I am currently sampling the inputs with the internal square wave test signal.
However, I am only getting the square wave in RDATAC mode - not in RDATA (single shot) mode where the response is flat for every channel.
Is this normal behavior? If I change the input multiplexer from "Test signal" to "Normal Input" I can see my ECG signal I am supplying externally (in RDATAC as well as in RDATA mode) so it seems like there is a problem if MUX is set to test signal and device is in RDATA mode.
Any ideas how this could be caused?
