Decided it was time to replace my tired TDS220 and thanks to this link, I took the plunge as well.
Unit arrived yesterday, returned it today after calling Amazon. Front panel (not screen) was stained with what looked like hard water spots that had dried. First probe tested was dead on both 1x and 10x. Third probe test was intermittent with slight manipulation of the cable exit on the probe body.
The box had not been resealed, had one layer of Siglent tape on it. So, this was either a factory refurb or beats me, just really bad luck.
First use and I discovered the serial decoder is limited to only 115.2kb but it appears to be a very useable, inexpensive scope.
Has anyone else experienced the quality issues I had? Still debating if I should reorder one and take a second chance.
