Lesson 4: Basic scan (& plot) of scaler vs. motor#
Preparation
``instrument`` package
Make sure the instrument package is in the same directory as this jupyter notebook. The instrument package included with this lesson is a brief version of the standard package used with any APS instrument. Since the notebook is for teaching, it does not connect with any mongodb database. The scans are not kept by the databroker. However, every scan is saved to a SPEC data file as described when the instrument package is loaded.
