|
What does it do? |
Spectrum analyzers are used to test RF/microwave or modulated signals. They primarily provide frequency domain analysis of radio signals, as well as distortion, interference and demodulation analysis of signals of interest. |
A signal generator provides a clean signal which can be used as a local oscillator (LO), a stimulus signal with or without modulation, as an interference source, and more. |
A vector network analyzer (VNA) measures S-parameters of the device under test, such as return loss, VSWR, insertion loss or group delay. |
|
Where is it used? |
Mainly used in RF/microwave transmitter/transceiver module characterization. Also widely used in signal monitoring, spectrum surveillance, and EMI precompliance test. |
Primarily used in receiver testing but also in development of RF components/devices, any application which requires a controlled signal source with specific parameters and qualities. |
A VNA is used to measure components, devices, circuits and sub-assemblies. |
