The system show me in error log: "z sensor does not work please check the controller or head hardware", but the engage happen normally. Is this a consequence of problem with deflection vs Z scan plot?

Hi The Piezoresponse mode works fine with AC voltage applied to the tip and sample grounded, but not in inverse way (AC voltage applied to sample and tip grounded) any idea why?. Other issue is get deflection sensitivity, I was working this parameter through force-plot in multimode following instruction in user manual, but in Dimension I have two problems

thank for your help now I am working pfm in Dimension with nanoscope IV, and I trying with multimode too with the same sample holder and voltage applied to piezo cap and there I can to measure voltage. But is true the electronic in multimode and basic extender isn´t able to work optimally in PFM, my question is why some papers report multimode

Hi Peter This lock-in amplifiers can be used for piezoresponse force microscopy ? Thanks.
-
Have the Nanoscope-IV controller lockins amplifier integrated?

Hi Ian I have tried to perform PFM measurements on ferrolectrics materials for phase and amplitude, but the results are not good due to high noise in amplitude signal, wrong signal phase from the lock-in (maybe for delay in electronics basic extender+lockin). So I was checking the probe holder and the pin 1 and pin 2 don´t have any connection

Hi, I am going to start measures in Electric force microscopy with Dimension 5000 and Nanoscope IV system, but the application note was written for nanoscope IIIa and basic extender. So What I need for EFM with my hardware configuration?.

Regards, I'm working in PFM technique with Multimode SPM, Nanoscope IIIa, SAM III and Nanoscope Basic extender and I need technical information about How work the feedback loop and electronic in photodectector to separate the PFM signal from the topographical information. Thank you.
