The main function of the signal source in the network analyzer is to provide the incident signal which excites the device under test which is also known as DUT.

Network Analyzer Block Diagram Signal Source This block diagram mainly includes four essential components like signal source, signal separation, receiver or detector, and processor or display. The block diagram of this analyzer is shown below.

Scattering parameter measurements are used to measure s-parameters like S11, S12, S21 & S22.

Reflection measurements are used to measure VSWR, reflection coefficient, impedance & return loss.

Transmission measurements are used to measure insertion loss, gain, and transmission coefficient.

Network analyzer measurements are three types transmission, reflection, and scattering parameter.

These analyzers can also be used for the analysis of stability for the measurement of ultrasonic, audio components, and open loops. The operating frequencies of these analyzers range from 1 Hz – 1.5 THz. Transmission measurements comprise gain, insertion loss, transmission coefficient whereas reflection measurements comprise return loss, reflection coefficient, impedance, etc. It is used in transmission & reflection measurements.

Generally, these devices are used for different parts measurements like filters, mixers, frequency sensitive networks, transistors & other RF-based devices. So that the operator can monitor how the network or device functions in an RF circuit.

Generally, a network analyzer has the capacity to understand different protocols, which allows it to show conversations occurring between hosts over a network.Ī network analyzer characterizes & measures the device or network response. A network analyzer provides information regarding what is happening on a network by letting you observe the actual data that supplies packet by packet over it.
