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 in form ation for fre-
quency or wavelength when the instrument is in a non-zero span . The delta
markers have their own setting. This setting controls all four ba ndwidth mark-
ers.
Delta Marker Units
Sets the delta marker X-axis immediately displayed information for fr eque ncy
or wavelength when the instrument is in a non-zero span. The bandwidth
markers have their own setting. This setting controls all four de lta 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 fre-
quency 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 marke rs 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 i s ON,
the bandwidth 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 def a ult state is ON. If
interpolate is OFF, for negative NDB values, the bandwidth markers will be at
values closest to and more negative than the NDB value. For posit ive NDB val-
ues, the bandwidth markers will be at values cl os es t to an d mor e p osi ti ve t han
the NDB values. This will typically result in a wider bandwidth me a s urement.
