Accelerate your LTE Signal Burst Power Measurement with Agilent P-Series Power Meter


Using the industry’s latest development technology, the long term evolution (LTE) standard from the 3rd Generation Partnership Project (3GPP) is deployed all around the world. The complexity of the LTE system requires comprehensive signal and modulation analysis as well as RF power measurement. The Agilent P-Series power meter/sensor makes it possible to measure the sub-frame signal of time-division-duplex (LTE-TDD) and average burst power signal of frequency-division-duplex (LTE-FDD) with built-in LTE predefined measurement setup and statistical complementary cumulative distribution function (CCDF) measurement. This document explains how to generate LTE-TDD and LTE-FDD signals using Agilent N7624B/N7625A Signal Studio software along with Agilent ESG Vector Signal Generator. A step-by-step guide demonstrates time-gated/average burst signal measurement as well as CCDF measurement for LTE-TDD and LTE-FDD signals using Agilent P-Series power meter and sensor.

The combination of N1911A/12A P-Series power meters and N1921A/22A wideband power sensors can quickly and accurately measure peak, average, peak-to-average ratio power measurement, rise/fall time, pulse width, and complementary cumulative distribution function (CCDF) statistical data for wideband signals. The 30 MHz video bandwidth and 100 x 106 samples per second sampling rate of the P-Series power meter make it possible to capture signals with high crest factor and fast transition times which is the characteristic of LTE signals. The diode-based P-Series power sensor offers a higher frequency range of up to 40 GHz and wider dynamic range of up to 55 dB for better sensitivity to enable reliable measurements of peak and average burst power. Further simplifying measurement set up, the one-button predefined preset LTE setup of the P-Series power meter reduces the setup time required to capture the signal effectively. By following a few easy steps, you can use the P-Series power meter/sensor to obtain power versus time (PvT) measurement and statistical CCDF for LTE-TDD and LTE-FDD signals.
