Markers Window
The 89600 VSA shows marker values in the window. The following illustration shows some of the marker readouts available.
For information on marker readouts with spectrogram markers, see About Spectrogram Markers.
The label preceding the marker value indicates how the marker value was derived:

indicates that marker N is a delta marker with reference marker TR, where T is the reference marker's trace (if different from the delta marker's trace) and R is the reference marker.
The x and z values for delta marker N are calculated by subtracting reference marker TR's x and z positions from marker N's x and z positions.
Marker N's y-axis position is calculated as the ratio: (marker N power) / (marker TR power).

NAN (Not A Number) is displayed when the marker value is invalid (for example, if the marker value is the result of a math function that divides by zero).
INF (Infinity) is displayed when the marker value exceeds approximately 3.4E+38.
Polar Display Marker Readouts
The Polar Format box in the tab of the Markers dialog box determines the readout for a 2D (I/Q) trace format. The choices are between or . The default is .
