Parameters
- enable
- Type: System.Boolean
Enables support. true (True in Visual Basic) if you wish to enable support; otherwise false (False in Visual Basic).
- rate
- Type: System.Double
The sample rate, in hertz (Hz). If you set this parameter to a value of -1, the method configures the device to use its maximum rate.
Remarks
Specifies to read from AI channels at the Sample rate that you specify. This option is useful for certain NI-DAQ SC Express devices that acquire data at a much slower rate than the other DAQ devices in the system. It allows a slower device, such as a thermocouple device, to run at its own sampling rate instead of the rate determined by the chassis master hardware synchronization device for the system.
 Note: |
|---|
This option is disabled if at least one of the following conditions is true: |
- Hardware-timed single-pont sampling is disabled for the AI channels.
- This device is set to be the chassis master synchronization device.
