Cable Velocity and DistanceVelocity is designed in a cable at the time of its manufacture

Velocity is expressed as a fraction of the speed of light

Examples: .66c or 66.7c

Time 2

X Velocity = Distance

20 n Sec 2

X .66c (648,172,800ft/sec) = 6.48 feet

Impedance “Z”

Z = 50 OhmsZ = 100 Ohms

14

Cable Impedance (Z) and ReflectionsImpedance is a factor of both the conductor and the dielectric of the insulation between the conductor & shield or twisted pairs

Any deviation from the manufactured Z will cause reflections

Z = ∞Ω Open

TraceMICRO FAULT – Locate minute defects in coaxTEST LEAD NULL – Remove unknown test lead length from measurement

CablesVELOCITY SEARCH – Pin-Point an installed cable’s

true VF based on cable’s known length or known distance to an event.

SAMPLE A CABLE – Find the VF for a cable sample to apply to all the cable in that box, reel or lot number.

For small kinks and crushesin coax cablesTDR’s normal display will

shift to an amplified reflectiondisplay with Z0 as base line . In this example a fault barelyseen in the normal impedance display shows up clearly.

51

Cleaning Your 20/20 TDR1. Always spray cleaners and rinse water on a soft cloth, do NOT

spray directly on the TDR

Soft CasesThe soft case should be cleaned the same as the instrument. Usea soft bush to remove tough dirt. Do NOT immerse in water or dryin a dryer. Wash and Dry separately, both instrument and case shouldbe dry before enclosing the instrument in the case.

2. Typical Grime – Use a mild non-abrasive detergent like 409® in water or glass cleaner (non-ammonia) and rinse water to clean3. Cable Gel – User liquid “citrus” cleaner to remove4. Tar, creosote or adhesives – Use WD40® followed with mild

detergent and water
