Hello, currently I am taking frequency response data from some switch mode power supplies over a range of 1-100kHz using an AP300 analyzer. My results give me 100 data points of frequency, Gain (magnitude in dB) and Phase (deg). I am trying to create a complex graph from these data points (Nyquist plot I believe it's called). My thought was for each data point I would take the Mag, convert it to non dB units (10^(dB/20)) and then the real part could be Mag*cos(Phase) and the imaginary part would be Mag*sin(phase). Then I would just plot these points on the real/imaginary axis. Is this correct thinking or am I going about this the wrong way?
