ARGUS displays possible interference
sources on the copper twisted pair
directly.
In this example, after the input pulse
(starting at 0 meters) we can see a second
pulse that spikes at approx. 150 m. This
can indicate a 150 m long line that is open
at its end.
The adjustable range, the gain and the
graph functions permit more detailed
analysis.
To ensure optimum detection of pulse
reflections, match the function for adjust-
ing the gain (y-axis) with the reduction/
enlargement of the range shown (x-axis).
ARGUS always starts with the lowest gain
(-26 dB) at a range of 1500 meters.
Gain-Y: Sets the gain
from 0 dB, +6 dB, +20 dB, +26 dB,
+30 dB, +36 dB, +51 dB, +51 dB
The measurements with the TDR can take
place in a measuring range of from 1 to
6000 meters. The resolution is approx.
0.025 % of the displayed measuring
range.
The accuracy is approx. ±1 % of the
measuring range. When determining
the distance, try to determine the
start of a pulse where possible, and
not the relative maximum.
Range-X: Sets the displayed
measuring range. Every press of
the cursor key halves or doubles
the displayed range.
