Optimization Calculations for Plugins

When using conditioning taps or inline equalizers (LEQ/RC) in your design, consider the following points in terms of optimization.

• Optimization only runs on unlocked components.

• There are currently no rules for the auto-optimization of inline equalizers (LEQ/RC). The application only auto-optimizes conditioning taps and amplifiers.

  • Inline equalizers (LEQ/RC) behave similarly to taps in terms of adding plugin attenuation to the losses from the device. However, the plugin only applies to the return path. The forward path has a built-in equalizer that is listed in the loss levels of the device itself.

  • For inline equalizers (LEQ/RC), add pad value to the return loss on the return path, then add that to the input.

• Plugins only affect the tap losses. Through leg losses are unaffected by plugins.

  • Tap leg losses are the sum of the losses of the tap device itself and the plugin losses. All losses are measured/calculated at a specific frequency. Tap leg losses are subtracted from the input signal strength at their corresponding forward frequencies.

• Return attenuation/tap leg losses are added to the input signal strength at their corresponding return frequencies.

• If you use a jumper or “loss-less” plugin, you should see the losses defined in the conditioning tap’s tap leg loss section for a given frequency.
