Cable analysis
section above provides a simple introduction to cable analysis and in many cases
can deliver enough information for the user. Using the menus more extensively provides engineers and
technicians with a very powerful analyzer capable of helping them find a wide variety of cable details
such as taps, repeaters and water ingress.
Config menu details
Pressing the
button (Button 5) more than once scrolls the highlighter around the Config submenu
allowing you to select a parameter or function, and to change it using the arrow buttons:
Pulse width Vary the pulse width using the arrow buttons. The up and right arrows increase the pulse
width, while the down and left arrows decrease it.
A wider pulse has more energy, meaning it can travel further along a cable, but a narrow
pulse can make it easier to see cable features at shorter distances
VOP
above. Change the VOP, otherwise known as the
Dielectric, to match the cable under analysis for accurate distance measurement.
The left and right arrow buttons change the VOP by 1%. The up and down arrows change
the VOP by 0.1%.
Out Z
Match the output impedance of the 1205CXB to the cable for improved signal transfer
Thres
Threshold is the minimum voltage range over which the 1205CXB detects an event. This
means that you can set the sensitivity of the unit for the size of fault at which it will place
the cursor during an automatic search (see below)
Avg
Set an averaging filter to reduce noise on your signal
Func
your options are to view the following signals:
the cable being analyzed (CABLE)
a saved waveform (LOAD)
the difference between CABLE and LOAD (C-L)
CABLE and LOAD at the same time (C&L)
NOTE: press the
button (Button 13) to offset the two waveforms from each other
Search
Tell the 1205CXB to perform an automatic search
Cursor menu details
Pressing the
button (Button 6) more than once toggles between Cursor 1 and Cursor 2. Use the
arrow buttons to move the selected cursor to the left or right.
