By referring to the evaluation board manual, I learned that THE ADUCM355 can test two electrochemical channels, each of which has three/four electrodes.Can I test the output and transfer curves of the FET with a single channel? Thank you!
Do you mean Ids VS Gate voltage of a FET?
ADuCM355 can take 2 Electrochemical channels, reading one at a time.
the ADC in ADuCM355 takes a differential input with:
positive input which is analog voltage or current(ex:AIN0) ,
negative input which is analog voltage or current(ex:AIN1) .
Ex: One of them may be Ids, the other be Vds.
or, Ids and Gate Voltage can be sampled alternatively and transfer curve be found.
