Function Reference
Marker Setup
Setup Panel Selections Normal Marker Units
Sets the X-axis immediately displayed marker information 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 immediately displayed information. This setting controls all four normal markers. The
bandwidth and delta offset markers have their own settings.
BW Marker Units
Sets the bandwidth marker X-axis immediately displayed information for frequency or wave-
length when the instrument is in a non-zero span. The delta markers have their own setting. This
setting controls all four bandwidth markers.
Delta Marker Units
Sets the delta marker X-axis immediately displayed information for frequency or wavelength
when the instrument is in a non-zero span. The bandwidth markers have their own setting. This
setting controls all four delta markers.
Normal/Delta Marker Interpolation
Turns the normal/delta marker interpolation on or off. When interpolation is , the normal/delta
ON
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.
When interpolation is off, the marker will be placed at the trace point nearest the requested
value.
Bandwidth Marker Interpolation
Turns the bandwidth marker interpolation on or off. When interpolation is , the bandwidth
ON
markers will be placed at the exact number of dB (NDB) from the normal marker if within the
trace range. The position of the marker will be linearly interpolated between two trace data
points. The default state is . If interpolate is , for negative NDB values, the bandwidth mark-
ON OFF
ers will be at values closest to and more negative than the NDB value. For positive NDB values,
the bandwidth markers will be at values closest to and more positive than the NDB values. This
will typically result in a wider bandwidth measurement.
