SMGU的R＆S和R＆S SMHU是应用软件而大多数信号发生器不能处理的理想选择。除了外的通道测量，比如它们能够确定无线电话设备杂散抑制高达4 GHz下所规定的化学强化处理。

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.
