Rohde & Schwarz GmbH has announced a solution to measure radiated spurious emissions (RSE) on LTE devices. The solution is the R&S OSP open switch and control platform equipped with the R&S OSP-B155 option that the company said makes it easier and less costly for users to measure unwanted radio frequency.

The Rohde & Schwarz solution requires only two height units in the control cabinet, said the company. 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. The crucial prerequisite for a successful measurement using this technique is high receiver sensitivity.

R&S OSP-B155

The R&S OSP-B155 plug-in module flaunts 155dBm/Hz sensitivity.

The R&S ESU EMI test receiver offers high sensitivity of typically -155dBm/Hz, combined with a high dynamic range of 80dB in the relevant frequency range, said Rohde & Schwarz.

The R&S OSP-B155 option fits into two slots on the R&S OSP. It is designed to be used with the R&S ESU test receiver and R&S EMC32 EMC measurement software from Rohde & Schwarz. In combination with the R&S CMW500 wideband radio communication tester, which provides LTE signaling, the RSE measurement solution seamlessly integrates into existing applications and systems, added the company.
