These files contain floating point representations of a sine wave. The format of the data is:

^  Byte    ^  Length  ^  ^
^  Offset  ^  Bits    ^ Description ^ 
|   0  |  16  | Frame sync pattern 0xeb90 | 
|  16  |  64  | IEEE-754 floating-point value sine wave 1 | 
|  32  |  64  | IEEE-754 floating-point value sine wave 2 |
|  48  |  64  | IEEE-754 floating-point value sine wave 3 |
|  <zero padding>  |||
| Final 2 Bytes	 |  16  | Unsigned integer sequential count |

These data sets are also interesting because time packets occurs at a 100 Hz rate. Most data sets have time packets at a 1 Hz rate.
