GPJ Yes, it's an option easily accessed. under the MATH menu, where you can toggle between XY and YT(normal 2-channel display) . When I received mine, I checked the signal generator with the oscilloscope and it appears that the bandwidth is around 20MHz. I found the same thing with a 100MHz oscilloscope, so the bandwidth seems to be that of the signal generator. I have yet to test the oscilloscope.

GPJ I have been using the watch for some weeks now and it works well. The battery lasts 10-14 days, however I was wondering how it measured the ECG. There appear to be two electrode pads on the back, but the leds come on during the measurement. I noticed that it seemed to work even if the pads were not in contact with my wrist and that it also worked if I wasn't wearing the watch at all. I then compared three of the "recorded" traces over several weeks and found them to be identical. It is evident that it is not measuring ECG at all, which is a risk for anyone expecting warnings of arrhythmia.
