Application Note: Adjacent Channel Power Ratio (ACPR)

Adjacent channel power ratio (ACPR) is an increasingly critical measurement, particularly for power amplifier and amplifier subassembly manufacturers. This measurement is often time consuming, may require specialized equipment and has a significant potential for error. To have such a measurement incorporated into an integrated test system can radically reduce test time and expense. This note will explore such a system based on the Scorpion® family of instruments including the ACPR measurement options available, uncertainty issues, and some setup requirements.
