- Horizontal and vertical betatron tunes and the synchrotron tune are measured frequently during storage ring commissioning. The measurements are tedious and subject to human errors. Automating this kind of repetitive measurement is underway using LabVIEW for Windows, a software application supplied by National Instruments Corporation, that provides acquisition, graphing, and analysis of data as well as instrument control through the General Purpose Interface Bus (GPIB). We have added LabVIEW access to the Advanced Light Source (ALS) data base and control system. LabVIEW is a fast and efficient tool for accelerator commissioning and beam physics studies. Hardware used to perform tune measurements include a tracking generator (or a white noise generator), strip line electrodes for external ``citation of the beam, button monitors, and a spectrum analyzer. All three tunes are displayed simultaneously on the spectrum analyzer. Our program automatically identifies three tunes by applying and analyzing small variations and reports the results. This routine can be encapsulated in other applications, for instance, in a chromaticity measurement and correction program.
