virtual instruments (skrf.vi
)
This module defines “virtual instruments” or interfaces to a number of different types of instruments used in RF measurements and experiments.
Creating A Driver
Drivers are classes inherited from the respective instrument type’s abstract base class and define methods specific to each instrument. This syntax can be complex and vary wildly between devices and manufacturers. The vi module attempts to present a standard interface for each.
Basically, creating a driver consists of the following:
Creating an instrument class that inherits from its abstract base class
Consulting the device’s datasheet to find the command for each method in the abstract base class
Those wishing to use an instrument that’s not supported are encouraged to consult existing classes to understand the architecture, develop their own class, and contribute it to scikit-rf.
If you choose to do so, please try to use the following standard terms for the associated meaning
