Using Analyzer Display Markers

The analyzer markers provide numerical readout of trace data. You can control the marker search, the statistical functions, and the capability for quickly changing stimulus parameters with markers, from the (jMarker) key.

Markers have a stimulus value (the x-axis value in a Cartesian format) and a response value (the y-axis value in a Cartesian format). In a polar or Smith chart format, the second part of a complex data pair is also provided as an auxiliary response value. When you switch on a marker, and no other function is active, the analyzer shows the marker stimulus value in the active entry area. You can control the marker with the front panel knob, the step keys, or the front panel numeric keypad.

w If you activate both data and memory traces, the marker values apply to the data trace.

nIf you activate only the memory trace, the marker values apply to the memory trace.

H If you activate a memory math function (data/memory or data-memory), the marker values apply to the trace resulting from the memory math function.

To Use Continuous and Discrete Markers

The analyzer can either place markers on discrete measured points, or move the markers continuously along a trace by interpolating the data value between measured points
