Configures coupling and integrated electronic piezoelectric (IEPE) excitation for input channels on a DSA device.

swept sine task in specifies the swept-sine parameters.
Note  Do not modify the swept sine task in values.
DSA stimulus channel settings specifies the input coupling and integrated electronic piezoelectric (IEPE) excitation on AI stimulus channel. The settings are only applied if the measurement is performed with a DSA device.
coupling specifies the coupling setting of the selected channel. The default is AC.

0AC
1DC
2GND
enable IEPE excitation specifies whether the onboard current excitation is enabled to power integrated electronic piezoelectric (IEPE) sensors. The default is FALSE, meaning that the onboard excitation is disabled.
IEPE current [mA] specifies the current value in mA for the onboard integrated electronic piezoelectric (IEPE) current excitation. The default is 4.0 mA.
DSA response channel settings specifies the input coupling and integrated electronic piezoelectric (IEPE) on AI response channel. These settings are only applied if the measurement is performed with a DSA device.
coupling specifies the coupling setting of the selected channel. The default is AC.

0AC
1DC
2GND
enable IEPE excitation specifies whether the onboard current excitation is enabled to power integrated electronic piezoelectric (IEPE) sensors. The default is FALSE, meaning that the onboard excitation is disabled.
IEPE current [mA] specifies the current value in mA for the onboard integrated electronic piezoelectric (IEPE) current excitation. The default is 4.0 mA.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
time to settle [s] specifies the amount of time to wait, in seconds, to allow the measurement hardware to settle. Specify a value for this parameter if you change input coupling or integrated electronic piezoelectric (IEPE) excitation. The default is 0.0 s.
swept sine task out returns the swept-sine parameters.
error out contains error information. This output provides standard error out functionality.
