All vendors claim you can get their units measuring within a couple of minutes of starting to install the control software and, in this respect, all three units comply. Because my PC has just one parallel port, as do many PCs, and having it occupied by the cable to the DSO module, means you have to swap cables from the Pico and TiePie units each time you want a printout. Using a second serial port, which many PCs have as standard, makes Cell's module more convenient for printouts. It's Intuitive, of Course There can't be many PC user-interfaces that vendors don't claim to need only intuitive operation. If a user interface is really intuitive, then I expect to be able to operate basic functions without much figuring out, and certainly without a users' manual.
Nobody has time today, especially using a scope, for consulting handbooks or help pages.
Several days, weeks, or months may pass until you need the DSO again and you don't want to relearn basic operation. At this stage, I found some divergence between the three models under examination. Both Cell's ScopeManager software and Pico's PicoScope software are straightforward to use and the important controls for input channels and timebase settings are obvious for anyone familiar with scopes. I found the TiePie module's operation somewhat cryptic, although at no time did I have real problems displaying waveforms or making measurements. Only the Cell unit helps you to do this.
