Icom IC-R8600 - I;Q Data Details; D 16-Bit Long I;Q Data; D 24-Bit Long I;Q Data

D 24-bit long I/Q data
Data format:
The I/Q data is composed of 3 parts: “I” signals, “Q” signals and Synchronous signals.
Each data length is: “I” = 24 bits (3 Bytes), “Q” =24 bits (3 Bytes), Synchronous data=48 bits (6 Bytes).
(The byte order is in the little-endian format.)
D 16-bit long I/Q data
Data format:
The I/Q data is also composed of 3 parts: “I” signals, “Q” signals and Synchronous signals.
Each data length is: “I” = 16 bits (2 Bytes), “Q” =16 bits (2 Bytes), Synchronous data=32 bits (4 Bytes).
(The byte order is in the little-endian format.)
• The synchronous data is to be followed by an “I” signal.
• I/Q data range is “–8387967 (0x800281) ~ +8387966 (0x7FFD7E).”
The Synchronous data:
• Data length is 48 bits (6 bytes).
• The Synchronous data is composed of 6 bytes in total: 0x8000 (2 bytes), 0x8001 (2 bytes) and 0x8002 (2 bytes).
• The synchronous data is to be followed by an “I” signal.
• I/Q data range is “–32767 (0x8001) ~ +32767 (0x7FFF).”
The Synchronous data:
• Data length is 32 bits (4 bytes).
• The Synchronous data is composed of 4 bytes in total: 0x8000 (2 bytes) and 0x8000 (2 bytes).
• The Synchronous data is inserted into the I/Q data, at the following rate.
• The Synchronous data is inserted into the I/Q data, at the following rate.
