PyVISA allows dialog between a computer and various engineering instruments such as oscilloscopes, spectrum analyzers, waveform generators, etc. using the VISA Framework of National Instruments, which must be installed independently. {
WARNING:} VISA Frameworks prior to 14.0, (released 2014), are 32-bit only, so to be able to use py-visa on a 64-bit machine, you MUST {
EITHER} {
	install} a 64-bit-compatible VISA version {
OR} {
	install} a universal Python and execute python in 32-bit mode with ‘arch -i386’.
