Rectangular window width adjustment

[senmeis]

Hi,

How to adjust the rectangular window width of a filter in simulator if the following parameters can be set accordingly?

 Loss: Magnitude loss in dB
 SymbolRate: Symbol rate (passband edge frequency = SymbolRate/2)
 RollOff: Roll-off factor (between 0 and 1)
 SquareRoot: Square root option: NO, YES
 PulseEqualization: Pulse equalization option: NO, YES
 LengthOption: Filter length option (Auto: 8 * symbol period): Auto, Number of Taps, Number of Symbols, Impulse Time Duration
 Length: Filter length (length = 2*delay) (based on LengthOption, specify number of taps, number of symbols, or impulse time duration)
 Window: Window function: Rectangular, Bartlett, Hann, Hamming, Blackman, Flat Top
 Interpolation: Interpolation (up sampling) factor
 Decimation: Decimation (down sampling) factor
 DecimationPhase: Decimation (down sampling) phase
 InterpolationScaling: Gain adjustment for interpolation: NO, YES

Maybe if you gave some context. Like WHAT SOFTWARE ARE YOU USING????

Maybe the window width is fixed by the Filter Length. Maybe not.

I’m using SystemVue from Keysight. I think the window length is a time domain issue so maybe “Impulse Time Duration” shall be configured, but what is “Number of Symbols”?
