The marker table function can be used to display a list of all of the active markers. It is sometimes necessary to keep track of several points on a signal trace. Multiple markers are valuable for the measurement of component response, such as Iilters, in tracking generator swept measurements. The multiple markers feature allows you to place up to four markers on a trace. Using the marker table all the markers on the display are annotated in a window below the trace. The information is updated at the end of each trace or whenever a marker is activated or updated. Each marker can be independently set to read frequency, (sweep) time, inverse (sweep) time, or period (inverse frequency). This allows you to measure pulse repetition rate, rise and fall time, and the period of a trace, all at the same time.
The marker information can be displayed in absolute amplitude and frequency or it can be in delta amplitude and frequency using one marker as the reference. The marker table can also be set to display the marker amplitudes relative to the display line. This marker format is only available when using the marker table function.
