| Name | Description |
|---|---|
| AI.MeasTypes | Indicates the measurement types supported by the channel. |
| AI.TermCfgs | Indicates the list of terminal configurations supported by the channel. |
| AI.InputSrcs | Indicates the list of input sources supported by the channel. Channels may support using the signal from the I/O connector or one of several calibration signals. |
| AI.SensorPower.Types | Indicates the types of power supplied to the sensor supported by this channel. |
| AI.SensorPower.VoltageRangeVals | Indicates pairs of sensor power voltage ranges supported by this channel. Each pair consists of the low value followed by the high value. |
| AI.PowerControl.Voltage | Specifies the voltage level for the sensor's power supply. |
| AI.PowerControl.Enable | Specifies whether to turn on the sensor's power supply. |
| AI.PowerControl.Type | Specifies the type of power supplied to the sensor. |
| AI.SensorPower.OpenChan | Indicates whether there is an open channel or undercurrent condition on the channel. |
| AI.SensorPower.Overcurrent | Indicates whether there is an overcurrent condition on the channel. |
| AO.OutputTypes | Indicates the output types supported by the channel. |
| AO.PowerUpOutputTypes | Indicates the power up output types supported by the channel. |
| AO.TermCfgs | Indicates the list of terminal configurations supported by the channel. |
| AO.ManualControl.Enable | Specifies if you can control the physical channel externally via a manual control located on the device. You cannot simultaneously control a channel manually and with NI-DAQmx. |
| AO.ManualControl.ShortDetected | Indicates whether the physical channel is currently disabled due to a short detected on the channel. |
| AO.ManualControl.Amplitude | Indicates the current value of the front panel amplitude control for the physical channel in volts. |
| AO.ManualControl.Freq | Indicates the current value of the front panel frequency control for the physical channel in hertz. |
