  • Re: PFTUNA I-V curves - why is my Z piezo completely extended

    Hi, thanks for your reply. I didn't state the problem very clearly. The real problem is that the Z piezo jumps into the extended position right after I click Ramp in the workflow panel. It does so regardless of what I set in the ramp settings and before the actual ramping even starts. I tried setting the trigger to Off or setting it to Absolute

  • PFTUNA I-V curves - why is my Z piezo completely extended

    Hi! I am doing some PFTUNA I-V curves on a hard sample using one of those (a bit expensive) DDESP tips. Every time I go into the Ramping screen, my Z piezo position marker goes into a completely extended position. First I didn't pay much notice, because I just thought that the Z marker doesn't provide any reading anymore (the voltage textfield

  • Can you switch your setpoint units back from nm to mV (ie. Classic Setpoint Mode) in NS8.15

    Hello, the setpoint value for every mode is displayed in nanometers in NanoScope 8.15. Could this be switched back to mV as in the older versions? I know this can be done during installation - ie. you can set that you want the Classic Setpoint Mode. But I think someone mentioned to me that it could also be set later in the software, is this possible

  • Re: 50/60 Hz noise

    Hi Solong, I don't remember seeing an oscillation in the Angstrom range and I am not in front of the instrument now. The noise before had an amplitude of about 2nm and it was definitely related to the antivibration table not being inflated. Jakub

  • Re: 50/60 Hz noise

    Ok, if there is someone interested in how this problem was solved: This particular problem happened during an installation of a new Icon and it went away after connecting the antivibration table to the compressed air source. We were waiting for a new compressor to come, but I didn't expect it would be the solution to the problem because of the 50Hz

  • Re: 50/60 Hz noise

    Some more information about the pictures above - I have now grounded both the controllers and the ebox with a grounding wire and the measurements still behave the same. I see hardly any detail, because the 50Hz noise is still visible. Can you advise?

  • 50/60 Hz noise

    I want to discuss here what I believe is a common problem, yet I am often unable to solve it or advise a customer what to do about it - picking up 50/60Hz noise from the power lines. The below image is typical, and I often see this during installations. It's an HOPG sample in Tapping Mode scanned with 1Hz and 2Hz Scan Rate. That way you can actually

  • Icon PT / Nanolithography / Some questions about functions in the C++ libraries

    Hi everyone, today we tried the Nanoman software for scratching into a Polycarbonate sample and we got some nice results. Then we went into writing scripts for Nanolithography and we found that some things we could not do, because we didn't find the right functions and we didn't understand the ones that are in the manual. Is there a macro for
