ASCii- formatted data consists of waveform data values converted to the
currently selected units, such as volts, and are output as a string of ASCII
characters with each value separated from the next value by a comma. The
values are formatted in floating point engineering notation. For example:
8.0836E+2,8.1090E+2,...,-3.1245E-3
The ASCii format does not send out the header information indicating the number of bytes
