In addition, you can display two diagrams, so that you can view all four results at the
same time (S11, S12, S21, S22).
► Press the TRACE key.
► Press the "Split Screen” softkey.
► Press the "Select Trace" softkey to
select the diagram.
► Trace 1 corresponds to the upper
diagram (contains trace 1 and
trace 3).
► Trace 2 corresponds to the lower
diagram (contains trace 2 and
trace 4).
► Select the contents from the "Measurement” menu as required.
When you are measuring with two diagrams, you can configure the scale of the y-axis
for each diagram separately, depending on the trace you have currently selected. You
can also select a different measurement format for each diagram (phase, magnitude
etc.). Markers on the other hand are coupled. When you move them, they change the
position in both diagrams. See also "
Working with the Dual Trace Mode
".
Define the frequency parameters
Before calibrating the measurement, you should define the frequency parameters to
avoid interpolation of the results.
► Press the FREQ key.
The R&S FSH opens an input field to set the center frequency.
► Enter a frequency of 1950 MHz.
► Press the SPAN key.
The R&S FSH opens an input field to define the span.
► Enter a span of 130 MHz to get a high resolution of the results.
