Optimizing Measurements
Increasing Network Analyzer Dynamic Range
To
Reduce
the
Receiver
Noise
Floor
Receiver dynamic range is the difference between the analyzer’s maximum
allowable input level and its noise floor.
Changing System
Bandwidth
Reducing the system bandwidth lowers the noise floor by digitally reducing
the receiver input bandwidth. As system bandwidth is reduced, more
receiver measurements are used per frequency point, increasing the sweep
time. However with system bandwidth reduction,
unlike
averaging, only one
sweep is required for the reduced noise floor effect.
The analyzer offers a choice of six system bandwidths: wide, medium wide
(default setting), medium, medium narrow, narrow, and fine.

2. Press the key that corresponds to the bandwidth you want.
NOTE
It is recommended that wide system bandwidth only be used for broadband detection measurements
due to trace noise effects.
