Filter Marker Tune
Filter Marker Tune
For Agilent 86144B/86146B Filter Mode only.
Tunes the wavelength of the preselector. During the preselector instrument
mode, the instrument acts as an optical filter at a fixed wavelength. Although
the instrument is not sweeping the displayed input range, the last sweep
remains displaying the input spectrum. With filter marker tune softkey
selected, use the front panel knob, step keys, or numeric keypad to change the
preselector wavelength. Press Take Sweep to update the displayed response
at any time.
The amount of filtering is determined by the resolution bandwidth setting.
Narrower resolution bandwidth settings will filter the signal more. If the reso-
lution bandwidth is changed, Filter Marker Tune must be reselected to tune
the monochromator. Marker movement will not tune the monochromator
unless Marker Tune is active.
The front panel, single mode preselector monochromator connector allows
the channel drop capability to the Agilent 86130A BitAlyzer error perfor-
mance analyzer or the Agilent 86100A Infinium digital communication ana-
lyzer.
Note During filter mode, the noise marker, delta marker, and OSNR marker are
disabled.
