Problems to compare impedance AD5933 and Agilent LCR meter E4980A
Hello, I´m currently working with the impedance converter AD5933. I´m having some problems to compare the data that I get from the AD5933 with a LRC meter. I start my measurement by configurating my frequency start, the increment and number of increments. In my
What measurement setup of the AD5933 are you using? My setup is a AD5933 eval board on which I had to place a gain resistor RFB of 10k. In the attachment you can see the measurement of a 10k resistor. The calibration was done with

16 bit division with high precision problem?
Hi, all I use mega128 to control ad5933 chip, since now it's the last step of my whole project, sticking with assembly language is a better option. I am doing damage matrix between two column of data, after I simplified the equation,
