● "Trace Style: Polygons": Shows the trace as a continuous, horizontal line. The
gaps between the measurement frequencies are interpolated.
10.1.3 Max Hold Information
Access
: "Meas"
Both the fixed frequency measurement and the frequency scan contain max hold infor-
mation. Max hold information indicates the highest level that has been measured since
you have started the measurement.
In the fixed frequency measurement, the R&S
FPC1000 displays the highest level that
was measured, regardless of the selected frequency. If, for example, you first measure
a signal level of 110 dBµV at 100 MHz, then change the frequency and measure a sig-
nal level of 100 dBµV at the new frequency, the highest measured level will still be
100 dBµV.
In the frequency scan, the R&S FPC1000 displays the highest level for all frequencies
that are part of the frequency range. The max hold information is indicated by a blue
line that is appended to the yellow line (which indicate the current signal level).
The max hold information is displayed for both frequency modes (frequency display
and channel display).
Resetting the max hold
To begin a new max hold measurement, you have to reset the max hold information
deliberately.
1. Press the "Meas" key to open the measurement menu.
2. Select the "Refresh Max Hold" menu item.

Chapter 13.11.2, "Frequency" , on page 230
The frequency configuration in the receiver application depends on the measurement
you have selected.
In case of a fixed frequency scan, you define a single receiver frequency that is ana-
lyzed.
In case of a frequency scan, you define a frequency range and a stepsize. The combi-
nation of both defines the frequencies that are measured during the scan.
