Description: This object represents the attribute that is being snapshoted by
the hardware. When a snapshot request is issued up to 4 simultaneous
radio signal attribute may be captured at once. 
The 4 attributes are specified by bit OR'ing the snapshot types
identified below. When a snapshot specification
is started all the specified attributes are captured simultaneously.

The TX and RX types cannot be mixed. RX, Sync types can be mixed.

When a snapshot request is issued up to four radio signal attributes
may be requested at once, one from each set:

What is cwrSnapshotType?

An Integer32, read-create, specifying which radio-signal attributes the hardware should capture in a snapshot, with up to four attribute codes bit-OR'd together for simultaneous capture. The MIB notes TX and RX attribute types cannot be mixed in one snapshot, so this field also constrains which attribute combinations are even valid to request together. For example, an engineer wanting to correlate receive power with SINR at the exact same instant would bit-OR those two RX-side attribute codes into cwrSnapshotType to capture both simultaneously.
