Description
Specifies whether you want the device to acquire or generate in single data rate (SDR) mode or in double data rate (DDR) mode.
Defined Values:
| NIHSDIO_VAL_SINGLE_DATA_RATE (1) | The device samples or generates data in single data rate (SDR) mode. When in SDR mode, the NI digital waveform generator/analyzer generates or acquires data on a single edge of the Sample clock. Therefore, you can generate or acquire data on the rising or falling edge of every Sample clock pulse or on a delayed version of the rising edge of the Sample clock. |
| NIHSDIO_VAL_DOUBLE_DATA_RATE (2) | The device samples or generates data in double data rate (DDR) mode. When in DDR mode, the NI digital waveform generator/analyzer generates or acquires data on both edges of the Sample clock. Therefore, you can generate or acquire data on every rising and falling edge of the Sample clock. Acquisition and generation sessions can be configured in DDR mode to acquire or generate the first data sample on the rising or falling edge of the clock or on a delayed version of the rising edge of the clock. |
