    Hi,

    Recently, I worked on tuning fork AFM which was controlled by MK3pll, and met some troubles for collecting frequency shift - distance curves. I suppose the procedure should be similer to that of the z spectrum by set parameters in SR DSPcontrol/z and SR DSPcontrol/Graphs. However, in SR DSPcontrol/Graphs tab I can not find any PAC channels. What should I do?

    Many thanks,

    Lifeng

    Hey,

    sorry for the "incomplete" labeling and confusion.

    They are actually mapped automatically in a similar way to

    "ADC0/Mx0", ... "ADC3/Mx3" (select in Graphs) as setup via the mixer!

    I have to admit that I just did very little testing and real work with this so far, please let me know if any problems.

    -Percy

    one more hint: please do not use the "oversampling" (integration) mode for these data channels as of now.
