Hi @attila
thank you for the fast answer.
How can i get this SDK manual?
I downloaded the current version of waveforms (v3.18.1_64bit). The WaveForms SDK Reference Manual, which i got after installing waveforms v3.18.1_64bit, has no entry for this command. On page 33 is only the command FDwfAnalogInChannelImpdeanceGet(...).
