Real time spectrum analyzer with zoom display

摘要

The described test and measurement instrument includes a processor for generating a bitmap image (412) from an input test signal, a user interface for identifying a portion (420) of the bitmap image, and a second image generator structured to generate a second image (432) from the identified portion of the bitmap image. The second image may be a zoomed image from the original bitmap, and the images may be time-corrected before being displayed.
