  • Page 155: Data Reduction And Peak List

    R&S ESCI Receiver – MEAS Key Data Reduction and Peak List EMI measurements may involve much time because the time constants prescribed by the standard for the quasi-peak weighting require transients which lead to long measurement times per each value. In addition, the standards stipulate procedures for finding local EMI maxima such as shifting the absorbing clamp, variation of the test antenna height and rotating the DUT.
  • Page 156 MEAS Key - Receiver R&S ESCI For generation of subrange maxima, the whole frequency range is divided into equidistant subranges. A subrange maximum is determined for each subrange (search method SUBRANGES). Determining the level maxima irrespective of their distribution in the frequency spectrum (search mode PEAKS) is suitable for measurement regulations that demand determination of the relatively highest level irrespective of the distribution in the measured frequency range, e.g.
