过去在使用高带宽示波器和有源探头进行测量时,你可以选择单端探头或差分探头。一般是用单端探头测量单端信号(对地电压),用差分探头测量差分信号(正电压—负电压)。虽然也可以只买差分探头,用差分探头测量差分信号和单端信号,但出于一些实际考虑,多数人并不这样做。理由是,在安捷 In the past when using high-bandwidth oscilloscopes and active probes for measurements, you can choose single-ended probes or differential probes. Single-ended probe is usually used to measure single-ended signal (to ground voltage), with differential probe differential signal (positive voltage - negative voltage). Although you can also only buy differential probes, differential probes to measure differential signals and single-ended signals, but for some practical reasons, most people do not. The reason is that Ansett
