About

Network analyzers are used mostly at high frequencies; operating frequencies can range from 1 Hz to 1.5 THz.[1] Special types of network analyzers can also cover lower frequency ranges down to 1 Hz.[2] These network analyzers can be used for example for the stability analysis of open loops or for the measurement of audio and ultrasonic components.[3]

The two basic types of network analyzers are

  • scalar network analyzer (SNA)—measures amplitude properties only
  • vector network analyzer (VNA)—measures both amplitude and phase properties

A VNA is a form of RF network analyzer widely used for RF design applications. A VNA may also be called a gain-phase meter or an automatic network analyzer.
