-221 Settings conflict; Change to I/Q state or source causes AM WB to be
     turned off.
            The modulation type AM WB requires that I/Q is on and that the I'Q
            source is set to external. This error is reported when the user
            turns I/Q off or changes the I/Q source to something other than
            external or sum. When this happens AM WB is turned off.
-221 Settings conflict; Changing one of the setup parameters caused the
     clock rate to be out of range. The clock rate has been clipped to its
     new lower limit.
            Clock rate limits are dependant on of the other setup parameters.
            This error is reported when the parameters change causing the clock 
            rate to be below the new limits.

-221 Settings conflict; Channel #{value} must be on for any transport
     channel following it to be on. All transport channels following
     channel #{value} have been turned off
            Transport channels must be turned on sequentially. Therefore, all
            transport channels with a higher number than a channel that is
            turned off will be automatically turned off.
