3.10.1 Selecting the Appropriate Filter Type
All resolution bandwidths are realized with digital filters.
The video filters are responsible for smoothing the displayed trace. Using video band-
widths that are small compared to the resolution bandwidth, only the signal average is
displayed and noise peaks and pulsed signals are repressed. If pulsed signals are to
be measured, it is advisable to use a video bandwidth that is large compared to the
resolution bandwidth (VBW * 10 x RBW) for the amplitudes of pulses to be measured
correctly.
The following filter types are available:
●
Normal (3dB) (Gaussian) filters
The Gaussian filters are set by default. The available bandwidths are specified in
the data sheet.
●
CISPR (6 dB) filters
●
MIL Std (6 dB) filters
Note that the 6 dB bandwidths are available only with option R&S FSV-K54.
●
Channel filters
For details see
on page 64 .
Channel filters do not support FFT mode.
●
RRC filters
For details see
on page 64 .
RRC filters do not support FFT mode.
●
5-Pole filters
The available bandwidths are specified in the data sheet.
5-Pole filters do not support FFT mode.
3.10.2 List of Available RRC and Channel Filters
For power measurement a number of especially steep-edged channel filters are availa-
ble (see the following table). The indicated filter bandwidth is the 3 dB bandwidth. For
RRC filters, the fixed roll-off factor (a) is also indicated.
