6.1 Measuring a Sinusoidal Signal
One of the most common measurement tasks that can be handled by using a sig-
nal analyzer is determining the level and frequency of a signal. When measuring
an unknown signal, you can usually start with the presettings.
High input values
If levels higher than +30 dBm (=1 W) are expected or are possible, a power
attenuator must be inserted before the RF input of the analyzer. If this is not
done, signal levels exceeding 30 dBm can damage the RF attenuator or the
input mixer. The total power of all occuring signals must be taken into
account.
