#2)Build timing information. For this purpose we use a MDSplus "Dimension" object which contains two fields:
# "Window" and "Axis". Window object defines the start and end index of the associated data array and the time which is
# associated with the sample at index 0. Several possible combination of start and end indexes are possible (the can also be
#negative numbers). We adopt here the following convention: consider index 0 as the index of the sample corresponding
#to the trigger, and therefore associated with the trigger time. From the way we have built the reduced raw sample array,
#it turns out that the start idx and end idx defined
#in the Window object are the same of the start and end indexes defined in the device configuration.
#
#The "Range" object describes a (possibly multispeed or busrt) clock. Its fields specify the clock period, the start and end time
#for that clock frequency. In our case we need to describe a continuous single speed clock, so there is no need to
#specify start and end times(it is a continuous, single speed clock).

#build the Dimension object in a single call

#3) Put all togenther in a "Signal" object. MDSplus Signal objects define three fields: samples, raw samples, dimension
# raw samples are contained in reducedRawChan. The computation required to convert the raw 16 bit sample into a +-10V
# value is: sample = 10.*rawSample/32768. We may compute a new float array containing such data and store it together
# with the raw sample (in the case we would like to reain also raw data. There is however a better way to do it
# by storing only the required information, i.e. the raw(16 bit) samples and the definition of the expression which
# converts raw data into actual voltage levels. Therefore, the first field of the Signal object will contain only the
# definition of an expression, which refers to the raw samples (the second field) of the same Signal object.
# The MDSplus syntax for this conversion is: 10.*$VALUE/32768.
# We shall use Data method compile() to build the MDSplus internal representation of this expression, and the stick it
