content: Picoscope 3203D MSO vs R&S HMO1002The 1002 costs about 120 euros more but it's memory is 1Mpts compared to 64Mpts of the 3203D, datasheet specs seem to be pretty much the same, so is the 120e just for the display and buttons, or is there more to it?ThanksOscar

content: Why do you consider only HMO1002 for a stand alone scope? If budget is an issue there are less expensive ones.(I use a HMO1002 and it works very good for me, wouldn't replace it with any headless oscilloscope)

content: The 3000 series PicoScopes are excellent tools. They have some unique features and for most applications, I would prefer it over a conventional entry level scope.Pros:- Complete package. Goodies like advanced triggering, segmented memory, mask limit test and serial decoding are included right from the beginning at no extra charge.- Serial decoding supports vastly more protocols than any other scope in this segment.- Scalable screen Size. You can run the scope within a tiny window as well as full-screen on a HD monitor and the scope will always use the full resolution available.- High trigger rate up to 130000 wfrms/s.- Unrivaled FFT analysis up to 2MPts, including automatic measurements of signal properties in the frequency domain.- The use of logic channels doesn’t reduce the number of analog channels.- Tons of acquisition memory available.- The smaller models are USB powered.Cons:- No intensity grading by default. There is a special persistence mode, which slows the waveform update rate and is generally less convenient than having everything combined in one operating mode.- Maximum input voltage only some +/-20V, which translates to +/-200V with a 10x probe.- No extra “probe head” for the logic channels and the supplied cables are only some 25cm long. So the scope itself acts as a probe head and has to be placed next to the D.U.T.

content: I wouldn't have said it better.get a pico if you need to do a lot of logging and serial data analyzing.for example, we got one of the 2000 series because we needed SENT protocol decoding.Last time i checked the cheapest low tier scope that decoded SENT was a keysight DSO/MSO X3000. with a dedicated software option.Same situation is for all other protocols beside UART,I2C,SPI and CAN
