Using the PyVisa library in conjunction with NumPy, SciPy, MatPlotLib, and OpenPyXl offers a very powerful tool for gathering and processing data obtained from programmable test equipment. In particular, I want to programmatically route a trigger from bus 1 to bus 2 on the backplane. To view what can be done with a PXI card with NI-VISA, select something similar to "PXI2::6::INSTR" that shows up under PXI System and press "Open VISA Test Panel".PyVISA-sim is a different back-end that basically simulates The users manual gives plenty of examples.

The example demonstrates how to open a VISA session, map a portion of memory, peek and poke registers on the device, and close the VISA session both in LabVIEW and LabWindows/CVI. I wasent able to find any working example for pyvisa using a pxi device. PyVISA is a Python "wrapper" that offers easy access to shared DLLs built into the Virtual Instrument Software Architecture specification laid down in the 1990s. It is used to control measurement devices and test equipment via GPIB, RS232, and USB Easy_install also gets 1. Pyvisa pxi example About Gui Control Instrument Python PyVISA Documentation, Release 1.
