This is because the transient response can be compensated because the filters have an accurately defined behavior. The highest sensitivity is obtained at the smallest bandwidth. If the bandwidth is increased, the reduction in sensitivity is proportional to the change in bandwidth.
- Page 34 ® Configuration R&S ESW-K55E and -K55R Bandwidth configuration You can define a different bandwidth for the bargraph and each scan range defined in the scan table.
