Example 7: Stimulus-Response Measurements
Figure 2-39 NORM REF LVL adjusts the trace without changing analyzer
settings.
RANGE LVL increases the dynamic range of the measurement by
changing the input attenuator and IF gain. It is equivalent to
REF LVL
used in signal analysis measurements. Both RANGE LVL and REF LVL
ensure that the input signal is not in gain compression.
To increase the dynamic range of the measurement, press
RANGE LVL.
Note that while increasing the dynamic range, more errors are
introduced into the measurement, such as attenuator switching.
However, as Figure 2-40 shows, the dynamic range level has increased
by 18 dB, when using
RANGE LVL.
