R&S ZVH Network Analyzer Mode (R&S ZVH-K42)
Evaluating the Results
Operating Manual 1309.6946.12 - 09 193
For vector measurements, you can also display two traces in each diagram. This
way, you can view four results at the same time (S11, S12, S21, S22). For more
information on how to configure such a screen layout, see "Measuring the
Transmission".

After activating the second trace, trace 1 is always the active trace. Only the active
trace can be configured, while the other is passive.
► To activate trace 2, press the "Select Trace" softkey in the trace menu.
When pressing the "Select Trace" softkey, the R&S ZVH switches between trace 1
and 2. The trace indicator shows the currently active trace:
After selecting trace 2, you can set the measurement parameters for trace 2, while
the first trace is passive.
Note that you can display all four S-parameters at the same time in dual trace
mode by displaying the transmission measurement in both directions in one
window and displaying the reflection measurement on both ports in the other
window. For more information see "Performing Vector Measurements" on page
181.
Restoring a saved trace is possible only for the currently active trace (i.e. screen 1 or
screen 2). For more information see "Working with Memory Traces" on page 144.
