Appendix I: Custom Cable Settings
The SARK-110 allows the user to specify three custom cable settings by supplying a special text
file stored on the analyzer’s disk. The file name must be “custcab.txt” and the format for each
cable entry in the file is as follows:
legend, Z0, VF, K0, K1, K2
Where:
o legend: string to be display in the preset menu (max length: 20)
o Z0: characteristic impedance
o VF: velocity factor
o K0: DC resistance, dB/100ft
o K1: coefficient for conductor loss, dB/100ft
o K2: coefficient for dielectric loss, dB/100ft
Example:
Test cable 1, 50, 0.68, 0.063897, 0.192292, 0.000051
Test cable 2, 60, 0.78, 0.073897, 0.193292, 0.000061
Test cable 3, 70, 0.88, 0.083897, 0.194292, 0.000071
