2.7.2.1 Selection
Selection
should be set to Constant if one Loss Input value is to be used for all
frequencies. In this case, the
Loss Input Constant
value will be used across the entire
frequency range and the Loss Input List will be ignored.
When
Selection
is set to Table, R&S FS-K30 will use the table of Loss Input values at
the bottom left of the view to calculate the Loss Input value to be used for each specific
RF
frequency at which a measurement is performed. The
Loss Input Constant
value
will be ignored and will not be selectable.
2.7.2.2 Loss Input Constant
Loss Input Constant
is the constant Loss Input value that is to be used across the
entire frequency range.
This parameter is only available when
Selection
is set to Constant.
2.7.3 Loss Input Table
The
Loss Input Table
lists the Loss Input values for different Receive Frequency (
RF)
values. R&S FS-K30 will interpolate between points in the list for
RF
values used in a
measurement that are not explicitly entered in the Loss Input Settings list.
When focus is moved to the Loss Input table at the bottom left of the view, the current
parameter in the table is highlighted. Navigation through the table is possible in all four
directions using the cursor keys.
It is possible to add individual values directly into the Loss Input List, including insertion
and deletion of
RF/Loss Input
value pairs (rows in the list). The list can contain up to
100
RF/Loss Input
value pairs. Note that the order of
RF
values in the list is not
important.
Loss Input tables can also be saved and recalled at any time by pressing the
FILES
hardkey. This allows specific Loss Input tables to be saved for later use. Refer to
section “
for details of how to use Save & Recall.
