By editing individual values in the Frequencies List on the right, including insertion and
deletion of measurement steps. This allows specific adjustments to individual
measurement steps to be made in order to customise the automatically generated list,
e.g. to insert extra measurement steps near to a specific frequency of interest in order to
get more detailed results (but without losing the rest of the frequency range).
Note that when any change is made to the Frequencies List, R&S FS-K30 will need to
be calibrated again.
2.4.1 Frequency Settings
The parameters in the Frequency Settings group are used to automatically generate the list
of Receive Frequency (
RF
) values for the Frequencies List shown on the right of the
settings view.
The
RF
values in the Frequencies List are generated into a list of ascending frequencies as
follows (when the
Start Frequency
is less than the
Stop Frequency
):
1. Start Frequency
2. Start Fre Step Frequency
3. Start Fre Step Frequency * 2
4. Start Fre Step Frequency * 3
…
n.
Stop Frequency
If the
Start Frequency
is larger than the
Stop Frequency
, then the
RF
values will be
generated into a list of descending frequencies with the
Step Frequency
being
subtracted for each step.
If the values for
Start,
Stop & Step
Frequency
will result in a Frequencies List of more than
100 measurement steps, only the first 100
RF
steps will be generated and a warning
will be displayed to the user (See Section 4). Reduce the gap between the
Start & Stop
Frequencies
or increase the
Step Frequency
to reduce the list to 100 points or less.
If the Single Frequency measurement is selected Start and Stop frequencies are
always identical and the list reduced to one element, allowing to quickly run a
measurement at one specific frequency. The Stop and Step Frequency fields are
disabled and the Stop Frequency follows changes made to the Start Frequency.
2.4.1.1 Start Frequency
The
Start Frequency
will be the frequency at which the Frequencies List starts, that is,
the first Receive Frequency (
RF
) in the list.
Changing the
Start Frequency
will regenerate the list of measurement steps, using the
measurement
Mode
selected.
