Optimizing Measurements
Increasing Network Analyzer Dynamic Range
To Reduce the Receiver Noise Floor
Receiver dynamic range is improved by reducing the system bandwidth
and by increasing the averaging factor.
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.
1. Press
.
2. Press the key that corresponds to the bandwidth you want:
AVG
System Bandwidth
Wide 6500 Hz
Med Wide 4000 Hz
Medium 3700 Hz
Med Narrow 1200 Hz
Narrow 250 Hz
Fine 15 Hz
