183Scaled by Frequency Scale Factor (bytes 335-336)

184Scaled by Frequency Scale Factor (bytes 335-336)

185000b = NB FHSS, 001b = Carrier - WB FHSS, 010b = Carrier - Broadband, 111b = Interference

186Value sent as (value in dBm ￿ 1000) + 270,000

187If Status Byte 9, bits 1-3 equal 111b, then value will be calculated power for the interference trace as a NB FHSS signal. Otherwise, these bytes represent the calculated carrier power.

188Value sent as (value in dBm ￿ 1000) + 270,000

189If Status Byte 9, bits 1-3 equal 111b, then value will be calculated power for the interference trace as a WB FHSS signal. Otherwise, these bytes should be ignored.

190Value sent as (value in dBm ￿ 1000) + 270,000

191If Status Byte 9, bits 1-3 equal 111b, then value will be calculated power for the interference trace as a Broadband signal. Otherwise, these bytes should be ignored.

192If Method is % of power, then the value is dB Down ￿ 1000. If the Method is db Down, then the value is %.
