niHSDIO_ConfigureDataPositionDelay
Specific Function
C Function Prototype
ViStatus niHSDIO_ConfigureDataPositionDelay (ViSession vi, ViConstString channelList, ViReal64 delay);
Purpose
Sets up the data delay with respect to the Sample clock. To configure the data delay, select NIHSDIO_VAL_DELAY_FROM_SAMPLE_CLOCK_RISING_EDGE as the value for the position parameter of the niHSDIO_ConfigureDataPosition function.
 |
Note To configure a delay on NI 656x devices, you must delay all channels on the device. NI-HSDIO returns an error if you apply a delay to only a partial channel list. |
Parameters
| Name | Type | Description |
|---|---|---|
| vi | ViSession | This handle identifies your instrument session. vi was obtained from the niHSDIO_InitAcquisitionSession or niHSDIO_InitGenerationSession function. |
| channelList | ViConstString | Identifies channels to apply settings. Use "" or VI_NULL
to specify all channels. Default Value: "" |
| delay | ViReal64 | Specifies the delay after the Sample clock rising edge when the
device generates or acquires a new data sample. Data delay is expressed as a fraction of the
clock period, that is, a fraction of 1/NIHSDIO_ATTR_SAMPLE_CLOCK_RATE.
All the channels in the session that use delayed Sample clock to position data must have the same
delay value. Default Value: 0.00 |
