The Lock-In Amplifier for myRIO helps you use the myRIO Student Embedded Device as a precision measurement instrument.
The Lock-In Amplifier for myRIO is a software add-on for LabVIEW that can use the myRIO-1900 Student Embedded Device to implement a lock-in amplifier in the FPGA. With this add-on, you can measure a modulated signal and a reference signal, which can also be generated with the myRIO Student Embedded Device. You also can measure low-level input signals even if they are buried in noise or are smaller than the myRIO 12-bit analog input resolution. The Lock-In Amplifier for myRIO includes a highpass filter to remove input DC offset and features a programmable output lowpass filter that removes any noise beyond the frequencies of interest.
