Air Traffic Control (ATC) radar, military Air Traffic Surveillance (ATS) radar and meteorological radar operate in S-Band frequency range. In fact 4G communication systems such as Long Term Evolution (LTE) make also use of these frequencies. Test and measurement of their coexistence is absolutely essential as performance degradation of mobile devices and networks and even malfunction of ATC radars has been proven.This application note describes LTE and S-Band radar coexistence test and measurement. It addresses LTE user equipment, base stations and S-Band radars and presents test solutions.

PESQ measurements employ a level adaptation algorithm and are hence widely insensitive to absolute level. However, if the tests are performed via a speech codec, the driving level of the codec has an influence on the MOS result. Therefore careful alignment of the level is required. This application note provides an application program which runs on the Audio Analyzer R&S UPV or R&S UPV66 and can be used to calibrate signal levels for the PESQ measurement.

Verification of baseband data is an important step in the early development phase of LTE/LTE-A-ready products. Comparison values for baseband data (test vectors) from other sources can be very useful in order to verify the correct implementation of the standard. Option K81 for the R&S®SMx200A vector signal generator offers sample data for LTE at the bit level. The reference data enables users to test their own implementation of the specification. The LTE bit stream verification program shown here uses data generated by this option and offers a (bitwise) comparison with bit streams generated for an LTE downlink signal. Therefore it demonstrates, how easy the option R&S SMx-K81 can be integrated into the simulation and design process during the development of LTE/LTE-A handsets or base stations.

Performing precompliance measurements on power supplies requires using a line impedance stabilization network (LISN) for results that can be compared to limit values. While LISNs are standard in any precompliance lab, often no LISN is available for early R&D testing. If high accuracy is not your goal and you just need a simple tool for debugging, you can build your own LISN. Rohde & Schwarz oscilloscopes with powerful FFT analysis, are ideal for optimizing EMI filters or debugging unwanted emissions during development.
