2.2.2.3 Setting the Frequency Range for CAT Measurements (except DTF)
If you measure the reflection, transmission or cable loss, the displayed frequency
range is defined by the span, the center frequency or start and stop frequencies.
Defining the span
The span you should select depends on the frequency band you are analyzing and the
frequency range you need information about.
The minimum span for both measurements is 10 Hz, the maximum span depends on
the R&S ZVH and is either 3.6 GHz (R&S ZVH4) or 8 GHz (R&S ZVH8).
► Press the FREQ/DIST key.
► Press the "Span" softkey.
► Enter the span you need.
The R&S ZVH sets the span you have entered.
Setting the displayed frequency range
In the default configuration, the R&S ZVH adjusts the start and stop frequency
according to the span and the center frequency, with the center frequency being in the
middle of the horizontal axis. Alternatively, you can directly set the start and stop
frequency.
► Press the FREQ/DIST key.
► Press the "Center" softkey.
► Enter the center frequency you need.
Alternatively, set the frequency range independent of span and center frequency.
► Press the FREQ/DIST key.
► Press the "Start" softkey and enter a start frequency.
► Press the "Stop" softkey and enter a stop frequency.
2.2.2.4 Selecting a Signal Standard for CAT Measurements (except DTF)
When you measure the reflection, transmission or cable loss. the R&S ZVH provides
several configurations for measurements on a particular signal standard. When you
select one of these, the R&S ZVH loads the corresponding parameters like center
frequency or span and you do not have set those anymore.
► Press the FREQ/DIST key.
► Press the "Signal Standard" softkey.
► Select either the "Select Uplink" or "Select Downlink" menu items.
The R&S ZVH opens a dialog box to select the standard.
► Select the standard you need.
The R&S ZVH loads the settings of the standard you have selected.
