Frequency Tests
236 MAX-635G
Load Coils
Load Coils
The Load Coils test allows you to detect the presence of load coils, which
are detrimental to the use of DSL technologies on the line. If a load coil is
detected, use the TDR (time domain reflectometry) test to quickly locate
and remove it from the cable.
Detection
The Detection function specifies the presence or
absence of load coil in the cable section, and displays
the number of load coils in the line and measured
values in graphical form.
Current Group is the current test group name, for
example Frequency Tests.
Current Test displays the test being measured.
Here you can switch to another test from the given
list. However, this action will terminate the
ongoing measurement test.
Cable Parameters:
Cable Type displays the ID, Cable Name and Fill, and allows you to
select an entry (with its associated parameters) from the current
Cable Book, to use for testing. The selection is not saved when
leaving the test. The current Cable Book entry is shown by default.
Cable Fill read-only entry is the type of material the cable is filled
with: Aircore, Jelly, Pulp, 5 PR, or 2 PR. Setup in the Cable Book.
VOP read-only entry is the velocity of propagation for the cable
defined as m/μsec (meters per microsecond), a ratio, or
percentage of the speed of light. Setup is in the Cable Book.
Cable Temperature allows you to change the temperature of the
cable under test in either °F or °C.
