AioSetAiSamplingClock

Function

If the internal clock is used, sets the internal clock.
If the internal clock isn't used, it isn't necessary to set the internal clock.

Format

Ret = AioSetAiSamplingClock ( Id , AiSamplingClock )

Parameters

Id [ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the Device ID retrieved from AioInit function.

AiSamplingClock [ C, C++ : float ] [ Python : ctypes.c_float ]
Specifies the internal clock in usec.
The available range differs by the device.

Return value

Ret [ C, C++ : long ] [ Python : ctypes.c_long ]

Return values	Content
0	Normality completion
7	Execute AioResetDevice function because the device has recovered from standby mode
10001	Invalid Id was specified Use the Id retrieved from AioInit to specify the Id in this function.
10002	AIO driver can't be called At first, perform AioInit function.
11140	The value of AiSamplingClock is outside the designated range of the function AiSamplingClock should be set to a value greater than or equal to 1.
20001	This function can't be used by this device
20003	Can not use because another process is using the device When another process is using the device, all functions except for those that support multi-process can not be performed.
21140	The value of AiSamplingClock is outside the designated range of the device being used

Initial value

It differs by the device type.

Remarks

The available internal clock is changed by the number of channels that you use.
And, even if the internal clock can be set, the conversion would be stopped if the driver cannot process in time.

This function cannot be used on devices without the analog input function.
This function can be executed if the device is working.
