Chapter 6: Testing Your Module 67
Verifying With Test
Instrumentation
The 1746sc-NI8u has multiplexed channel inputs which switch in order to
read an input channel. The settling time is 3ms. Caution must be used
when testing the module with a test instrument, because the instrument
may require a settling time much greater than 3 ms. Errors will result in
the test instrument sourcing if its settling time requirement is not met.
Contact the instrumentation manufacturer for settling time requirements
before using the instrument to test your module.
