Gain factor in real Resistance and Reactance (AD5933)
If you do the math with real numbers you should see it comes to the same final number.


Sorry, but I didn't understand.

For example, in the Datasheet of the AD5933 there is the following example:

Gain Factor = 515,819 x 10 ^ (-12)

Real data register = -1473

Imaginary data register = 3507

So, the Magnitude of the impedance is:  3802,863

Then, applying the gain factor, the correct Magnitude of the impedance is: 509,791 k

.



My point is:

If I just multiply the values of the registers -1473 and 3507 with the gain factor (515,819 x 10 ^ (-12)), and calculate the correct Magnitude of the Impedance:



I can't get the correct impedance value, which was previously calculated 509,791 k.
