The objective of the simulation software is to help answer questions about how well a lock-in amplifier can recover a signal from noise (the 'accuracy' of the result provided by the instrument) and about the possible dispersion of values obtained (the 'precision' of the result). The software allows users to investigate the performance and limitations of ideal and imperfect instruments applied to simulated and real test signals.
The software was developed using LabVIEW version 8.5 and compiled into a standalone Windows executable.
Two versions of the software are provided:
- One for users who already have LabVIEW or the LabVIEW 8.5 Run-Time Engine installed on their PC. This version is contained within the ZIP file lia_r1_excrte.zip.
- A second version, lia_r1_incrte.zip, is for users who do not have a LabVIEW Run-Time Engine currently installed on their PC.
After you have downloaded and unzipped the file appropriate to your PC, follow the installation instructions to be found in the text file readme.txt.
