Copper Test 33

Cable Book

 Cable Fill Material allows you to select the type of material the cable

can be filled with. Changing the selection to Aircore, Jelly, Pulp 5 PR,

or 2 PR influences the cable capacitance per length, automatically

updates the Capacitance T/R to GND field.

 Capacitance T-R allows you to specify a value for the capacitance per

length constant.

 Capacitance T/R to GND allows you to specify a value for the

capacitance per length to ground constant.

 Resistance allows you specify a value for the resistance constant of the

cable.

 Attenuation @ 300 kHz allows you to specify a value for the reduction

in signal strength or insertion loss of the cable.

 Velocity of propagation allows you to set the velocity of propagation

for the cable as a ratio of the speed of light.

 Temperature allows you to specify the temperature of reference at

which all cable parameters have been measured.

 Add button, tap the Add button to append the new cable entry to the

end of the Cable Book. If the maximum number of Cable Book entries

has been reached, delete an entry before adding a new one.
