RF network analyzers are vital items of test instrumentation for RF design laboratories as well as many manufacturing and service areas.
Although 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.
The RF network analyzer provides a stimulus for the network and then monitors the response. In this way the operation and performance can be seen and assessed for its suitability.
RF network analyzers can be used for all RF and microwave frequencies - some network analyzers can operate well into the microwave region.
