Detailed Description

Information concerning the scaling factor and processing parameters.

Format:

Variable length Data Item comprising a first part of three octets, followed by one-octet extents as necessary

Structure (First Part):

• Bits 24-20 (f): Scaling factor (2's complement, bit 24 is sign bit)
• Bits 19-17 (R): Current reduction stage (0=Normal operation)
• Bits 16-2 (Q): Processing parameters (application dependent)
• Bit 1 (FX): Field extension indicator

Scaling Factor Examples:

• f = 4: LSB = 0.125 NM (for 32 NM range radar)
• f = 7: LSB = 1 NM (for 250 NM weather radar)
• f = -1: LSB = 1/256 NM (high precision)
