Abstract
Embodiments of the present invention provide a test and measurement instrument that displays acquired data on a logarithmic scale without intensity banding. The test and measurement instrument processes the acquired data before it is displayed by appending pseudo-random sub-LSB (least significant bit) values to it. When the processed acquired data is displayed on a logarithmic scale, the pseudo-random sub-LSB values fill in the gaps between discrete power levels, thereby eliminating intensity banding and providing a smooth, visually pleasing display.
