An S-parameter can be displayed in different formats, as already described. The Site Master also allows you to extract information from the trace by using 8 markers. By default, the marker presents the trace point information using the graph type format, thereby providing additional flexibility in analyzing S-parameter VNA data. For example, if the graph type is SWR, then the marker readout is in SWR. You can set the marker type to be something other than the graph type. Refer to

For any graph type that the trace may have, the markers can be used to extract data in any of the following formats:

Another important feature of a VNA is the ability to provide DC bias voltage at the RF port. Bias on the RF cable is useful for operating TMA components that are being tested. Refer to SETUP Menu.
