Connection

VISA Instrument Communication

• All instruments drivers inherit from yaVISA.py
• yaVISA.py
  • default VISA connection.
  • Requires installation of VISA driver on local machine
  • Typical use:
    • HiSlip: instrument.jav_Open('192.168.1.10')
    • Direct: instrument.jav_openvisa('TCPIP0::192.168.1.10::hislip0')

Socket Instrument Communication

• yaVISA_socket.py
  • Replaces VISA open, write, & query methods with socket equivalent.
• To use:
  • Delete/rename jaVISA.py
  • Rename jaVISA_socket.py to jaVISA.py
  • Code will now make socket connections alone.

Socket port

• Default instrument.jav_Open('192.168.1.10') opens w/ port 5025
• Specify port w/ instrument.jav_Open('192.168.1.10',port=100)
