Was this Welec / Wittig scope at least comparable to Velleman scopes? They had bandwith up to 30MHz or so.
Oh come on, you started that topic by looking at the Wittig/Welec bench scope. You even quoted the specs. Didn't you recognizes these were 100 MHz and 200 MHz oscilloscopes, up to four channels, desktop form factor, color VGA LCD display? So really what is this fixation with a seven year old oscilloscope series?
Wittig tried their hands at a desktop oscilloscope. At the same time Rigol and others were coming out with entry-level desktop oscilloscopes in this form factor. Wittig failed and went bankrupt. The market's most severe punishment for producing something not good enough (should happen to more crap oscilloscope manufacturers). So what more punishment you want to see?
The owners founded a new company (Welec) to sell the surplus they somehow managed to rescue from bankruptcy, or to emerge out of bankruptcy to pay off their debts. They sold the oscilloscopes at a much reduced price. So the market fixed that, too - price affecting supply and demand.
At some point they published the original firmware of that desktop oscilloscope. Years ago I saw some part of it. An incredible steaming pile of shit. One of the worst embedded code I have ever seen (if we don't count Android apps as embedded stuff, and if we exclude Arduino). The best example why hardware guys with no real training in software development should never ever write something more difficult than blinking a LED.
A small group of people had years of fun writing their own firmware for that oscilloscope, the only 200 MHz oscilloscope hardware platform you could get to write code for. Compared to the usual pseudo oscilloscope junk hardware like DSO nano.
So really, what is your point? It is dead Jim. It is no more. It is pining for the fjords.
