سؤال 173

Which of the following must be connected to an antenna analyzer when it is being used for SWR measurements?

  1. Receiver
  2. Transmitter
  3. Antenna and feed lineپاسخ درست
  4. All these choices are correct

توضیح

An antenna analyzer contains its own signal source and impedance bridge, so it needs nothing from the station transmitter or receiver; what it needs is the load whose impedance is being measured, meaning the feed line and the antenna it feeds. Connecting a transmitter as well would in fact damage the analyzer.
