 This command consists of two parts: the command string
([:TRACe[<n>]]:DATA:DAC16 volatile,<flag>,) and the binary data
(<binary_block_data>).
 <flag> denotes the data transmission status and can only be set to END which
denotes the data transmission finishes.
 <binary_block_data> denotes the binary data to be downloaded. The data length
ranges from 4Bytes (2pt) to 32kBytes (16kpts). <binary_block_data> is a binary
data block starts with #. For example, #516384 binary data; the number 5
behind # denotes that the data length information (16384) occupies 5 characters.
16384 denotes the number of bytes of the binary data. As each waveform point
corresponds to two bytes of binary number (the range is from 0000 to 3FFF; 0000
and 3FFF correspond to the minimum and maximum values of the waveform
amplitude respectively), the number of bytes must be an even number.
 When END (data transmission complete indicator) is recieved, the instrument
switches to arbitrary waveform output automatically.
