Power Control

This topic shows the DPCH external power control signals.

Figure 1 shows how the external power control feature is implemented.

Figure 1 DPCH Power Control

Figure 2 illustrates the DPCH power control using an external signal. When the Power Hold State is turned off, the instrument's output responds to the power control trigger signal. The transmit power control signal is sent from the base station and indicates whether to increase or decrease the power level. Increases and decreases are done in increments of the specified Power Step. Once the power level has reached the specified Maximum Power, signals requesting an increase in the power level will be ignored (the power is clipped to Maximum Power).
