Adjacent Channel Power Measurement

Adjacent Channel Power (ACP) is a measure of the power that leaks into adjacent transmit channels. The ACP measurement measures the power present in the transmit channel (refer to Channel Power Measurement on page 5-31)along with the adjacent transmit channels that have been configured in the setup menu. In this example display, the channel bandwidth and channel spacing are set to 5 MHz.
