R&S Cryptic Acronyms
PixieDust:
I’m trying to figure out what the RTC, RTM, RTB acronyms stand for on their oscilloscope names.
And their FPC Spectrum Analyzer.
Any ideas?
Rich@RohdeScopesUSA:
RTO is real-time oscilloscope. For the others, I don't believe there was a "true" name behind them. Meaning they didn't necessarily get their lettering with a specific intent. With that said, we sometimes call them (in the US at least):
RTC = Compact
RTB = Basic
RTM = Mid
RTA = Advanced
RTH = Handheld

TimFox:
In careful usage, an "acronym" is a pronounceable word formed from an abbreviation: e.g., "NASA", "laser", "mosfet".
The etymology of "acronym" is analogous to "synonym", where "onym" comes from the Ancient Greek ὄνυμα (ónuma) for "name".
Non-pronounceable abbreviations are just abbreviations: e.g., "RTC", "RTB", "RTO", "DVM".
pdenisowski:
The first letter generally denotes the type of instrument:
RTx - real time (scopes), but note new MXO series of scopes
Fxx - frequency (spec ans)
Sxx - signal generator
Zxx - network analyzer (Z -> complex impedance)
Exx - EMC receivers
Cxx - communications testers
Nxx - power supplies (but note, NRPxx is RF power sensors). I'm told "N" stands for "Netzgerät"
Numbers sometimes (but not always) indicate maximum frequency (FSW85 - 85 GHz).
"Similar" classes and generations of instruments may have similar names, e.g. the older SMU and FSU versus the newer SMW and FSW. Many handhelds end in "H" - FSH, FPH, ZNH, ZPH, RTH, etc. But beyond that there's no universal naming scheme that I'm aware of.

Note that there are two versions of the FPC, the FPC1000 and the FPC1500. The difference is the FPC1500 has a tracking generator and therefore supports the network analysis option. Both have the same maximum frequency of 3 GHz (not 1500 MHz / GHz ....:))
