Cable Setup
The Cable Setup tab allows you to
configure parameter values for the
cable.
Each parameter and button is
described below:
³
Cable Type defines the gauge of
the cable in use. If wire gauge is
measured in American Wire
Gauge (AWG) units, the available
choices are: AUTO, 19 AWG, 22 AWG, 24 AWG, or 26 AWG. For mm
gauge wire, the available choices are: AUTO, 0.32 mm, 0.40 mm,
0.50 mm, 0.60 mm, 0.65 mm, 0.80 mm, 0.90 mm, or 1.20 mm.
³
Cable Fill 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
updating the Cap. T/R-GND field.
³
Capacitance T-R (nF/km or nF/mi) allows you to specify a value for the
capacitance per length constant.
³
Cap. T/R-GND (nF/km or nF/mi) allows you to specify a value for the
capacitance per length to ground constant.
³
Resistance (Ohm/km or Ohm/mi) allows you specify a value for the
resistance constant of the cable.
³
Attenuation (dB/km or dB/mi) allows you to specify a value for the
reduction in signal strength or insertion loss of the cable.
³
VOP allows you to set the velocity of propagation for the cable as a
ratio of the speed of light. Enter a value between 0.400 and 0.999.
³
Restore Defaults allows you to reset cable parameters for the selected
cable to the standard default values.
