i need to run MTS (fatigue testing) 407 controller with external control using labview - The 407 contoller uses BNC connections for program source input. In addition, has anyone written a VI code for sinusoidal loading with rest period to control the 407?I am not familiar with the MTS instrument. GPIB devices have an IEEE standard 24pin connector so I believe your device is not a GPIB device based on your description of it (BNC connectors). I might recommend contacting the vendor of the instrument for specific information on how to interface the device to your PC.
From a LabVIEW point of view, what ever interface is installed, LabVIEW can make direct calls to any DLL shipped with the device by using a Call Library Function. Documentation on the functions would have to provided to you by the vendor of the interface.
