Hi
I am FAE in Japanese distributor.
Our customer evaluate ADUCM355 with M355_ECSns_CycloVoltammetry sample soft(Keil uVision).
He uses 2 kind of void AD5940RampStructInit(void) function and run from initialization.
Please see attached waveform.


REO(green) and SE0(yellow) are both discontinuous.
Could you advice how to avoid the discontinuous?

Best regards
