Hello! I am looking for an oscilloscope/digitizer that can be controlled from computer via ethernet. I have been using the BitScope 445 http://www.bitscope.com/product/BS445/ (http://www.bitscope.com/product/BS445/) but it's not working anymore and the company is not responding. I know there are quite a few options (Analog Discovery, PicoScope, or CleverScope), but here are some of my main requisites:
- Ethernet interface (as digitizer needs to be far away from computer, and on different ground than computer)
- At least 10 MS/s
- I need to analyze signals from 1 mV to 10 V
- At least two channels with external trigger
- Digitizer software needs to run on Linux and should have Python API
- If it has a rack-mount option, that would be a plus!
Any suggestions you have are greatly appreciated! Thank you!

The combination of features of somewhat high sampling rate, multiple gains and ethernet is uncommon, I believe. So that probably translates into expensive. Do you want to continuously stream samples or is batch wise acquisition like an oscilloscope acceptable? Then a bench scope with ethernet might be the cheapest solution.
Another alternative is a USB DAQ/scope connected to a small single board computer running Linux that connects to ethernet.

I assume needs to be a low budget solution - please take a look at the Digilent offerings:

Ethernet is not built-in, can be done with adding a raspberry pi.

If you need 10 MS/s streaming, then look carefully at the specs. For example the Digilent ADP3250 (https://digilent.com/shop/analog-discovery-pro-3000-series-portable-high-resolution-mixed-signal-oscilloscopes/) is said to sample up to 125MS/s in record mode, but only ~1MS/s in 'Linux mode' (https://digilent.com/reference/test-and-measurement/analog-discovery-pro-3x50/specifications). It wouldn't surprise me if the maximum sample rate via ethernet is also lower.

Thank you. Something below $1k would be nice. I don't need to continuously stream, so what you are suggesting would work. Any scope you would recommend given what I need? Thanks!
