Abstract
As frequency spectra are produced continuously at a speed that is too fast for realtime display, they are accumulated in a memory. After a block of these frequency spectra have been accumulated, they are read back from the memory and displayed on a display device that permits the display of multiple frequency spectra along a time axis. Markers allow delta-time measurements to be made between different spectra in the display. Continuous storage into a circular memory can be stopped and the display of the accumulated frequency spectra started by the detection of the occurrence of a pre-defined spectra event.
