I have a question about using OpenChoice and TekVISA with my TDS220. I'm aware that the device is no longer supported, but have switched to TekVISA v 4.0.4.2, which appears to work with the 220. I just want to know what version of OpenChoice I would need alongside this version of TekVISA and where to get it. If this information isn't available, what other software could I use to transfer a copy of my screen as a bitmap, to then use with Excel?
