The Marker Setup panel

Normal Marker Units

Sets the X-axis readout for frequency or wavelength when the instrument is in a non-zero span. This setting controls only the normal marker X-axis and the delta reference readout. This setting controls all four normal markers. The bandwidth and delta offset markers have their own settings.

Bandwidth Marker Units

Sets the bandwidth marker X-axis readout for frequency or wavelength when the instrument is in a non-zero span. The delta markers have their own set- ting. This setting controls all four bandwidth markers.

Delta Marker Units

Sets the delta marker X-axis readout for frequency or wavelength when the instrument is in a non-zero span. The bandwidth markers have their own set- ting. This setting controls all four delta markers.

Normal/Delta Marker Interpolation

Turns the normal/delta marker interpolation ON or OFF. When interpolation is ON, the normal/delta markers will be placed at the exact wavelength or frequency value selected if it is within the trace range. The marker will linearly interpolate between two trace data points. The default state is OFF.

This setting controls the interpolation state for all four markers when in the normal or delta mode.
