IEEE Transactions on Instrumentation and Measurement
Year: 2025 | Volume: 74 | Journal Article |
In this work, a method for the calibration of the magnitude and phase of lock-in amplifiers (LIAs) and the characterization of their noise response are presented. A simple calibration setup developed at INRIM is used to calibrate the magnitude and phase of digital LIAs. These quantities are typically loosely or not specified, respectively, by the manufacturers. Furthermore, since the low-pass filt...Show More
