4 Analyzing and Displaying Test Data Chapter
Figure 116 Evaluating an Expression
Using an Agilent VEE Function in the Formula Object
This example generates a cosine wave and calculates the
standard deviation and root mean square using the Formula
object.
1 Select the Function Generator, Formula, and AlphaNumeric
objects and connect them together using their data pins.
2 Clone the Formula object by opening the object menu and
selecting Clone, and place it just below the first one. Connect
the Function Generator data output pin to the second
Formula object.
3 Clone another AlphaNumeric display and connect it to the
second Formula object.
4 Enter sdev(A) in the first Formula object, and rms(A) in the
second Formula object.
sdev(A) and rms (A) are the two math functions from the
Device
Function & Object Browser dialog box. Notice that they
can be called as functions or independent objects, and they
will perform in the same way.
5 Run the program. The program displays the same answers
when these functions are put into the Formula object as it
did when they were used as independent objects, as
shown in
Figure 117.
