R&S FSH Network Analyzer Mode
Performing Vector Measurements (R&S FSH-K42)
Operating Manual 1173.6275.12 - 30 193
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.
