And of course there are the ex-Hameg products HMO = Oscilloscopes (7xx, 1xxx, 2xxx, 3xxx) HMP = PSU (2020, 2030, 4030,4040) HMC = Compact... PSU (804x), DMM (8012), Power Analyser (8015) |

--- Quote from: pdenisowski on November 11, 2022, 07:21:58 pm ---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. --- End quote --- The classic R&S instruments had a quite stringent naming scheme, often with an obvious German origin. Today this has become somewhat blurry. But still, all receivers (not just EMC receivers) start with an E, for "Empfänger". For example EB200, ESMD, EK07, EK070, etc. Signal generating instruments start start with an S, and lab RF signal generators still are SMx, for "Mess-Sender", others had a different second letter (e.g. the SNF video level generator, or the SPD pulse generator, SUB audio generator, etc.). The classic R&S power supplies were all NGxx, for "Netzgerät", whereas power and SWR meters were Nxx or Uxx, when considered a voltage indicating instrument. This went as far as that the URV5 was also available as NRV, the only difference being that the NRV would start up in power indicating mode, where the URV5 would start up indicating voltages. Audio analyzers are UPx. This was of course spoiled by the addition of the former Hameg products (power supplies HMPxxx). Frequency domain instruments (in a broad sense) are Fxx, e.g. spectrum analyzers, modulation meters (FAM, FMAB, FAB, etc.), but also counters (FEI, FET, etc.). The classic attenuators were Dxxx, for "Dämpfungsglied". Frequency sweepers were SWxx, the most well known are the classic SWOB series: SWOB, SWOB1, SWOB3, SWOB5. Communication radios are Xnnn, but some old frequency standards also had designations starting with X. I don't know about broadcast transmitters and antennas, but they sometimes also have talking designations. Instruments that were manufactured to the specifications of the German armed forces sometimes had an Y in the designation, for example URY, which is an URV5, or the radio tester CMS42y, which is a version of the CMS54. This is probably due to the fact that the license plates of vehicles of the German Federal Armed Forces begin with a Y. Sometimes there was a little humor in the designations, for example the noise generator SUF and SUF2 ("Rauschgenerator SUF"). Difficult to get that across in English. :) See here for an incomplete list of old R&S gear and datasheets. Edit: The classic R&S scopes are Oxxx, e.g. OBF, OKF, OMF, or special purpose gear like ODFA. |

@rf-messkopf First, thank you very much for that explanation! Quite a bit of history there! --- Quote from: rf-messkopf on November 12, 2022, 09:12:30 pm ---But still, all receivers (not just EMC receivers) start with an E, for "Empfänger". For example EB200, ESMD .... --- End quote --- Except of course for the portable receivers like the PR100 (instead of the TE100) :) I guess products like the ETL (broadcast) and EVSx/EDS (avionics) analyzers could still be considered "receivers" in the larger sense of the word. Any idea why antennas start with H? That's always been a mystery to me. (Hochfrequenz? Hörer? :)) |

Hello, NF-Geräuschspannungsmesser Psophometer UPGS 248.0019.02 Rohde & Schwarz, PTE; München. For people from Munich, Psophometer sounds like a measuring device that measures a person's state of intoxication (noise floor). Because if you drink a lot of alcohol you have a "Rausch" (= intoxication and "rauschen" == noise) and are "bsoffen" (=drunken). Best regards egonotto |
