
FED Type is enabled when FED is set to Auto
or Manual . If Auto is selected, you can choose
between TS125 or UFED IIB .

When UFED support is enabled:
o
the Isolation test voltage source will
automatically be limited to 125 V,
Return Loss
test termination to 120 Ω,
and VF/WB Impulse Noise tests
duration to 15 min only.
o
MMT (maximum measurement time) is
determined for every test.
For tests, which run in Continuous
mode, the MMT is set to 20 s allowing
you to observe continuous results in
numerical or graphical format. At the
end of the MMT, the continuous test is
terminated. However, due to UFED
limitation, the
Continuous Isolation
resistance test will act the same as the
test in
Snapshot mode and terminate
after the Soak Time period expires.

If Manual is selected, the FED Type is set to
TS125 by default. When FED is Manual , you
can set the FED to a desired state
independently from the one defined currently in
the FED setup for a particular test. This state
will be kept indefinitely until you set the FED to
another one, change the mode to Auto, or
disable the FED.

The Manual state of the FED Control is not
saved in the profile and is only kept for the time
of the current session. If you leave the copper
application, at next startup FED will be set to
the value saved in the profile:
Disabled or
Auto .

Manual Setup includes 5 options:
o
Open 0
o
T-R/A-B Shorted 1
o
T-R-G/A-B-E Shorted 2
o
Pass Through/Exchange Connect 3
(default)
o
ID Tone 4

Set FED button activates the state defined in
the Manual Setup control.

Test Status displays a communication with
FED status message.

FED Factory Default button allows you to
restore the factory defaults for the following:
o
Single Test defaults sets the default
FED state values for all the individual
tests, except
Auto Test .
o
User Auto Test defaults sets the
default FED state values for Auto
Test .
o
All these options sets the default FED
state values for all tests.
FED States are displayed in the Current Test line as a
numeral on the right-hand side of the FED icon, for
example
. Numerals match the following states:

0 = Open

1 = T-R/A-B Shorted

2 = T-R-G/A-B-E Shorted

3 = Pass Through/Exchange Connect

4 = ID Tone

5 = Terminated (100
Ω, 120 Ω, 135 Ω, 600 Ω)
Note: A line termination of 150 Ω is not supported by
the FED.

6 = Crosstalk NEXT

7 = Transmit

8 = None
Note: For all FED States other than Pass
Through/Exchange Connect , the Dialer tab is
disabled. If the dialer is already running before
the test starts, the dialer will be stopped on entry
of the test with a message saying
Dialer cannot
be used, hence dialer will be stopped. - similar
to FaultMapper test.
