ACP Measurement
Meas Setup
Power Ref
Sets the power reference in the carrier that will be used to compute the relative values for the offsets.
Total Power
Sets the multi-carrier power reference.
When set to Auto, the carrier power result reflects the measured power value in the selected reference
carrier.
When set to Man, the result is referenced to the last measured value, or you may specify the reference for
the multi-carrier power measurement. Relative values are displayed, referenced to the “Power
Couplings Coupled to the Center Frequency.
If the center frequency changes, the Ref Carrier Frequency is calculated using
the following three steps;
Ref Freq1 = Ctr Freq - (Total of all Carrier Widths / 2)
Ref Freq2 = Ref Freq1 + (Total of all Carrier Widths up to Ref Carrier)
Ref Freq = Ref Freq2 + (0.5 * Carrier Width of Ref Carrier)
If reference carrier frequency changes the Center Frequency is calculated
using the following three steps;
Ctr Freq1 = Ref Freq - (0.5 * Carrier Width of Ref Carrier)
Ctr Freq2 = Ctr Freq1 - (Total of all Carrier Widths up to Ref Carrier)
Ctr Freq = Ctr Freq2 + (Total of all Carrier Widths / 2)
This ensures that the carriers are always centered on the screen.
If there is only one carrier present the Reference Carrier Frequency will be the
same as the Center Frequency.
