XY Transfer Function

 

Description

This component is essentially a piece-wise linear look-up table, where the XY coordinate points can be specified. It can be used in a variety of ways including specifying device characteristics, as a transfer function, as a signal generator, etc.

Select Yes or No. If Yes, the X input is normally time

 

 

 

 

 

Data Entry Method

 

Choice

 

Select File or Table

 

 

 

 

 

Input Type

 

Choice

 

Select REAL or INTEGER type

 

Data - TableData - Table

NOTE: These parameters are enabled only if Data Entry Method | Table is selected.

 

Number of points

 

Choice

 

Select the number of data points

 

 

 

 

 

X# / Y#

 

REAL

Constant

Enter the X and Y transfer function coordinates.  

NOTE: If Output Mode | Interpolated is selected, the X data points must be entered in ascending order.

 

Data - FilenameData - Filename

NOTE: These parameters are enabled only if Data Entry Method | Filename is selected. See Input Modes for details on the input file format.

 

File Name

 

Text

 

Enter the name of the ASCII file containing the (X,Y) transfer function coordinates. This input is used with Pathname to the Datafile is Given as below

 

 

 

 

 

Pathname to the Datafile is Given as

 

Choice

 

Select Relative or Absolute Pathname. Click on Relative Pathname if you are giving the File Name relative to the current working directory. Use Absolute Pathname if you are giving the File Name as an absolute path (Ex. C:\filename)

 

 

 

 

 

Approximate Number of Pairs of Data in the File

 

INTEGER

Literal

Choose the approximate number of data points in the file. This is important for dynamically allocating memory for the component.
