A unique feature is the chapter on . Basso details how to use a network analyzer (like the AP300 or Omicron Bode 100) to inject a signal via an isolation transformer and measure the actual Bode plot. He warns about common pitfalls: probe ground loops, injection level non-linearity, and the effect of the transformer’s low-frequency roll-off. , which describes how a small change in
