Filter Type
Opens a submenu to select the filter type.
When measuring Spurious Emissions, using this softkey automatically opens the
"Sweep List" dialog (see "Sweep List dialog box" on page 289).
The submenu contains the following softkeys:
●
Normal (3 dB)
●
CISPR (6 dB)
●
MIL Std (6 dB)
Note that the 6 dB bandwidths are available only with option R&S FSV-K54.
●
Channel
●
RRC
●
5-Pole (not available for sweep type "FFT")
For detailed information on filters see Chapter 6.2.6.3, "Selecting the Appropriate Filter
Type", on page 366 and Chapter 6.2.6.4, "List of Available RRC and Channel Filters",
on page 367.

6.2.6.2 Specifying the Bandwidth
1. Set the resolution bandwidth using the Res BW Manual or Res BW Auto softkey.
2. Set the video bandwidth using the Video BW Manual or Video BW Auto softkey.
3. Set the sweep time using the Sweeptime Manual or Sweeptime Auto softkey.
4. Press the Filter Type softkey and select the appropriate filters.
6.2.6.3 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
For more information see Chapter 5.2.1, "Measurement Bandwidth", on page 166.
●
MIL Std (6 dB) filters
For more information see Chapter 5.2.1, "Measurement Bandwidth", on page 166.
