5.19.3.3 Ref Carrier Freq
Press
Ref Carrier Freq (Man) to select the reference carrier frequency for this measurement.
The center frequency is then calculated using the algorithm below:
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]
Pressing
Ref Carrier Freq (Auto) distributes the carriers evenly around the current center
frequency. The reference carrier frequency is then calculated using the algorithm below:
1. Ref Freq 1 = Cntr Freq [(Total of all Carrier Widths)/2]
2. RefFreq2=RefFreq1+ (Total of all Carrier Widths excluding the Ref Carrier Width)
3. Ref Freq = Ref Freq 2 + [0.5 (Carrier Width of Ref Carrier)]
The above procedure ensures carrier visibility on the analyzer display.
Key Path:
Meas Setup, Carrier Setup
Dependencies/
Couplings: The reference carrier can be re-assigned by implementing changes to
carrier power present values.
State Saved: Saved in instrument state.
Factory Preset: Auto/Calculated based on current center frequency. Refer to the
“algorithm” above when defining the Ref Carrier Freq(Auto) key.
