  • Re: PFM

    Certainly! There is no special requirement to do PFM (just use contact mode and configure the lockins through generic lockin). I recommend putting the AC bias to the tip and reducing the 'amplitude limit' for the lockin that you are using. I think lockins 2 and 3 are preferred depending on your...

  • Re: Electrical measurements and SAM V

    Tim, #1 is correct. Remember, NEVER put a high voltage input into the SAMV #2 The best way to do this is not to use the SAMV, but is from within the NSV. To do it in the NSV you will need to separate the AC and DC, applying one to the tip and the other to the sample. In general, the performance of PFM...
