The icon indicates that an error or warning is available for that measurement chan-
nel. This is particularly useful if the MultiView tab is displayed.
The icon indicates the currently active channel during an automatic measurement
sequence (

functionality).
Channel-specific settings
Beneath the channel name, information on channel-specific settings for the measure-
ment is displayed in the
channel bar
. Channel information varies depending on the
active application.
In the Spectrum application, the R&S
FSMR3 shows the following settings:
Table 4-6: Channel settings displayed in the channel bar in the Spectrum application
Ref Level
Reference level
m.+el.Att
Mechanical and electronic RF attenuation that has been set.
Ref Offset
Reference level offset
SWT
Sweep time that has been set.
If the sweep time does not correspond to the value for automatic coupling,
a bullet is displayed in front of the field. The color of the bullet turns red if
the sweep time is set below the value for automatic coupling. In addition,
the UNCAL flag is shown. In this case, the sweep time must be increased.
For FFT sweeps, an estimated duration for data capture
and processing
is
indicated behind the sweep time in the channel bar.
Meas Time
/
AQT
Measurement (acquisition) time, calculated from analysis bandwidth and
number of samples (for statistics measurements)
RBW
Resolution bandwidth that has been set.
If the bandwidth does not correspond to the value for automatic coupling,
a green bullet appears in front of the field.
VBW
Video bandwidth that has been set.
If the bandwidth does not correspond to the value for automatic coupling,
a green bullet is displayed in front of the field.
AnBW
Analysis bandwidth (for statistics measurements)
Compatible
Compatible device mode (FSP, FSU, default; default not displayed)
Mode
Indicates which sweep mode type is selected:
●
"Auto FFT": automatically selected FFT sweep mode
●
"Auto sweep": automatically selected swept sweep mode
●
"Sweep": manually selected frequency sweep mode
●
"FFT": manually selected FFT sweep mode
Icons for individual settings
A bullet next to the setting indicates that user-defined settings are used, not automatic
settings. A green bullet indicates this setting is valid and the measurement is correct. A
red bullet indicates an invalid setting that does not provide useful results.
