The Utility
Functions Group
Functions in this group do not directly control instrument operation but
come to assist in extracting important information from the 3156B such
as when was the last calibration date, what option was installed in the
factory and more.
Parameter ranges and their defaults are given where applicable. The
communication session is terminated with the close function.
