Modern mobile phones can support cellular and noncellular wireless communications standards at the same time. This means, however, that the subsystems must operate in very close proximity to each other within a single device (in-device coexistence). The resulting high level of reciprocal leakage can at times cause considerable interference.This application note employs preliminary theoretical analysis and demonstrates how the problems of indevice coexistence can be measured.

Measuring the spurious emissions of transmitters used in GSM, DCS 1800 and PCS 1900 networks requires highly complex test setups since con-ventional spectrum analyzers do not have the necessary dynamic range. To obtain this range, notch filters are used to suppress the useful sig-nal. The spectrum analyzers of the FSE family make it possible for the first time to verify com-pliance with stipulated limit values for spurious emissions within the transmission band and out-side the reception band without the use of notch filters. The measurement problem and its solution by means of FSE are described in the following by way of the example of a GSM base station.
