ARGUS Copper tests
The copper tests for ARGUS 300 and ARGUS 260 enable you to detect dangerous
voltages and currents early on and reliably assess the physical quality of the line –
particularly when DSL synchronisation is not possible or the data rate is low due to
asymmetry, interference sources or other mechanical line problems.
Technical features of the ARGUS copper tests at a glance:
Copper tests Multimeter
-
Multiple, preconfigured measurement profiles can be executed as an
auto test
.
-
Voltage measurement
enables measurement of the supply voltage, as well as
external voltages caused e.g. by contact between two wires or isolation faults.
-
With the aid of
capacitive symmetry measurement
, it is possible to detect asymmetry
in the subscriber line that can result in signal distortions or transmission errors.
-
Capacitance measurement
detects interruptions as well as typical input capacitances
of connected devices and enables estimation of line lengths.
-
Isolation resistance measurement
reveals damage to cable isolation, moisture
penetration or oxidised contact points.
-
With the aid of
resistance symmetry measurement
, it is possible to detect irregula-
rities in the subscriber line that can result in signal distortions or transmission errors.
-
Resistive fault location (RFL)
can display resistance to fault (R
x
), distance to fault,
resistance from fault to short circuit (R
y
), loop resistance (R
s
), line length, and fault
resistance (R
fault
).
-
Loop resistance measurement
aids detection of short circuits and estimation of line
lengths.
-
DC current measurement
can be used to detect emergency, external and normal
power feeds as well as breaks in the line.
-
Unbalance measurement (LCL):
This measurement uses a frequency of 1 MHz to
measure asymmetry in a line pair.
-
NEXT measurement:
Measurement of near-end crosstalk at a frequency of 1 MHz.
-
Signature detection
is used to detect the signatures and test terminations (PPAs)
connected to the subscriber line.
-
The
fast cable check
verifies the correctness of a three-pole (Tip/Ring/Ground)
connection.
-
The
integrated remote kit control
lets you remotely set the line end to the desired
state either manually or automatically using a variety of electronic instrument kits.
Copper tests Oscilloscope
-
Line Scope:
High-performance realtime Line Scope with display in time and frequency
range (FFT) up to 35 MHz
-
TDR:
Time domain reflectometer to measure line lengths and locate faults
