Parameters
| Input | ||||||
| Name | Type | Description | ||||
| vi | ViSession | Identifies a particular instrument session. vi is obtained from the niDCPower_InitializeWithIndependentChannels function. | ||||
| channelName | ViConstString | Specifies the channel(s) to use. Specify the channel(s) using the form PXI1Slot3/0,PXI1Slot3/2-3,PXI1Slot4/2-3 or PXI1Slot3/0,PXI1Slot3/2:3,PXI1Slot4/2:3, where PXI1Slot3 and PXI1Slot4 are instrument resource names and 0, 2, and 3 are channels.
If you pass "" for this control, all channels in the session are used. |
||||
| inputTerminal | ViConstString | Specifies the input terminal for the digital edge Source trigger.
You can specify any valid input terminal for this function. Valid terminals are listed in MAX under the Device Routes tab. For the PXIe-4147 and PXIe-4162/4163, refer to the Signal Routing topic for the device to determine which routes are available. This information is not available on a Device Routes tab in MAX. Specify the input terminal using the form /Dev1/PXI_Trig0, where Dev1 is the instrument and PXI_Trig0 is the terminal. The input terminal can also be a terminal from another instrument or channel. For example, you can set the input terminal on Dev1 to be /Dev2/Engine0/SourceCompleteEvent, where Engine0 is channel 0. |
