Setting the Video Bandwidth
Selecting a bandwidth value close to or slightly greater than required by the
modulating signal bandwidth can help reduce noise and improve accuracy on
peak measurements (see Table 2-3). It can however, reduce the processing speed
for long acquisition times.
Table 2-3 P-Series Sensor Video Bandwidth Setting
The Low, Medium, and High pass band shapes achieved by the video bandwidth
settings provide flat filter responses with very sharp cut-off points by applying
digital signal processing techniques to ensure accurate power measurement
within the specified band.
This feature is only available when a P-Series or an E-Series E9320 power sensor
is connected.
