A flexible microwave antenna assembly for a surgical ablation instrument capable of conforming to a tissue surface for ablation thereof. In one embodiment for optical fiber communications links, a data test pattern is applied to the transmitter under test and the resulting optical output is captured, for example by a sampling oscilloscope. Furthermore, physical lines of the memory towers are shared by multiple cache lines. The positioning structure is disposed on the base for movably positioning the frame on a plane above the base. The processor then retrieves from the network address, using the locations on the first interactive document, a second page description.
