 Network Analyzers using RVNA and RNVNA software

In this format, stimulus values are plotted along X-axis and the measured data are plotted along Y-axis (See figure below).

To display complex-valued S-parameters along the scalar Y-axis, it must be transformed into a real number. Rectangular formats involve various types of transformation of an S-parameter

,

where — real part of S-parameter complex value,

— imaginary part of S-parameter complex value.

There are eight types of rectangular formats depending on the measured value plotted along Y-axis (See table below).

The format for each trace of the channel can be selected individually. The trace must be activated before setting the format (See Active Trace Selection).

To set the trace display format use the following softkey Trace. In the Trace dialog select the required trace from Active Trace and click on Format softkey. Then select the required format in the Format dialog.
