The Siglent SVA1075X spectrum and network analyser is the 7.5 GHz version in Siglent's SVA1000X series. Because the analyser is equipped with an enormous bandwidth of 7.5 GHz, the SVA1075X can perform measurements on almost all signals. A striking feature of this analyser is the low noise that affects the signal. Only -165 dBm/Hz is the typical noise the analyser experiences. This is low enough not to notice it in practice.
Thanks to the large 10.1" touchscreen display, the SVA1075X can be easily controlled and signals can be analysed in detail. Thanks to its high bandwidth and low DANL, the SVA1075X is also ideal for all EMC pre-compliance applications. We also offer specialized software for this purpose, which you can find at the bottom of the page. The scope also contains a Webcontrol function.
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). In the case of a VNA, both the amplitude and the phase (S11 and S21) of the signal are determined.
EEVblog has made a video about the SVA1015X with examples and explanations of the VNA function, which you here you can watch.
