6.1.2.1 Defining the Scan Range
The scan range defines the frequency range that the scan takes place in. Therefore,
you have to define a start and stop frequency for the scan range and a scan step size.
The step size defines the (equidistant) space between the receive frequencies and
thus, in combination with the start and stop frequency, the number of receive
frequencies considered in the scan.
Example:
If you define a scan range from 100 MHz to 200 MHz with a step size of 10 MHz, the
receive frequencies that are analyzed are 100 MHz, 110 MHz, 120 MHz, …, 200 MHz.
Overall, this scan range defines a set of 11 receive frequencies.
M
Press the SPAN key.
M
Press the "Scan Start" softkey.
Enter the frequency you want the scan to start at.
M
Press the "Scan Stop" softkey.
Enter the frequency you want the scan to stop at.
M
Press the "Scan Step" softkey.
Enter the step size you want to apply. The R&S FSH starts the scan as soon as
you have finished defining the scan range.
Performing a channel scan
Instead of a frequency scan, you can also perform a channel scan. A channel scan is
based on the contents of a channel table. In case of measurements based on a
channel table, the set of receive frequencies (or channels) is defined in a channel
table.
In a channel table, you can define the
receive frequencies as you wish. The
number of receive frequencies
depends on the number of channels
included in the channel table and there
may even be gaps between the
receive frequencies.
M
Press the FREQ key.
M
Press the "Channel Mode" softkey.
or
M
Press the "Channel Table" softkey.
The R&S FSH opens a dialog box to select the channel table.
