A device for supplying flow across a combustor includes an axial fluid injector configured to circumferentially surround at least a portion of the combustor. Output circuitry, such as analog and pulse output circuitry, provides transmitter output related to flow through the flowtube. Such a system and method may include at least one programmable control device having an assigned memory device, in which a plurality of session scripts is able to be stored, which each contain a predefined test procedure, and at least one session computer connected to the control device and has a plurality of mutually independent connection interfaces for executing at least one session script. It sends these two recording streams alternately to the media-recording unit, thereby recording the rerecording stream and new recording stream alternately. In addition, the configuration section allocates numbers to a plurality of first control channel elements included in the first search space in an ascending order, and allocates numbers larger than or identical with the numbers allocated to the first control channel elements to a plurality of second control channel elements included in the second search space.
