Thanks for the pointer. Which Windows environment is it developed in? I tried to load it up in VS2005 C++ and it brought up the conversion utility.. Also, all the cal routines are just 1K stubs with a couple includes. Maybe I'm looking in the wrong place? (VNAR3_HOST_source, both 1.6 and 2.0) The InstrumentCal.cpp and Calibration.cpp both have 2003 dates. Oho.. I see, they're buried in the .h and .res files.. ANd, where is the Linux port? The windows one is awfully tightly coupled between UI and processing (e.g. the actual cal work is attached to click methods for form controls), and before trying to separate them out, maybe someone has already done that. (My own style is to have the click method just invoke a UI independent routine somewhere else, so the numerical heavy lifting isn't tied to the UI) I suppose there's some mailing list around which has all this. I'll have to google for it.. >The software and documentation is available at >http://www.tapr.org/software_library.php?dir=/pub/n5eg Not much software documentation there.. just hardware and software installation/use >John James Lux, P.E.
