I have an ADICUP3029 and an EVAL-AD8302-ARDZ and I peroformed the steps described on this page:https://wiki.analog.com/resources/eval/user-guides/eval-ad8302-ardz#help_and_support.
After an the error's solution descirbed at https://ez.analog.com/analog-microcontrollers/precision-microcontrollers/f/q-a/534706/invalid-shield-error-at-adicup-power-detector-app-for-adicup3029/386536#386536 I was able to connect the board with the software.
Now I finally had the opportunity to measure same data, but unfortunately the board doesn't detect any values.
I used the default calibration and typed in 2.45 GHz and clicked on Measure, but the fields "Gain" and "Phase" only show "NaN".
Can anyone help me to solve this problem, so I can properly measure some data?
Please use the latest software GUI uploaded on this link (https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/EVAL-AD8302-ARDZ.html#eb-relatedsoftware)
Let me know if solve your issue.
thank you, now it shows me some values.
But now I have other problems or questions:
1) I want to measure some data at 2,45 GHz, but then it says, that I have to write a value between 2 and 3, but these are not the frequencies I want to measure. Why it isn't possible to write 2,45GHz or 2.45GHz?
2) When I write 2 GHz it measures the same values while writing 3 GHz or even higher values . It also measures the same values when no cable is connected to the board. The phase delta is round about 54°.
3) Is it possible to implement the feauture to calibrate at 2,4 or 2,5 GHz, because I can only create frequencies between these two values?
Please see my comments below.
1. The software accepts decimal values on the frequency input textbox so you can measure 2.45GHz
2. Please see the figure TPC 18 (VMAG Slope vs Freq) on it's datasheet (https://www.analog.com/media/en/technical-documentation/data-sheets/ad8302.pdf)
based on the figure the slope and intercept in 2GHz up to 2.7GHz are almost the same so the changes in phase
are almost unnoticeable.
3. The slope and intercept at 2.2GHz and higher freqs are almost the same so we limit the calibration point to 2.2GHz
thanks for your answer.
1.) Then I first write 2.45GHz or 2,45GHz and click on Measure, it shows me "NaN". After that I write some integers and it gives me some values and now I can also write decimal values. But it always shows me round about the same values around 54°. Even if I write something like 2450GHz.
Is it possible that one of my components are defect?
I tested the EVAL-AD8302-ARDZ earlier described at https://ez.analog.com/analog-microcontrollers/precision-microcontrollers/f/q-a/534706/invalid-shield-error-at-adicup-power-detector-app-for-adicup3029/386536#386536.
