1K Data(1024 Data)
Consequently, the relationship among the number of channels, the number of samplings, and the sampling clock
that can be sampled as described in the specification of the hardware is as follows:

In the driver data software, the buffer memory is expanded to a 256 x 1024 data.
However, if the number of samplings that exceeds the table above is specified, an adjustment of the sampling clock
is required for the data transfer process from the device to the PC, which may prevent a sampling with the
sampling clock above.
