The Siglent SVA1015X spectrum and vector network analyser has an excellent price/quality ratio, as it has a frequency range of up to 1.5 GHz and has the functions of a vector network analyser. This spectrum analyser has a large 10.1" LCD display and is equipped with advanced measurement functions. This spectrum analyser has a preamplifier, which means that the average noise experienced by the device is -156 dBm/Hz. This analyser comes standard with support for a tracking generator. There are also options available for this spectrum analyser to meet your requirements and preferences.
Update! The SVA1015X is now delivered with VNA license by default.
With the VNA you can determine the performance of radio frequency and microwave equipment by means of reflection and transmission coefficients. These performances are displayed in S-parameters (scattering parameters, more information on these parameters can be found at Wikipedia). In the case of a VNA, both the amplitude and phase (S11 and S21) of the signal are determined.
EEVblog also made a video about the SVA1015X with examples and explanations of the VNA function, which you can view here.
