Signal which prevents accidental operation by spurious signals or avoids possible ambiguity .
防止假信号的意外作用或者避免二义性而设置的信号。
Without proper shielding of the switches, interconnecting cables, and test fixturing, spurious signals (offsets) may be generated that will compromise the signal being measured.
若开关、互连电缆和测试夹具没有合适的屏蔽，所产生的杂散信号（偏移）将威胁到被测信号。
In these cases, filters can be added to the switch to modify the signal frequency bandwidth, or spurious signals at unwanted fre quencies can be eliminated from the signal to the DUT.
在这些情况下，可向开关加入滤波器来改变信号的频率带宽，或者从发射到DUT的信号中消除有害频率的杂散信号。
