Setting the reference level
The level at the top of the measurement diagram is called the reference level. To
obtain the best dynamic range from the R&S Spectrum Rider, you should use its
full level range. That means that the maximum level value should be at or close to
the top of the measurement diagram (= reference level).
1. Press "REF" softkey at the "Parameter view".
The R&S Spectrum Rider opens an entry box to enter the reference level.
2. Enter a reference level of -25 dBm.
The R&S Spectrum Rider reduces the reference level by 5 dB.
The maximum trace value is close to the maximum scale value of the measure-
ment diagram. The increase in the displayed noise floor is minimal. The differ-
ence between the signal maximum and the displayed noise (i.e. the dynamic
range) has, however, been increased.
Using markers
The R&S Spectrum Rider has markers to read out signal levels and frequencies.
Markers are always positioned on the trace. Both the level and frequency at their
current positions are displayed on the screen.
