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 Rohde & Schwarz instruments are also presented.

Speed considerations for Spurious Level Measurements with Spectrum Analyzers

The measurement speed for spurious signal measurements is mainly defined by the spectrum analyzer sweep speed. With traditional swept spectrum analyzers and tight spurious limits the measurement can easily take hours or even a full day. This application note describes the differences in sweep speed between swept spectrum analyzers and modern spectrum analyzers with a wide-band FFT process, and how this improves the measurement speed for general spurious measurement.

HSPA+ Technology Introduction - White Paper

High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) optimize UMTS for packet data services in downlink and uplink, respectively. Together, they are referred to as High Speed Packet Access (HSPA). Within 3GPP Release 7, 8, 9 and 10, further improvements to HSPA have been specified in the context of HSPA+ or HSPA evolution. This White Paper introduces key features of HSPA+ and outlines the changes to the radio interface.

Bluetooth Low Energy Measurements Using R&SCBTgo; Additional Tests

Nearly all tests in accordance with the Bluetooth low energy test specification V4.0 [1] can be performed using the R&S®CBT alone. Some tests additionally call for signal generators to provide interference signals. This application note describes the tests performed with additional equipment and presents straightforward solutions based on the R&S®CBT go software.
