It is a BS310, but the range has been updated since: http://bitscope.com/ They claim "very cost effective". You can judge for yourself here: http://my.bitscope.com/store/?p=list&a=list&i=cat+0 This is the current version of the one I have, but a couple of hundred dollars cheaper than 6 years ago: http://www.bitscope.com/product/BS325/ Near the bottom of that page you see their 100:1 1kv probes. Get a couple like that, whatever you buy. It's 40 MS/s, like the Hantek, I see: http://www.bitscope.com/product/BS325/?p=specs This link shows how you could leave a Bitscope hooked up to a customer machine, go home, and later monitor it over the internet. They have a demo unit running in Sydney that you can hook up to, if you download the software on the page: http://www.bitscope.com/software/?p=demo Disclaimer: I haven't tried that. > It is not that I am sticking with the cheapest possible solution, the > intended budget was up to 300 eur.

That was precisely my thinking when I bought the BS310. The price is long forgotten, and I've had the money's worth of use out of it. Using a laptop as host would have a secondary benefit if a battery supply were also made up for the Bitscope - total isolation! OK, that'd only rarely be of much benefit, but good for where you have to stand on a non-metal chair, wearing rubber boots, to test a bit of equipment. If you need more than 8 logic analyser channels, then ISTR that you can hook up two of them, and cross-trigger, making a 16 channel analyser. I'd send them an email if you wanted to go down that path, e.g. for the wall printer. Do you have access to the CMOS or TTL logic levels, rather than just the print head drive voltages?
