G-2 Resource and Performance Tests 968596 Appendix G
Interrupt Level Test – Tests the ability of a parallel port to generate interrupts. Failure of this test may
indicate that the parallel port may be currently unable to generate the necessary hardware interrupt, while
other parallel port devices may work OK in this mode. Some parallel port devices (such as printers) do not
require interrupts to work properly. See relevant operating system and computer manufacturer’s
documentation to correct the problem.
Performance Tests. These types of tests are intended
to check various device functions, using the current
device configuration. Performance tests provide
quantitative results for each supported functional group.
Test results represent maximum rates the various
operations can be performed. The rates depend on the
selected parallel port protocol, and vary according to
port hardware capabilities.
The ADC FIFO Input Speed part of the test results in a
display of the maximum rate at which data can be
transferred from the tested device’s internal ADC FIFO
to computer memory through the parallel port. Results
are given in samples/second, where a sample (2 bytes in
length) represents a single A/D value.
If the device has a WBK30 card installed, a WBK30
FIFO Test can be run.
WBK30 FIFO Test. This performance test checks the
data-storing capabilities of the optional, WBK30
memory card.
Note that the figure to the right represents results from a
previous test. Initially the screen shows no test results.
When the test is completed successfully, the Daq*
Configuration Test Dialog Box indicates a passed
condition. For example, in the above figure:
WBK30 FIFO Test Æ Æ Æ Æ Passed.
“Passed” messages indicate that you can exit the test
program and run your application.

Reference Notes:
➣
If you experience difficulties, please consult the additional user documentation before calling
technical support. User documentation is included on your data acquisition CD, and is installed
automatically as a part of product support, when your software is installed. The default location is
the Programs Group. The documentation includes API information, pinouts, troubleshooting, and a
great deal of material regarding specific DBK cards and modules.
➣
Documents can be read directly from the data acquisition CD via the <View PDFs> button located
on the opening screen.
➣
Hardcopy versions of the manuals can be ordered from the factory.
