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 is only available for modules with
a single OTDR port). The wavelengths available to select depend on the module type.
Acquisition Mode
Select the type of acquisition to be performed:
Manual The acquisition parameters Pulse / Range / Resolution can be set
by the 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 "Acq. Time"
page 15 ).
Smart Acq (not available in Multimode) SmartAcq is a fully automated acquisi-
tion process which uses different pulse widths for a single wave-
length to maximize the detection. The multiple acquisitions are
combined to form a single graph and table of events per wavelength,
combining the most relevant sections of each pulse.
Range
The possible range depends on the pulse length selected. This range is given for each
pulse length in the paragraph
“Ranges” on page 109 . This parameter is only configu-
rable if Acquisition parameter is set to Manual .
Auto allows to detect automatically the range.The range is selected as a
function of the detection of the end of the fiber.
Pulse
. Parameter selectable only if Acquisition parameter is set to Manual . The range of
selectable pulse widths varies by module type and will have values in the range 3ns to
20us.
