KPCI-3110 and KPCI-3116 User’s Manual
Systematic Problem Isolation
C-15
Specified hardware I/O tests
The tests in this section check whether the analog and digital I/O of the board work properly.
The I/O are tested using proven DriverLINX utilities, thereby bypassing any unresolved applica-
tion software issues. These tests are intended to be used when specified in the preceding proce-
dure. However, they may also be used at any time for general functional checks of your
KPCI-3110 or KPCI-3116 board.
NOTE
During these tests, disconnect all user circuits from board, except for
connections specified in individual test procedures.
Analog input hardware test
The analog input test checks whether the analog inputs, particularly the instrumentation
amplifier and A/D converter, are working correctly. In this test, a voltage applied to KPCI-3110
or KPCI-3116 channel 01 is measured using the on-screen digital voltmeter utility that is
supplied with DriverLINX. In the same way, channel 00 is grounded and checked for offset
voltage. One voltage measurement and one grounded-input measurement are sufficient because
of the following:
•
All analog channels are connected to the same instrumentation amplifier and A/D converter,
via the multiplexer.
•
The multiplexer is unlikely to be a problem source.
Both the voltage and grounded-input measurements are made in the single-ended input mode.
NOTE
During this test, ensure that no user circuits are connected to the
KPCI-3110 or KPCI-3116 board, except for analog input connections
specified for the test.
The analog input test is a functional test, not a calibration check,
although readings from a properly calibrated board should correspond
to a known test voltage within the accuracy specifications of the board.
If you wish to check and adjust the accuracy, refer to
