An apparatus, method and computer program product for presenting burst images are provided. Each of the test circuits is operable to produce one or more signals for analyzing the effects of on-chip noise on signal propagation. For example, a codeword can be mapped onto a plurality of layers which are equal in number to a channel rank of a radio channel to be used for the transmission. A font bank receives the one or more SRE codes from the SRE code store and defines such codes via a font. A scanning unit relatively moves at least one of the ejecting head and a stage in the X-axis direction with respect to the other between the first scan period and the second scan period.
