SELECTIVITY TEST |
摘要 |
Testing radio equipment is described wherein an interfering signal is swept in frequency with a step size that is chosen proportional to the bandwidth of the receive channel of the radio equipment. For example, a respective frequency bandwidth (BCh) is determined of a plurality of receive channels of the radio equipment. A proportionality constant is selected for a frequency step size. For each respective receive channel, interfering radio signals are generated and the interfering radio signals are controlled to stepwise sweep in frequency outside of each respective receive channel. The stepwise sweeping of the interfering frequency is performed with a frequency step size that is a product of the respective bandwidth and the selected proportionality constant. Any spurious response is detected in the respective receive channel. |
