在低阻电路上往往会出现毫伏级的杂散信号，大多数是由于热电效应引起的。

Spurious microvolt level signals are often present in low resistance circuits, most often as a result of thermoelectric effects.

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。

Without proper shielding of the switches, interconnecting cables, and test fixturing, spurious signals (offsets) may be generated that will compromise the signal being measured.

white space是行业术语，指的是毗连电视频段的未使用的波段，它还可以为收到的杂散信号和其他干扰提供缓冲。

White space is industry lingo for the unused airwaves that abut TV spectrum and provide a buffer from stray signals and other interference.
