http://www.irig106.org/sample_data/netacquire-pcm-sine-wave.zip

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.
