A power search temporarily enables the ALC (closed-loop mode), adjusts the RF output power for better accuracy, and then disables the ALC (open-loop mode). Performing a power search is useful during modulation, specifically when you desire the accuracy of the ALC closed-loop mode but cannot enable ALC because doing so interferes with the modulated signal.
Power search is supported only when using the PXIe-5654 RF Analog Signal Generator with the PXIe-5696 Amplitude Extender.
Perform a power search by completing either of the following options:
