Laser
The acquisition will be carried out on the wavelength(s) selected (for multiple-wave-
length modules). In case of a multi-wavelength module, select All to perform a measure-
ment for all the wavelengths available (this parameter visible exclusively on modules
with one single OTDR port). The possible values depend on the module used.
Acquisition Mode
Select the kind of acquisition to be performed:
Manual
The acquisition parameters Pulse / Range / Resolution can be set
by user.
Auto
The acquisition parameters Pulse / Range / Resolution are defined
automatically and cannot be modified
The Measurement time will be set to Auto, but can be modified (see
page
34).
Smart Acq.
(not available in Multimode)
This parameter allows to launch a short acquisition before the stan-
dard one.
The first acquisition is performed with the shortest pulse in order to
detect more precisely the events at the beginning of the fiber.
Range
The possible range depends on the pulse length selected. This range is given for each
pulse length in the paragraph
sively configurable if Acquisition parameter is set to Manual. It depends on the module
used
Auto
allows to detect automatically the range.
In Auto mode, the range is selected as a function of the end of the fiber.
Pulse
The available values depend of the module used. Parameter selectable only if Acquisi-
tion parameter is set to Manual.
