7.2.5 Amplitude Settings
Amplitude settings determine how the R&S FSMR3000 must process or display the
expected input power levels.
Reference Level .......................................................................................................... 141
└ Shifting the Display (Offset) .......................................................................... 142
RF Attenuation ............................................................................................................ 142
└ Attenuation Mode / Value ..............................................................................142
Input Settings .............................................................................................................. 142
└ Preamplifier ...................................................................................................142
Reference Level
Defines the expected maximum reference level. Signal levels above this value are pos-
sibly not measured correctly. Signals above the reference level are indicated by an "IF
Overload" status display.
The reference level can also be used to scale power diagrams; the reference level is
then used for the calculation of the maximum on the y-axis.
Since the hardware of the R&S FSMR3000 is adapted according to this value, it is rec-
ommended that you set the reference level close above the expected maximum signal
level. Thus you ensure an optimum measurement (no compression, good signal-to-
noise ratio).
