R&S FSH Receiver Mode (R&S FSH-K43)
Selecting the Measurement Mode
Operating Manual 1173.6275.12 - 30 236
Selecting the trace style
The trace style defines the way the trace looks.
► Press the TRACE key.
► Press the "Trace Style" softkey.
► Select the trace style you prefer from the menu.
The R&S FSH provides two trace styles in receiver mode.
● "Lines"
The "Lines" trace style shows a vertical line for each receive frequency as
described above.
● "Polygon"
The "Polygon" trace style shows the trace as a continuous, horizontal line. The
gaps between the actual measurement frequencies are interpolated.
8.1.2.1 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.
► Press the SPAN key.
► Press the "Scan Start" softkey.
Enter the frequency you want the scan to start at.
► Press the "Scan Stop" softkey.
Enter the frequency you want the scan to stop at.
► 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.
