2.16.3.3 Ref Carrier Freq
The Ref Carrier Freq setting determines whether the Ref Carrier Freq is calculated based on
the Center frequency (Auto) or the Center frequency is calculated based on the Ref Carrier
Freq (Man). The Ref Carrier Freq value will always be updated if the Ref Carrier Freq
setting is changed, whether the Mode is set to Auto or Man.
If Ref Carrier Freq is set to auto, it is assumed that the carriers are distributed evenly
around the current center frequency. In this case the following three steps are used to
calculate the Ref Carrier Freq value and the calculated Ref Carrier Freq is shown on the
Ref Carrier Freq key:
1. Ref Freq 1 = Cntr Freq − [(Total of all Carrier Widths)/2]
2. Ref Freq 2 = Ref Freq 1+ (Total of all Carrier Widths excluding the Ref Carrier Width)
3. Ref Freq = Ref Freq 2 + [0.5 (Carrier Width of Ref Carrier)]
The Ref Carrier Freq can also be entered by the user. This will set the Ref Carrier Freq to
Man and the Center frequency of the analyzer will be calculated using the following three
steps:
1. Cntr Freq 1 = Ref Freq − [0.5 (Carrier Width of Ref Carrier)]
2. Cntr Freq 2 = Cntr Freq 1 − (Total of all Carrier Widths excluding the Ref Carrier
Width)
3. Cntr Freq = Cntr Freq 2 + [(Total of all Carrier Widths)/2]
The above algorithms ensure that the carrier is centered on the analyzer display.
