Procedure for installing executable LabVIEW programs on Macs for Tektronix data transfer: 1. set scope IP to 192.168.15.15 (under UTILITY menu -- I/O) 2. cycle scope power 3. plug in ethernet cable (crossover not needed) 4. on the computer, log in as administrator 5. System Preferences : Network : built-in ethernet config : manual set IP to 192.168.15.17 (the first 3 numbers should be the same as above, the 4th can be anything between zero and 255) 6. using a web browser such as Safari, test the connection to the scope by typing in the scope's IP number 7. install LabVIEW Run-Time (in the Extras Folder of Installer DVD) 8. install NI-VISA (in the Drivers Folder of Installer DVD) 9. copy executable files to Applications folder To create executable files: a. open a LabVIEW project b. in the Project Explorer window, right-click Build Specifications, and choose New:Application c. under "Information", fill in names for Build specification name and Target filename d. under "Source Files", add the vi of interest to the "Startup VIs" window The "Project Files" window should have access to the folder where the vi lives. (usually user.lib folder under LabVIEW) If no files appear in the "Project Files" window, right-click on "My Computer" under "Project:projectname" and Add>File... e. under "Destinations", the Destination path shows where the executable will end up f. click the Build button 10. to fix error -1074002421, "...does not meet specified format," send HEADER OFF command to the scope (Safari : scope home page : data tab : command line) HEADER? should return zero 11. send DAT:WID 2 command to the scope this uses two bytes for data transfer in CURVE? (the default is one) this gives finer resolution, not less noise.
