2.3.4 Applications: History Channel Functions
2.3.4.1 History Application: Function Entry
With the History Application, the
output of self defined functions or
integrals can be followed in a graph
against time. Up to 8 functions can be
followed simultaneously.
The functions are defined in the dialog
at the right, which is shown after the
History-Function Entry option has been
chosen.
The functions F1 to F8 can be selected
by clicking the corresponding TAB sheet
at the top of this dialog.
Furthermore, a number of general
(function independent) parameters can
be entered, below of the function TAB
sheets.
Function Type
The first time that the Function Entry dialog is activated, all 8 functions are not activated (Function
Type = None). To define a function, the Function Type radio button needs to be changed from None
to: Integral, User Defined or View Spectrum. After defining the function type, the Function
Definition and Function Display Settings can be set.
Function Definition
The parameters that need to be entered in the Function Definition Box depend on the Function
Type that has been chosen: Integral, User Defined or View Spectrum.
Function Definition-Integral
In case a function is defined to display the integral versus time, the following parameters can be
set:
Spectrometer Channel. The default is Master, but in case more channels are available, this can be
changed to Slave1, Slave2…..up to Slave7.
The “from” and “to” edit boxes may be changed to specify the Raman Shift range in cm -1 over
which the integral needs to be calculated.
Finally, a multiplication factor can be entered. The value entered here is multiplied with the
calculated integral.
