Equalizer screens
The VS300’s exciter includes a fixed equalizer to optimize audio performance. There are three
menus available in the tool panel -
EQ Frequency
,
EQ Impulse Response
and
EQ Filter Delay
.
Coefficients are selected based on your channel frequency. All frequencies shown are relative
to the channel frequency.
Figure 2.25: EQ Frequency Response
EQ frequency response
See Figure 2.25. This panel displays the frequency response of the modulator’s EQ filter.
Click on the panel to display a cursor in the approximate area. The cursor position (magnitude
and amplitude) is noted in the upper, right-hand corner of the panel. Click in other areas of the
panel to provide a coarse adjustment of the cursor position.
Note:
The FM spectrum analyzer displays the ideal spectrum generated by the DSP. It is
not necessarily the same as the spectrum seen at the RF output.
