Hi, I am using the Analog Discovery 2 supplies to simulate a battery voltage supply (3.6-4.2V) for a small device with low current consumption (3 - 5 mA). Now I have the scenario where a 5V is applied by the chargee and hence I have a reverse current (around 15-20 mA) to the AD2 supplies pins. I checked the AD2 reference manual and couldn't find something concrete about the capabilities of the analog supply to handle sink current. Does the AD2 supply has an internal mechanism for such a case ? . In case I want to avoid the sink current situation. I was thinking to add a resistor on the AD2 supplies output. Will that be sufficient ?

@attila Thanks. I will try with https://docs.scipy.org/doc/scipy/reference/generated/scipy.signal.butter.html One more question. if I am having the AD 3 / AD Pro instead. Can I simply use the FIIR filter functions from the SDK to set a low pass filter window ? I am referring to these functions in specific: FDwfAnalogInChannelFiirSet FDwfAnalogInChannelWindowSet

Hi I am working on an application where I need to filter some white noise when reading analog data on the AD2 scope channels. In WaveFroms GUI there is the option to add a math (software based filter channel) with low pass filter. As I am using python for the test automation. is there an API function to apply such software based filter at the input I attach an image below for reference. I am looking after to get the filtered output in my test script. Thanks
