  1. Hello attila Now everything works as it should. Many thanks for a super quick fix.
  2. Hello, When I try to use closed compensation (10 Ohm Range) in Meter mode in the Impedance Analyzer module, the program automatically closes and exits to widnows. In contrast, compensation works well in Analyzer mode. This error has been around since the last few beta versions. I would also like to add a function that automatically remembers the compensation coefficients until the next compensation (Short and Open). PS. WaveForms version 3.11.33 on Win10 x64pro
  3. Hi Ferda I am currently at the stage of designing an external adapter PCB similar to this presented video (I read the whole post about it on eevblog). This adapter should at least solve some of the problems you're talking about (eg stronger output based on LT1210 or BUF634). PS. Do you have a link to the program that the author of the attached video use?
  4. Hi attila. Thanks for voltage scale fix in dark Ni theme. I also have some technical questions about Impedance Analyzer. 1. What is the difference between compensation in menu A and menu B. 2. Is compensation in menu A also applicable in CC or CV mode 3. Is the phase also corrected during compensation (short or open) 4. How many samples are collected for one period of the measured waveform (sampling ratio) 5. Which algorithm is used to calculate the impedance and phase. If you can please share meta code Thank you very much for your suppor
  5. Hi tauquir_iqbal This should help. https://en.wikipedia.org/wiki/Four-terminal_sensing https://www.allaboutcircuits.com/textbook/direct-current/chpt-8/kelvin-resistance-measurement/
  6. Hi attila Thank you very much for the nice implementation of the new features I asked for: Min/Max function is also very cool (protects against burning the precious chip). Beta 3.10.5 Added: - Power Supplies for AD2: tracking, slider, min/max - Impedance Analyze: DC mode compensation PS. In the tab of the power supply when I using the NI Dark theme, the voltage scale (near sliders) is not visable.
  7. Hi @ attila At the beginning I would like to thank you very much for your quick response. It is also very nice to watch how the software develops and also how many functions are implemented at the request of customers and how good the support is. -The CC/CV mode was added to WF beta 3.10.3 I will be testing the new version 3.10.4 next week. I am now outside the home "laboratory" -You can find the schematic of IA Adapter here: https://reference.digilentinc.com/reference/add-ons/impedance-analyzer/start Yes I saw the scheme but my goal is not only to automate the switc
  8. Hi @attila The WaveForms software is getting better and better from version to version. In the future, I plan to build a more advanced version of the adapter, i.e. with a better analog frontend: input with PGA maybe on AD8251, AC coupling for inductor measurment with dc bias ( 10A max) , a stronger generator output (lower impedance, perhaps on LT1210) and a better transimpedance amplifier (LT1210 + AD8066). This adapter should extend the measuring ranges (1 Ohm or smaller), for very small inductor and very large capacitances (small ESR). I also wonder how it can be controlled from W
  9. WOW ! WaveFoms Beta 3.10.2 is out, and has almost all the features I asked for (and much more) 😀 Impedance Analyzer: - voltage, current and custom plots - edit Meter list - Resistance mode for Meter, Frequency DC option - step mode in Time view Netowrk Analyzer: - step mode in Time and FFT views - amplitude table and custom function Thank you very, very much attila. WaveForms is a great software and Digilent is a very good company that cares about the customer
  10. Hi attila 1. I think that is a very good idea. For example, an list from which the user selects any parameter to display 2. Indeed, adding a new DC operation mode (Ohmometer tab) is a good solution. Hardware solution for DC resistance measurment may look like that Thank you for such fast response Best regards, Fonak
  11. Hello I'm new to the forum but I have a few suggestions to improve the impedance analyzer: Please add: 1. Simultaneous display of parameters for the serial and parallel model in meter mode 2. Measurement of the parameter (meter and analyzer mode): - Rp (equivalent parallel resistance) - Vrms (actual voltage on the DUT) - Irms (actual current flowing through the DUT) - Complex values for voltage on DUT (Vreal, V imagined) - Complex values for current on DUT (Ireal, I imagined) - Rdc measurement of DC resistance (in my opinion it should not be difficult to imple
