Question 178

Which of the following can be measured with an antenna analyzer?

  1. Velocity factor
  2. Cable length
  3. Resonant frequency of a tuned circuit
  4. All these choices are correctBonne réponse

Explication

All three follow from the analyzer's ability to measure impedance against frequency. A tuned circuit shows its resonance directly, and a length of line left open or shorted resonates at frequencies that reveal its electrical length, from which physical length or velocity factor is calculated.
