User Manual 1178.4130.02 ─ 02
Compared to single frequency measurements, frequency scans measure a certain set
of receiver frequencies. The scan measures only those frequencies that are defined in
. The space between the receiver frequencies is not considered in
the measurement.
The R&S
FPC1000 shows the results for a frequency scan in a graphical result display.
The horizontal axis in that display represents the frequency spectrum covered by the
scan. The vertical axis represents the signal level.
The signal levels for each frequency measured during the scan are represented by a
vertical line at the receiver frequencies that have been measured. This type of display
emphasizes the fact that the scan measures single receiver frequencies only and not
the frequencies between those receiver frequencies.
Yellow lines represent the current signal level. Blue lines represent the highest level
that has been measured since the measurement was started (
information).

Selecting frequency scans
1. Press the "Meas" key to open the measurement menu.
2. Select the "Frequency Scan" menu item.
The R&S
FPC1000 shows the scan diagram. For each measured frequency, it
shows a vertical bar.
Selecting the trace style
The trace style defines the way the trace looks.
1. Press the "Trace" key to open the trace menu.
2. Select the trace style.
● "Trace Style: Lines": Shows a vertical line for each receive frequency as descri-
bed above.
