1 Introduction
Product Overview
The E6651A Test Set is designed to test and analyze the
performance and signaling of Mobile WiMAX subscriber
stations based on the IEEE 802.16e standard. The Test Set
consists of three major operating modes:
Figure 1 The Agilent E6651A Mobile WiMAX Test Set
Base Station Emulator (BSE)
In Base Station Emulator (BSE) mode, the Test Set simulates
the operation of a Mobile WiMAX base station.
Signal Analyzer (SA)
In Signal Analyzer (SA) mode, the Test Set can be used to
analyze Mobile WiMAX uplink signals using modulation,
spectrum and flatness analysis. Modulation Analysis mode
displays the OFDM signal in both frequency and time
domain. The Spectrum Analysis functionality, implemented
using a Fast Fourier Transform (FFT) algorithm, displays the
measured WiMAX signal in the frequency domain. Flatness
Analysis enables comparison of power levels of the spectral
components.
Signal Generator (SG)
In Signal Generator (SG) mode, the Test Set generates
standard Mobile WiMAX uplink and downlink signals.
