Voltage Channel Properties (AI)

Last Modified: June 10, 2021

Configure analog input (AI) channel properties to measure voltage.

For more information on measuring voltage, refer to the NI-DAQmx Manual.

Property/Section Description
Minimum Value The minimum value you expect to measure before VeriStand performs any scaling or calibration.
Maximum Value The maximum value you expect to measure before VeriStand performs any scaling or calibration.
Input Configuration
Specifies the input terminal configuration to apply to the device channels.

Note  

If you select any configuration other than Same as device, it overrides the configuration you specify for the device on the DAQ Device Configuration page in System Explorer.

  • Same as device—The same configuration specified for the DAQ device itself. To set the input terminal configuration at the device level, use the Input Configuration pull-down menu on the DAQ Device Configuration page.
  • Default—At run time, NI-DAQmx chooses the default terminal configuration for the channel.
  • RSE—Referenced single-ended mode.
  • NRSE—Non-referenced single-ended mode.
  • Differential—Differential mode.
  • Pseudodifferential—Pseudodifferential mode.
Filter Type (supported devices only) Specifies whether to apply a digital filter to the input signal:
  • Disabled—No filter.
  • Lowpass—Eliminates all signal frequency components above the cutoff frequency.
Filter Cutoff Frequency (supported devices only) Specifies the cutoff frequency of the digital filter.
In-Situ Calibration (supported devices only) Specifies whether to perform an in-situ calibration and when to perform the calibration:
  • Before deployment—Perform an in-situ calibration before the system definition is deployed.
  • After undeployment—Perform an in-situ calibration after the system definition is no longer deployed.
  • Both—Perform an in-situ calibration before the system definition is deployed and after the system definition is no longer deployed.
  • None—Do not perform an in-situ calibration.
In-Situ Minimum Value (supported devices only) The minimum value you expect to measure when VeriStand performs an in-situ calibration.
In-Situ Maximum Value (supported devices only) The maximum value you expect to measure when VeriStand performs an in-situ calibration.
In-Situ Input Configuration (supported devices only) Specifies the input terminal configuration to use when performing the in-situ calibration:
  • Same as device—The same configuration specified for the DAQ device itself. To set the input terminal configuration at the device level, use the Input Configuration pull-down menu on the DAQ Device Configuration page.
  • Default—At run time, NI-DAQmx chooses the default terminal configuration for the channel.
  • RSE—Referenced single-ended mode.
  • NRSE—Non-referenced single-ended mode.
  • Differential—Differential mode.
  • Pseudodifferential—Pseudodifferential mode.
Lowpass Cutoff Filter Frequency (supported devices only) Specifies the frequency that corresponds to the -3dB cutoff of the analog filter.
