is the channel to operate on. Valid options are rx/RF 0, rx/RF 1, tx/RF 0, and tx/RF 1. For this node, scope is used to determine which daughterboard to update the ATR state of and whether to update the gain of Rx or Tx.
The specific ATR register to write to. The registers correspond to the four states each daughterboard supports. The daughterboard state is set based on whether Rx and Tx are enabled or disabled, using the Enable Front End node. It is safe to call the Enable Front End node after writing to the ATR registers.
The gain of the Rx or Tx signal. This gain is not coerced. Verify the input is in the daughterboard gain range.
Object created by the Open node and used as the session handle for the USRP RIO nodes.
niUsrpRio session (out)
The niUsrpRio session used in all subsequent USRP RIO host nodes.
