Test Selection
The
Test Selection
page allows you to select the test
types to include in the auto test, and set a
Pause
between tests by selecting
ON
or
OFF
. When FED is
Enabled
on the
FED Setup
page,
Pause
is replaced
with
FED State
parameters. All listed tests have a fixed
duration (snapshot) and are not continuous. Graphs are
not displayed.
The following tests are available:
Voltage
detects AC RMS and DC voltages in
the line.
Current
checks for AC RMS and DC currents
in the line.
Resistance
uses DC current to measure the
opposition to flow, or resistance, between each
of the lead combinations. It is also used to
identify possible faults, and to measure the
resistance of the twisted pair cable for
estimating loop length.
Resistive Balance
measures and compares
the resistance of each leg.
Isolation
measures the quality of insulation or
sheathing for the copper pairs.
Capacitance/Opens
measures the
capacitance of the cable for estimating loop
length.
VF Noise
measures voice frequency noise in
the line.
Power Influence
measures the effects that 50
Hz and 60 Hz power line (AC Mains)
interference has on the circuit under test.
VF Impulse Noise
measures the random
occurrences of energy spikes in the voice
frequency range that have random amplitude
and spectral content.
WB PSD Noise
measures power spectral
density noise.
WB Impulse Noise
measures the irregular
occurrences of energy spikes in the wideband
range that have random amplitude and spectral
content.
VF/AC Balance (Active)
is very useful in
identifying loops that will suffer from crosstalk.
WB Balance
ensures that the balance ratio for
the twisted pair complies with applicable
standards so as to reduce the effects of
common-mode voltage to ground.
WB Attenuation
measures the dissipation of
power of a transmitted signal as it travels over
the copper line.
Load Coils
detects the presence of load coils
in the line.
TDR
characterizes and locates faults in cables
under test.
DRP
(Data Rate Prediction) is a software
option. When enabled, the prediction
calculation is based on the PSD noise and
wideband (WB) attenuation measurement
results up to 35 MHz. Ensure
WB Attenuation
and
WB PSD Noise
tests are selected for
DRP
to function. It is recommended to run the
DRP
test on open lines only (non-terminated). For
FED support, the FED state for both
WB
Attenuation
and
WB PSD Noise
must be set
to
Open 0
.
Return Loss
measures the loss of power in
the
Sweep
frequency returned/reflected by a
discontinuity in a transmission line.
To select the tests:

all the tests and highlight the desired
parameter.
