Coaxial Measurements with OMNISCANNER
Coax Tests
In coaxial cable, an insulated wire runs
through the middle of the cable and a second
wire, called the shield, surrounds the insulation of the inner wire like a
sheath. The outer insulation jacket wraps around the second wire.
The Coax Tests screen displays the measured Length, Termination,
Impedance, and Resistance.
The Length function measures the cable length.
OMNISCANNER will display the overall length in
meters or feet. If NEF (No End Found) is displayed
instead of a value, the cable is either too long or
terminated in its characteristic impedance.
The Termination function displays whether a
cable is open or shorted .
When the field Length: displays NEF, the Termination will display .
Impedance defines the relationship of voltage and current in an
electrical circuit.
Each Cable or transmission line is designed to have specific impedance,
which allows proper matching to the currents of the transmitter and
receiver. OMNISCANNER measures the characteristic impedance of the
coax cable in Ohms.
OMNISCANNER displays the Resistance in Ohms.
If the button was used to
execute the coax test, the result can be stored with
a Project Name and Circuit ID.
Press to open the SAVE AUTOTEST screen.
