Equalizer Selection (Positive Equalization Value)
Select an equalizer from the appropriate equalizer table in Accessory Tables on page D-6 that has a
tilt as close as possible to the desired Equalization Value. If the desired equalizer value is at the
midpoint between equalizer values, select the equalizer with the lower value. When selecting an
equalizer, be sure to account for the accessory's tilt. The tilt for a particular accessory is calculated
as follows:
For example, if you calculated an Equalization Value of 2 dB, then you need an SEQ-1G-03 equalizer
because:
Cable Simulator Selection (Negative Equalization Value)
Select a cable simulator from the appropriate table in Accessory Tables on page D-6 that has a tilt as
close as possible to the desired Equalization Value. If the desired equalizer value is at the midpoint
between equalizer values, select the equalizer with the lower value. When selecting an equalizer, be
sure to account for the accessory's tilt. The tilt for a particular accessory is calculated as follows:
For example, if you calculated an Equalization Value of –2dB, then you would need an SCS-1G-03
cable simulator because:
