    I was looking for an affortable, compact and stand-alone V-I Curve Tracer. Something you don’t have to connect to a scope to view V-I curves. I happened to see uCore UCE-CT220L and I soon realized it was what I was looking for. Compact, with a Display and with an affordable price. I ordered it and I have to say I’m happy with it. I use it to troubleshoot electronic boards by comparision and it works as expected. It lacks pulse generator but I knew it from the beginning and I don’t really use it anyway (I had a VI tracer with pulse generator at office before). This VI tracer has two channels (useful to compare boards), a function to save images of the VI curves, connects to PCs with USB ports, easy to update when uCore releases updates (that just happened, this show that product is supported). By now I’m satisfied with it. Adding a Very Low Range would make it perfect to detect very low differences in very low power logic boards where very small differences in data/address bus between board (difficult to detect) are signs of something wrond with the signal. Hope it will be added in near future. I’m not in any way affiliated to uCore alectronics. I just appreciated very much its work and wanted to let others (and uCore itself) know it. There’s some good work going on here!
