What do the tests tell me?
Resource Tests. The resource tests are intended to test system capability for the current device
configuration. Resource tests are pass/fail. Test failure may indicate a lack of availability of the resource,
or a possible resource conflict.
Base Address Test. This resource test checks the base address for the selected port. Failure of this test may
indicate that the port is not properly configured within the system. See relevant operating system and
computer manufacturer’s documentation to correct the problem.
Interrupt Level Test – Tests the ability of the port to generate interrupts. Failure of this test may
indicate that the port may be currently unable to generate the necessary hardware interrupt. Should this test
fail, refer to your specific operating system and computer documentation for corrective actions.
With the presence of “Passed” messages you can exit the test program and run your application.
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 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 port. Results are given
in samples/second, where a sample (2 bytes in length)
represents a single A/D value.
