  1. Thanks for answer, device is AD2 Waveforms 3.21.3 Sure it's running.
  2. I see no measurements in Counter window. Why? And Measurements Tab is inactive.
  3. I guess that corresponding part of example should be corrected in Waveforms Help, because now it looks like ravings of a madman🙂 And on this page also: https://digilent.com/reference/software/waveforms/waveforms-3/reference-manual?redirect=1#code
  4. Maybe it is possible to coorect this in the future versions?
  5. So, I guess it is not possible to control DIOs and Resistor values in non Adapter modes in Custom Amplitude scripts. Am I right?
  6. I did it with Amplitude regulation. And it works as expected. Now, how to realize DIO and Resistor switching in "W1-C1-R-C2-DUT-GND" mode inside Custom Amplitude script?
  7. Definitelly I do not understand something. In script mode Impedance.run() command blocked execution, so it's impossible to do anything till it stops. In Custom script mode StaticIO object does not recognized: Generally, all I want to do is: While Impedance measurements running at every step get DUT Ch2+ voltage in the form of Vrms, Vreal, VImag or something acceptible. If it is < some preset switch to lower Rref(by activating corresponding DIO) and vice versa. Or if events Resistor too small/high are available make the same actions based on them.
  8. StaticIO. does not recognized in custom mode script.
  9. As I understand, Impedance.DIOs.DIOx.value commamd works only in Adapter mode And StaticIO. does not recognized in custom mode script.
  10. Thanks a lot, Attila. That is right and I did not notice. After calibration everything work allmost exactly as with Jaxbird's software. The only thing I could not realize is how to switch automatically reference resistors. They are controlled via DIO1-3. I suspect it could be done via custom mode script, but I could not find how to operate with measurements and controls inside this mode.
  11. Hi, there I made Impedance Analyzer adapter according Jaxbird from eevblog. It works fine with Jaxbird's software. Now I tried to adapt it for WaveForms AI. I made the following adjustments: 1. 1+Res 2+ DUT -1-2 GND configuration. 2. Channel2 Attenuation: 0.0625 (As Opamps give 16x Gain); 3. Reference Resistors: 34, 500, 5000 Ohm. 4. Open/Short calibrations for all Ref Resistors. Now I'm observe strage things: L and C measurements in Meter mode works fine in compare with Jaxbird's software. R measurements are 0.8 of the real values. Could not realize the reason. Maybe somebody will... Also, there is a strange difference in graphic and Meter measurements: in Meter at 2MHz |Z|, Rs, Rp are allmost equal to real resistance value, but in graphic they are much lower.
  12. Hi, there I made Impedance Analyzer adapter according Jaxbird from eevblog. It works fine with Jaxbird's software. Now I tried to adapt it for WaveForms AI. I made the following adjustments: 1. W1 1+Res 2+ DUT -1-2 GND configuration Amplitude: 0.2V . 2. Channel2 Attenuation: 0.0625 (As Opamps give 16x Gain); 3. Reference Resistors: 34, 500, 5000 Ohm. 4.

  13. Thanks for answer. Not sure, that I understand how to measure phase numeric value with FFT, Spectrum or Network Analyzer. The script you provided gives ultimate precision, but acos function is defined in 2 quadrants (0-180 degrees). It is not possible to define DUT nature (inductve/capacity). I'going to use custom script for such mesurements.
  14. IMHO these calculations are redundant sum1 /= c sum2 /= c sum12 /= c @atilla What is the source idea of this phase measuring method? I could not find it.
  15. In my case I observe the following: 1. waveformslive.com works never 2. Any offline version (1.1.2-1.4.10) works fine 3. Downloaded to local folder waveformslive.com works fine except some wrong icons.
