Simple Test Application (U2300 Auto Prog Tool.vee)
U2300A Quick Reference Guide
This application allows the user to test three devices via the
analog input of the U2300A Series DAQ devices. The
program also allows the user to control a SCPI- based power
supply. The DAQ can either be on a USB port or in a
cardcage. However, the present program can only support
one DAQ at a time. Digital outputs from the U2300A are
used to supposedly switch the DUTs. All the test results will
be displayed and also the user can determine the sequence
of the test, settings on the power supply and also the test
limits.
The analog input channels used are channel 101, 102 and
103. Polarity of these channels are fixed as bipolar and 10 V
ranges which is the default settings. It can support any
U2300A models. The digital output channel used is channel
501 with only three bits being utilized, mainly Bit 0,1 and 2
for each DUT. The application uses the userfunctions
imported from "Simple U2300_AI.vee" and "Simple
U2300_DIO.vee". It does not use "U2300_AI.vee" and
"U2300_DIO.vee" as these programs have complex variable
constant that have the same declaration.
The application start by importing in the userfunctions from
the two VEE files. The object is located in "Main" workspace
called "Import Libraries".
Once the userfunctions are imported, it does an
auto- detection for any instrument that is connected to the
computer. The function "InstrAutoDetect ()" will display the
identification and the address of the detected instrument
and prompt the user to select it.
