R&S®SMATE200A Vector Signal Generator
The production solution based on the R&S® SMU200A
Digital standard EUTRA/LTE (Option R&S SMATE-K55)
Equipped with the R&S SMATE-K55 option, the R&S SMATE200A signal generator generates high-quality downlink signals for performing tests on base station components as well as on mobile phone components and receivers. Since the option runs directly on the instruments, no external software is required. The R&S SMATE-K55 option supports the OFDMA transmission method, channel bandwidths up to 20 MHz, as well as the QPSK, 16QAM, and 64QAM modulation modes, plus it offers predefined scenarios.
With LTE, the goal is to achieve data rates of up to 100 Mbit/s in the downlink and up to 50 Mbit/s in the uplink. Moreover, LTE provides significant improvements with respect to access times, data throughput, and spectral efficiency, thus ensuring, above all, the long-term competitiveness of UMTS. As with WiMAX, data transfer from the base station to the mobile phone is based on orthogonal frequency division multiple access (OFDMA). In the uplink, the single carrier frequency division multiple access (SC-FDMA) transmission method is used. The 3GPP LTE standard is specified in 3GPP Release 8 and is scheduled to be launched in 2009.
