+Complex signed 14-bit little endian IQ sample
+
+
+Description
+===========
+
+This format contains sequence of complex number samples. Each complex
+number consist two parts, called In-phase and Quadrature (IQ). Both I
+and Q are represented as a 14 bit signed little endian number. I value
+comes first and Q value after that. 14 bit value is stored in 16 bit
+space with unused high bits padded with 0.
+
+**Byte Order.**
+Each cell is one byte.
