In most power added efficiency (PAE) test setups, multiple instruments are used to measure RF, voltage, and current. Measurements may require the use of an RF power meter or digital oscilloscope (DSO) with diode detectors to determine the RF power, while digital multimeters are used to measure voltage and current. The Agilent Technologies 8990B peak power analyzer (PPA) provides an alternative setup which allows power added efficiency testing to be done on a single instrument.
