Descripción de Demo of Wittig / Welec W2022a 200Mhz Digital Oscilloscope:
End-user demo of a Wittig / Welec 200Mhz digital storage oscilloscope purchased off eBay for $600-$700 during March 2008. There's a total lack of third-party info available for these units, so this is a step towards fixing that. The ten cent summary is, great sampling value for the money (no other 200Mhz scope retails for below double that price), but the firmware is a bit slow at times, and is somewhat buggy in places. In particular, when the capture is stopped, it is not always possible to zoom or scroll the display. Doh! The makers are releasing periodic firmware updates, so hopefully the bugs will go away someday. I now have a review page about the scope at http://rtr.ca/welec_w2022a/
