1 = detectors
3 = measured levels (numerically)
4 = measured levels (graphically)
The results in the bargraph are shown as soon as you enter the receiver application
(for the frequency that is currently selected) and are updated continuously. The unit of
the displayed power level is variable and depends on the unit you have set (by default,
it is dBµV).
The bargraph range is always 100
dB, the minimum and maximum levels that are dis-
played are automatically adjusted, depending on the measurement configuration.
When auto ranging has been turned off, the range depends on settings like the attenu-
ation or gain. When auto ranging has been turned on, the range is adjusted to the sig-
nal level.
The R&S
ESW supports the simultaneous use of up to four different detectors in the
bargraph result display. If you select an additional detector, the R&S
ESW adds the
corresponding number of bargraphs to the result display. This way to display the signal
levels provides an easy way to compare the signal level with different weighting fac-
tors.
Meaning of small vertical lines in the bargraph
Depending on the configuration, the following small vertical lines can appear in the bar-
graph.
●
A small vertical line with the same color as the bargraph shows the highest value
that has been measured on the currently selected frequency.
●
A small red vertical line with an "SQ" label shows the
that you have
defined for audio output over headphones.
Max hold bargraph
The max hold bargraph information, when it has been turned on, shows the highest
signal level that has been measured since the measurement has begun. The max hold
value remains effective, even if you change any receiver settings (for example the fre-
quency or the attenuation) and is only reset when you deliberately do so. One max
hold value is displayed for each of the active detectors.
When you turn on the max hold information, the diagram information is expanded by
the peak level that has been measured since the max hold has been last reset (as a
numerical value and including the frequency that value has been measured on). If a
new peak level has been detected, the max hold values are updated accordingly.
The live results and the highest signal level for a particular frequency are still shown in
the bargraph diagram as usual.
