Problem:
What are the available IEPE excitation levels for National Instruments Dynamic Signal Analyzer (DSA) devices?

Solution:
Different DSA devices provide different values for excitation. In software these values can be set to a range of values but are eventually coerced to allowable values in hardware.

Here is a table of current excitation values for the NI-443x, NI-446x, NI-447x, NI-4496/4498 and NI-923x DSA devices:

Note: The PXI-4495 does not support IEPE excitation.

Module	Valid SW Values	Actual HW Values
443x	0mA	0mA
	2mA to 2.1mA	2.1mA
	Other	Error
446x	0mA	0mA
	2mA to 10mA	4mA
	10mA to 20mA	10mA
	Other	Error
447x	0mA	0mA
	2mA to 20mA	4mA
	Other	Error
4496/8	0mA	0mA
	2mA to 20mA	4mA
	Other	Error
9233	2mA to 20mA	2mA
	Other	Error
9234	0mA	0mA
	2mA to 20mA	2mA
	Other	Error

If a value is entered in the 'Other' category, an error will occur.

Please refer to each device's specifications link below for more detailed information on their IEPE excitation. Depending on the sensor's excitation requirements, this could dictate which product is best for the application.
