VEE Programming Examples
About This Chapter
The focus of this chapter is to demonstrate a multitude of VEE programming
examples to help get the VT1419A application running as quickly as possible.
Several VEE programs exist, but, to simplify the discussion, Agilent VEE examples
are provided. These examples are a combination of fully working programs that
demonstrate various capabilities of the VT1419A plus Agilent VEE object modules
that can be merged into Agilent VEE applications to perform such operations as
calibration, error checking, testing, custom functions and custom EU conversion.
Any operation or function that may seem hard to implement with the VT1419A has
been included in the spirit of Agilent VEE objects. Simply merge the examples and
cut and paste what is needed. This typically results in complex functions being
performed in a very short period of time.
These example programs are written to run on any Agilent VEE 3.0+ platform. This
includes UNIX and Microsoft
®
Windows
®
98, Windows NT
®
4.0, Windows 2000, or
Windows XP operating systems. These programs are primarily designed to run
from an external computer communicating over a GPIB link to the
Agilent/HP E1405B/06A Command Module. The Command Module holds the
VT1419A driver which controls the VT1419A VXI card. The VT1419A VXI card
comes pre-configured to LADD 208 (GPIB address 70926, for example).
These Agilent VEE programs are also viable for the VT1415A Algorithmic Closed
Loop Control card since the programming architecture of both cards is very similar.
The VT1415A provides greater flexibility and focuses more closely on PID closed
loop control applications. The VT1419A is a more general purpose/lower cost data
acquisition and control system solution.
NOTE The programming examples that follow reference model numbers which have an
"E" prefix (e.g. "E1419A"). After the acquisition of these products by
VXI Technology, Inc., the prefix has been changed to "VT" (e.g. "VT1419A").
These prefixes are interchangeable and vary with firmware revision and date of
product purchase.
