Touchstone 2 Pdf Free Download

Since the early 16th century, touchstone has referred to a particular kind of siliceous stone (that is, stone containing silica) used to do a particular job: determine the purity of precious metals. The process involves comparing marks made by rubbing a sample of a metal of known purity to marks made by a metal of unknown purity. The method is accurate enough in the case of determining the purity of gold that it is still in use today. Figurative use extended from this literal use, with touchstone functioning as a word for a test or criterion to determine the quality of a thing, and later to refer to a fundamental or quintessential part or feature of something.
Can someone please suggest an example VI for reading a touchstone data file (A__S_params.s2p) for me as a starting point. I want to get the magnitude and phase data of S21 to design a filter. I have tried to use Touchstone Data Plugin with the (DataPlugins - ATML) project from the LabVIEW example finder to first convert Touchstone file to TDMS format but have not been successful. Thanks.
Actually I've seen different flavors depending on the originator of the file. The Touchstone File Specification data line formatting rule just says that individual entries are separated by whitespace. HP-ADS separates the values with multiple space characters, the N5230A and C uses a single space character, the E5071C uses a single tab character. I usually replace multiple spaces or tabs with a single tab before processing the data.
I have just placed both the folders in the user.lib folder and have restarted LabVIEW. I can see both the palettes now with all the functions and controls. That should help solve my problem. Thanks to all of you.
