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 AC freq (use lockin 2 for high freq). The Dimension

Hi Don, I'm really sorry to hear that. Scott will be missed by all of us. Thanks for the information, --Bede

Hi Deepak, This probably merits a call to service, but you might want to try the following first: check the cables between the controller and the multimode as well as the head cable. Power down controller, unplug them, check for bent pins or crimped cables, replug them. Power up and 'Reset' controller Hope that helps! --Bede

In 2016 the MATLAB toolbox was significantly updated to support new data formats. Additionally, it has been moved to a separate installer to make it easier to get set up and productive. I do not recommend trying to use the older versions (supplied with Nanoscope Analysis versions prior to 1.80) any longer. A free copy of the latest version of the MATLAB

Earlier this year the Matlab toolbox was significantly updated to support new data formats. Additionally, it has been moved to a separate installer to make it easier to get set up and productive. Please let me know if you would like an upgrade! --Bede

This question would be better addressed directly to the service group, but it sounds like your vacuum pump in the stage controller box is failing. Service can be contacted at AFM dot Support at bruker dot com. Good luck! --Bede

Hi Sjoerd, It is generally assumed that the spring constant is constant with temperature. That is probably not precisely true (modulus and dimensions of materials like Si change a bit with temperature), but the variation should be small compared to the uncertainty in the measurement. If you want to investigate this further, you could try thermal tuning

How are you doing the export? By right clicking on the plot or by right clicking on the files in the browser? --Bede

The calibration should not be affected by the functionalization unless it coats the cantilever with a relatively thick layer. You could check by looking at the resonant frequency before and after. Generally it is easier to calibrate in the medium that you will use to do your experiments (and deflection sensitivity must be calibrated that way), but you

You can get a copy of the deflection signal from the front panel on the NSV, but it is updated at a 100KHz (imaging) or 40kHz (ramping). Also the front panel signal is clipped at +/-10V. If you need access to the raw signal, the method depends on the microscopy type. What type of system do you have? --Bede
