| Popis: | We have developed a dual-channel lock-in amplifier (LIA) with high consistency which proves better than that of two separate single-channel LIAs in this paper. This proposed LIA obtains its high consistency by the symmetric design of the analog path and the digital algorithm structure. To show the high consistency, we respectively measured two groups of two channels, where the two channels are both from one proposed LIA in one group, and each of two is from an individual LIA in another group, using sinusoidal signal and noise as inputs. After comparing the results, we could see that the output of the proposed dual-channel LIA is with high consistency. |
