Making a Measurement

Making a Measurement

This procedure will introduce you to the Agilent 86140B series optical spec-
trum analyzer front panel controls. By following this procedure you will do the
following:

• Perform an auto alignment
• Perform a peak search
• Use a delta marker
• Print the display

Refer to “The Menu Bar” on page 1-17

and

“The Softkey Panels” on page 1-18

.

Instrument setup

A source signal must be present at the input of the optical spectrum analyzer.
In this procedure a Fabry-Perot laser is used as the source. You can use
another source or the optional 1310/1550 nm

EELED

. If another source is being

used, the display will differ from those shown.

To set the OSA to a known state

• Press the front-panel

Preset

key to set the instrument to a known state. For

a complete description of preset conditions, see
