Example:
An 8 point sine wave down loaded into wave 2, address 48.
WVFM:WAVE 2;MEM 48,#40016 binary_data \n
Where binary_data are the following values as bytes sent to the GPIB or
RS-232.
|128| 0|218|129|255|255|218|129|128| 0|37|126| 0| 0| 37|126|
The complete command as bytes in memory would look like the following:
|'W'|'V'|'F'|'M'|':'|'W'|'A'|'V'|'E'|' '|'2'|';'|'M'|'E'|
|'M'|' '|'4'|'8'|','|'#'|'4'|'0'|'0'|'1'|'6'|128| 0 |218|
|129|255|255|218|129|128| 0 | 37|126| 0 | 0 | 37|126| 10|
