The R&S CMW270 WiMAX tester ensures maximum throughput in the production of WiMAX chipsets and mobile stations. It combines signal generation and signal analysis in a single box. Three calibrated RF connectors in the RF front end reduce test setup complexity. It generates continuous wave (CW) and orthogonal frequency division multiple access (OFDMA) signals in line with the WiMAX IEEE 802.16e standard for frequency and level calibration. It measures RF power, error-vector magnitude (EVM), adjacent-channel power (ACP), and spectrum flatness; it also includes spectrum mask and I/Q constellation functions.
The tester's nonsignaling mode makes it possible to calibrate the transmitters and receivers of WiMAX mobile stations and to measure the received signal characteristics. A forthcoming signaling mode will support base-station emulation.
