Data width is the size, in bytes, of a raw sample from the operation. Raw sample refers to the native format and organization of the device, which can be an 1-, 2-, or 4-byte integer.

You can increase memory depth during dynamic acquisition by reducing the number of active channels.

To do this, specify a data width smaller than the total number of available bits for your device. For example, if you acquire data on eight of the 16 channels of an PXI 656x and you specify a data width of one byte, you can store twice as many samples than if you had specified the data width as being the entire two bytes.

Data width is read-only during generation sessions.
