Notes/Equations
  1. This subnetwork model measures the average power of the specified slots.
    The average period is one slot; SlotNum specifies the number of slots to be measured.
    Test signals are aligned at the specified slot boundary to ensure that the power average is based on a single slot.
    The schematic for this subnetwork is shown in the following figure.

  2. Refer to WCDMA3G_RF_PowMeas for more information.
  3. Use of this model is demonstrated in base station and user equipment transmitter examples: File > Example Project > WCDMA3G > WCDMA3G_BS_Tx_prj > BS_Tx_MaxPower.dsn and WCDMA3G_UE_Tx_prj > UE_Tx_MaxPower.dsn. Simulation results are provided in Data Display windows for these designs.
