bk891 is a self-contained SCPI "driver" library for the BK Precision 891 LCR Meter. It provides a pythonic interface to all of the documented SCPI commands in the manual. Query results are returned as native python datatypes for easy integration into the rest of your project.

This library is based on the bkp879b library by Jim Battin.

Serial communication is handled by the pyserial library (http://pyserial.sourceforge.net/)

• Comma-separated results are contained inside a tuple
• All scientific notation values are returned as floats
• 'ON' 'OFF' values are returned as a boolean
• Integer values are returned as integers
• N or '----' values are returned as a None type
• Everything else is returned as a utf-8 string

For a detailed list of functionality see the bkp891/scpi891.py file

Installation:

pip install bkp891

Usage:

import bkp891

instrument = bkp891.connect("/dev/yourdevice") # Windows users can just pass in 'COMx'
