Distance to the limit line, if a limit line is active.
If a second trace is active, the peak list shows the highest peaks of both traces.
15.1.3 Max Hold Information
Access : "Meas"
Both the bargraph measurement and the frequency scan contain max hold information.
Max hold information indicates the highest level that has been measured since you
have started the measurement.
In the bargraph measurement, the R&S FPC displays the highest level that was mea-
sured, 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 signal level
of 100 dBµV at the new frequency, the highest measured level will still be 100 dBµV.
In the frequency scan, the R&S FPC 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.
15.2 Frequency Configuration

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.
