Rohde & Schwarz simplifies measurements on LTE devices

Measure radiated spurious emissions on LTE devices

Rohde and Schwarz's OSP (open switch and control platform) equipped with the OSP-B155 option can be used to measure RSE (radiated spurious emissions) on LTE devices.

Housed in two height units in its control cabinet, the system defines 43 frequency bands and can transmit - at full power - in six bandwidths in each band. The R&S OSP-B155 plug-in module shifts the entire received signal spectrum into the optimum power range to allow full use of the dynamic range of the connected EMI test receiver. The receiver can analyze the entire LTE signal spectrum without requiring a notch filter to detect all relevant spurious emissions. The R&S ESU EMI test receiver sensitivity is 155 dBm/Hz, combined with a range of 80 dB in the relevant frequency range.


The R&S OSP-B155 option, fitted into two slots on the R&S OSP, is designed for use with the R&S ESU EMI test receiver and R&S EMC32 EMC measurement software. The company states that with the R&S CMW500 wideband radio communication tester, which provides LTE signaling, the new RSE measurement solution integrates into existing applications and systems.
