To perform the measurements, you inject a small AC signal into the power supply’s control-loop circuit and measure the loop’s gain and phase shift. By measuring the gain and phase, you can plot them ...

Using a Bode Plotter on the passive component network alone, I saw what I was hoping to see: a sharp peak in the transfer function at the correct frequency—in this case at approximately 1.6 MHz. The ...

A frequency response analyzer (‘FRA’) is often used to measure gain and phase plots of control loops (Bode plots), filter responses and general frequency domain transfer functions.
