Large Signal Network Analyzer (LSNA): The large signal network analyzer, LSNA is a highly specialised for of RF network analyser that is able to investigate the characteristics of devices under large signal conditions.As a result VNA network analyzer may also be called a gain-phase meter or an Automatic Network Analyzer. Not only does the it measure the amplitude response, but it also looks at the phase as well. Vector network analyzer (VNA): The VNA network analyzer is a more useful form of RF network analyzer than the SNA as it is able to measure more parameters about the device under test.In view of this it is the simpler of the various types of analyser.

Scalar network analyzer (SNA): The scalar network analyzer, SNA is a form of RF network analyzer that only measures the amplitude properties of the device under test - i.e.These types of RF network analyzer are very different, but they are all able to measure the parameters of RF components and devices but in different ways:

Within the broad scope of RF network analyzers, there are various types of instrument which can be bought and used. Typical high end vector network analyzer, VNA in use Types of RF network analyzer RF network analyzers can be used for all RF and microwave frequencies - some network analyzers can operate well into the microwave region. In this way the operation and performance can be seen and assessed for its suitability. The RF network analyzer provides a stimulus for the network and then monitors the response. RF network analyzers are vital items of test instrumentation for RF design laboratories as well as many manufacturing and service areas.Īlthough mainly focussed on research and development, RF network analyzers are able to provide vital insights into the operation and performance of RF networks of all types.
