lte beamforming measurements 1ma187 multiple input multiple output (mimo) technology is an integral part of 3gpp e-utra long term evolution (lte). as part of mimo, beamforming is also used in lte. this application note provides a brief summary of the transmission modes (tm) in lte and describes the beamforming measurements for base stations (bs) and user equipment (ue). the t&m options using various
使用慢速 i/q 信号测试基于 fpga 的硬件模拟器 carolin tröster-schmid 1gp95 在芯片组或模块的设计过程中,可以使用基于 fpga 的硬件模拟器对实际测试与测量仪器进行早期测试。 这些硬件模拟器通常以模拟减慢的速度运行,但除此之外,所有功能都与最终设计一样。 在此应用指南中,我们解释了如何使用罗德与施瓦茨矢量信号发生器在降低的采样率下创建合适的实时测试信号,以便测试基于 fpga 的硬件模拟器。 我们还进一步解释了如何针对“慢速 i/q”正确调整 awgn 信号生成以及衰落模拟。 fpga, 硬件模拟器, awgn, 信号生成, 衰落模拟, 测试, 测试, 慢速 i/q, palladium, 采样率 在此应用指南中,我们解释了如何使用罗德与施瓦茨矢量信号发生器在降低的采样率下创建合适的实时测试信号,以便测试基于 fpga 的硬件模拟器。 我们还进一步解释了如何针对
starting successfully with the r&s®ex-iq-box 1ma168 the r&s ex-iq-box serves as a digital baseband interface between a device under test (dut) and rohde & schwarz generators, analyzers and radio communication testers. the digiconf software supplied with the device controls up to four r&s ex-iq-boxes in a test setup and can thus output iq data for feeding into a dut while simultaneously receiving iq
r&s®cmw500 digital iq with cadence emulator 1cm75 this application note explains how to bring a cadence system which is attached to an r&s ex-iq-box into service for the first time. the first part of the document shows how to setup an lte demo without using a ue design. this setup uses the r&s cmw500 as the downlink transmitter. the emulator receives the downlink via an r&s ex-iqbox and passes it to
