I also use the pctestinstruments. One of its strong points is that it plays well with virtualbox - I run it in a W7 guest on my centos desktop. The buffer depth is usually a bit limiting though, and triggering is also somewhat basic.
Another option that I haven't seen mentioned: use the built-in logic analyzers that the fpga tool chains come with - you'd have to wire up an fpga and sample the signals you need, but all the complexity of triggering, buffering and displaying would be done by the tool chain. -- Sytse > On 14 Mar 2023, at 08:50, Martin Bishop via cctalk <cctalk@classiccmp.org> > wrote: > > Paul > > Some options for consideration, not all meeting your specific requirement > > https://www.pctestinstruments.com/index.asp 34b wide, sync (200 MS/s) or > async (500 MS/s) operation, fights with Win11 - driver upgrade required > Had one for ~15 years, now has a few dead channels, merits consideration > > https://telonic.co.uk/product/siglent-sds1104x-e-4ch-100mhz-1gsa-s-super-phosphor-oscilloscope/ > https://telonic.co.uk/product/siglent-sla1016-mixed-signal-option/ > https://telonic.co.uk/product/siglent-sds1000x-e-16la/ > 4 ch CRO + 16 ch digits : OK as a basic scope and logic capture device > My standard CRO these past few years, rarely used above 4 + 8 configuration > "100 MHz" means this is not a signal characterisation scope - definitely > challenged above 50 MHz > Note Based on bench experience I dont rate the equivalent Rigol boxes, e.g. > DS1074, the GUI is challenged and the HCI processor very sluggish.
