-conDuct is a virtual parameter who has to be called as an optional argument in do1D.
conDuct has a function calcG() which allows to calculate the division of two given
parameters or one parameter and a float number. See init file for more info.
Perform a 1D scan of ``param_set`` from ``start`` to ``stop`` in
``num_points`` measuring param_meas at each step. In case param_meas is
an ArrayParameter this is effectively a 2d scan.
Args:
param_set: The QCoDeS parameter to sweep over
start: Starting point of sweep
stop: End point of sweep
num_points: Number of points in sweep
delay: Delay after setting paramter before measurement is performed
*param_meas: Parameter(s) to measure at each step or functions that
will be called at each step. The function should take no arguments.
The parameters and functions are called in the order they are
supplied.
enter_actions: A list of functions taking no arguments that will be
called before the measurements start
exit_actions: A list of functions taking no arguments that will be
called after the measurements ends
do_plot: should png and pdf versions of the images be saved after the
run.
Returns:
The run_id of the DataSet created
