| - | Python IVI can use Python VXI-11, pySerial and linux-gpib to connect to instruments. The implementation of the initialize method takes a VISA resource string and attempts to connect to an instrument. If the resource string starts with TCPIP, then Python IVI will attempt to use Python VXI-11. If it starts with GPIB, it will attempt to use linux-gpib's python interface. If it starts with ASRL, it attemps to use pySerial. Integration with PyVISA is planned, but not currently supported. | + | Python IVI can use Python VXI-11, Python USBTMC, pySerial and linux-gpib to connect to instruments.
