Using the Instrument
Analyzer Operating Modes
When the analyzer enters the filter mode, the sweep stops with the analyzer
filter tuned to the center wavelength. (If a marker is on, the analyzer filter is
tuned to the marker wavelength.) The last trace remains displayed to show
the input spectrum before the filtering. A marker shows the wavelength of the
preselection. You can change the filtered output (preselection) wavelength by
adjusting the marker’s position, then connecting the monochromator output
to another instrument. If the input spectrum changes, reconnect the mono-
chromator output, then press the Take Sweep softkey to capture a new sweep.
The single mode filter can be used in conjunction with the Agilent 86130A bit-
alyzer error performance analyzer and/or the Agilent 86100A infinium digital
communication analyzer. Time resolve chirp (TRC) measurements use the
Agilent 86146B Option TRC and the Agilent 86100A digital communication
analyzer.
