Symmetric 0

Specifies that the offset channels are symmetrically located around the reference channel. The number of offsets on either side of the reference channel is specified by the ACP Num Offsets property. In symmetric mode, the Center Frequency property specifies the frequency of the reference channel, expressed in Hz.
In-band 1

Specifies that the measurement is performed over all the channels as specified by the standard. For BR and EDR packets, 79 channels starting from 2.402GHz to 2.48GHz are used for the measurement. For LE packets, 81 channels starting from 2.401GHz to 2.481GHz are used for the measurement. In In-band mode, the Center Frequency property specifies the frequency of acquisition which must be equal to 2.441GHz. Configure the Channel Number property to specify the frequency of the reference channel.
