Can you provide short description how to calculate real values of resistor and/or capacitor(inductance) from the values of Real and Imaginary registers?
The ADuCM350 DFT engine outputs the results as a complex number. The magnitude and phase of the impedance at the excitation frequency can be calculated by using the following formulas:
Phase = atan(I/R)
R- Real component of the DFT Result.
I- Imaginary component of the DFT Result.
In 2-wires example we are using ratiometric calculations to measure the unknown impedance.Hence, you have use the following the procedure for getting actual magnitude and phase.
Magnitude Zknown =( Magnitude of Zunknown measured/Magnitude of RCAL measured)*RCAL value .
Phase = Zunknown Measured Phase- Zrcal Measured Phase.
I am attaching an excel sheet which can perform this function.
I can not find attached excel ?
I can see the excel sheet.You have to go to the full discussion thread from the inbox to view I guess. I am attaching it with this reply again.
Thank you I got it.
Problem is that when I log in in my profile I can not see attachments, but when I click the link in my e-mail and it opens before login they are there ?!
