Use AD5940 for cyclic voltammetry detection

Category: Software
Product Number: AD5940
Software Version: Keil MDK


When I used AD5940 for cyclic voltammetry detection(Using Nucleo-F411 as MCU), the data curve obtained was not ideal and transitioned around 0.25V.

The parameter settings in the program are shown in the figure below:

I want to know the following questions:

1.Why does the above phenomenon occur during cyclic voltammetry detection?

2.How should I debug and optimize to get better test data?

3.What do A and B in the parameters set by the code represent and what is the specific meaning of these two parameters?
