Bandwidth Marker Interpolation (Marker Setup Panel)
Turns the bandwidth marker interpolation on or off. When 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 the two nearest trace data points.
The default state is on. If interpolate is off, for negative number of dB (NDB) values, the band-
width markers will be at values closest to and more negative then 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.

Bandwidth/Sweep
Accesses the menu that allows you to change bandwidth, sweep settings, fiber selection, trigger
mode, and ADC sync. You can also access these functions from the Measure menu Bandwidth/
Sweep selection. The function keys include:
• more BW/sweep functions
• repeat sweep
• res BW
• select fiber
• single sweep
• sweep time
• video BW
BW Marker Units (Marker Setup Panel)
Sets the bandwidth marker X-axis readout for frequency or wavelength when the instrument is in
a non-zero span. The available selections are nm, µm, Ang, GHz, and THz. The default unit is nm
(nanometers). This setting controls all four bandwidth markers. The normal and delta offset mark-
ers have their own settings.
