I have an ancient Link Instruments digital scope pod that interfaces via IEEE-1284 parallel port. I think I can get the software for it running, but it is pretty limited, requires Windows and a parallel port. Can anybody recommend a decent and inexpensive 2-channel scope pod that works with Linux? An Ethernet interface would also be nice for galvanic isolation, but I don't see any that have that.
I looked up Pico Technologies, and their scopes and software look real good! Are there any others out there?
Thanks,
Jon

Depending on your bandwidth needs something from Bitscope might suit: http://bitscope.com/ (http://bitscope.com/) but I’d get a cheap Rigol or Siglent scope with an Ethernet interface and remote control it with Sigrok or LabView

Picoscope have lots of models, and offer Linux software and drivers.

Pico are definitely good, and their software works on Linux. But other than their lowest end devices (dataloggers really rather than oscilloscopes) they're not inexpensive.
However pretty much everybody else (except the Tek one) are REALLY poor and may be supported on windows only - and with crummy software.
I think there was one that Mike H said wasn't awful but I don't remember what it was. Maybe Owon ?
Update : this one https://www.youtube.com/watch?v=vO712DvGAKA (https://www.youtube.com/watch?v=vO712DvGAKA)
Not sure what the support is for that - not in sigrok, at least.

What are your bandwidth requirements? the owon vds 1022i has software that works on linux made by florentbr. It's 25MHz 100Msps 2 channels. large thread about it here: https://www.eevblog.com/forum/testgear/owon-vds1022i-quick-teardown-(versus-the-hantek-6022be)/ (https://www.eevblog.com/forum/testgear/owon-vds1022i-quick-teardown-(versus-the-hantek-6022be)/)

I recently got a DreamSourceLab U2P20, it's not the cheapest, but I've been pretty happy with it, the included probes are kinda meh, and the BNC connecters wiggle just a little, but it has 200 Msps and a 50 MHz bandwidth and the Linux software has been pretty pain free and solid with the big asterisk that you do have to compile it, but whether that's an issue is dependent on how comfortable your are with compiling. I'd recommend it if you have to stick with USB. They also have the U3P100 that's 100 MHz and 1 Gsps, but at $300 US I'd probably try to look for a used bench scope.
There's also the Hantek USB scopes that are significantly cheaper, but only work through the open source openhantek software on Linux, so you'd be at the mercy of the developer for continued support.
Hope this helps out.
