ARGUS Copper Test Manual
3.3.2 Examples
The following signal forms can help you in interpreting the reflection responses that
ARGUS displays.
Open cable
The reflected pulse is positive. No proxi-
mate interference sources or the far end of
the line can be seen.
Short-circuit
The reflected pulse is negative. No proxi-
mate interference sources or the far end of
the line can be seen.
Mismatch
Different line cross-sections were used.
The greater the mismatch, the greater the
amplitude of the reflection.
Poor contact point
A poor contact between two lines distorts
the reflection into an S-shape. The worse
the contact, the greater the reflection.
