A network analyzer is an instrument that measures the network parameters of electrical networks.

• Characterisation of Two port network such as Filter , amplifier by measuring S-parameter ,
• Y- Parameter, H-parameter.
• High frequency measurements from 5 Hz to 1.05 THz.
• Low frequency measurements upto 1 Hz.
• Sound and Vibration Measurement.
• Scalar network analyser used to measure only amplitude property.
• Vector network analyser used to measure amplitude and phase property.
• Large signal network analyser used to measure amplitude and phase of large signal (fundamental and harmonics)
