Markers
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.
