skrf.vi.vna.NanoVNAv2.__init__

NanoVNAv2.__init__(address='ASRL/dev/ttyACM0::INSTR')[source]

Initialize a network analyzer object

Parameters

  • address (str) – a visa resource string, or an ip address

  • kwargs (dict) – visa_library (str), timeout in milliseconds (int), card_number (int), interface (str)

Notes

General initialization of a skrf vna object. Defines the class methods that all subclasses should provide, and therefore defines the basic functionality, currently focused on grabbing data more than on controlling the state of the vna

Keyword Arguments

  • visa_library (str) – allows pyvisa to use different visa_library backends, including the python-based pyvisa-py. backend which can handle SOCKET and Serial (though not GPIB) connections. It should be possible to use this library without NI-VISA libraries installed if the analyzer is so configured.

  • timeout (int) – milliseconds

  • interface (str) – one of “SOCKET”, “GPIB”

  • card_number (int) – for GPIB, default is usually 0

Parameters

address (str) –
