摘要: Transmitters employed in modern wireless communication systems generally incur power and carrier transients. With the aim of limiting possible interference to other equipment operating adjacent channels, European standard on electromagnetic compatibility radio spectrum matters imposes upper bounds transmitter attack time. The also recommends a suitable test setup, which great number instruments are involved. authors propose an alternative digital-signal processing method for time measurements, based time-frequency representations. simultaneously measures both frequency transients, requires only data acquisition system unit. Moreover, thanks use band-pass sampling strategies already proposed by authors, just few thousand samples have be acquired measure Optimal TFR parameter combinations singled out through experimental tests emulated signals, examples application actual RF transmitters provided
