Which of the following can be measured by a two-port vector network analyzer?

  1. Phase noise
  2. Filter frequency responseՃիշտ պատասխան
  3. Pulse rise time
  4. Forward power

Բացատրություն

A two-port vector network analyzer measures the magnitude and phase of transmission across a swept frequency range, which is exactly what a filter's frequency response is. Phase noise, pulse rise time and absolute forward power describe a source's own behaviour rather than a device's response to the analyzer's stimulus.
