SOLUTION BROCHURE RF Power Amplifier Test, Reference Solution Challenge the Boundaries of Test Agilent Modular Products The RF power amplifier test, reference solution provides a unique combination of test speed and throughput with trusted and consistent measurements for cellular and wireless connectivity formats. RF power amplifier (PA) test challenges Wireless mobile device manufacturers continue to face pressures to simultaneously reduce cost and increase data throughput without sacrificing battery life. These requirements create conflicting challenges for test engineers because they must reduce overall test system cost and test times despite adding complex test techniques such as envelope tracking (ET). These techniques are required to optimize RF PA power efficiency which add to test system cost. Testing RF PAs with ET brings new challenges: • Test environment must include additional envelope generation capabilities to test under realistic conditions • Tight alignment between signal and envelope has a significant effect on the quality of measurement • Precision power sourcing and measurements are required during test since power consumption is a critical factor RF power amplifier test, Reference Solution The RF PA test, Reference Solution is a combination of hardware, software, and measurement expertise providing the essential components of a PA test system. This enables engineers to use, enhance, or modify the test system as required to meet specific test application needs including envelope tracking and RF Front End (RFFE) control. Control software enables tight synchronization between the signal source and the arbitrary waveform generator (AWG), resulting in optimal alignment between input signal and envelope. A stepped FFT technique provides high speed, wide dynamic range harmonics measurements up to 27 GHz. Precision power sourcing and measurement is also included in this solution. To facilitate evaluation and integration in your test environment, you can use supplied test code examples that have been designed to optimize test throughput without compromising performance.
