SMGU的R＆S和R＆S SMHU是應用軟件而大多數(shù)信號發(fā)生器不能處理的理想選擇。除了外的通道測量，比如它們能夠確定無線電話設備雜散抑制高達4 GHz下所規(guī)定的化學強化處理。

R&S SMGU and R&S SMHU are ideal for applications which the majority of signal generators cannot handle. In addition to out-of-channel measurements, they are for instance able to determine the spurious rejection of radiotelephone equipment up to 4 GHz as laid down by CEPT.
