6 MEASUREMENT DATA ANALYSIS
201
To set the window shape for the specific β-parameter of
the Kaiser-Bessel filter, use the following softkeys:
Analysis > Time Domain > Window > Kaiser Beta
The available β values are from 0 to 13. 0 corresponds to
minimum window, 6 corresponds to normal window, 13
corresponds to maximum widow.
Note The impulse width and β of the Kaiser-Bessel filter are
the dependent parameters. When you set one of the
parameters the other one will be adjusted automatically.
6.4.5 Frequency Harmonic Grid Setting
If lowpass impulse or lowpass step transformation is enabled, the frequency range will
be represented as a harmonic grid. The frequency values in measurement points are
integer multiples of the start frequency Fmin. The Analyzer is capable of creating a
harmonic grid for the current frequency range automatically.
To create a harmonic grid for the current frequency
range, use the following softkeys:
Analysis > Time Domain > Set Frequency Low Pass
The frequency range will be transformed as follows:
Fmax > N x 0.3 MHz Fmax < N x 0.3 MHz
Note
Fmin = Fmax / N Fmin = 0.3 MHz,
Fmax = N x 0.3 MHz
