How Does a TDR Work? The same as RADAR Time 11

Cable Velocity and Distance Velocity 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 VF or VP Beware of VF Uncertainty VoP or NVP 12

Impedance “Z” Z = 75 Ohms Z = 100 Ohms 13

Cable Impedance (Z) and Reflections Impedance 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 Open Zo=75  or 100  Z = ∞ Ω Z = 0  Zo=75  or 100  Short 14

Pulse TDR Longer and Longer Dead Zones 15

Step TDR = No Dead Zones – Any Range Fault readings in Ohms Step TDR 16

 ON cycle runs Self Test, Calibration, and Restores last use settings  Input Voltage Detect Warning (>1VAC pk-to-pk or 50VDC)  OFF cycle saves all settings  Battery Saver shuts down saves all settings Powering Up/Down  Input over-voltage protection up to 250 VAC or DC 18

Soft Reset & Hard Power Down Perform Soft Reset if: 1. TDR menu cursors are unresponsive 2. Measurement Screen disorganized 3. Other performance issues Perform a Hard Power Down if TDR will not turn off normally Press and hold for 10 seconds Then power on with a Soft Reset 19 Then “Default Settings” will flash in the splash screen and Measurement Screen will open to 0-1KΩ Z Scale Then 1 Sec Press & Hold2 Sec Release

Cables Menu Compute a cable’s VF by testing a sample of known length – guided process Find a cable’s VF from known points – guided process 30

Minimum 10 ft or 2m Maximum 20Kft or 5Km Increase/decrease display range 31

Zoom Limits: Minimum 10ft (2m) to Maximum Set Range Zooms on active cursor 32

Scales: 20, 50, 100, 200, 500, & 1KΩ On lower Scale settings cable Z 0 will stay centered 33

Single active cursor has LED lit Rules when both cursors are on screen: 1. Both LEDs are lit 2. Last cursor key touched is active 3. Last cursor key touched appears on LCD with differential readings to other cursor’s – distance and Ohms 34

Tones generated on coax or selected twisted pair Most standard inductive amplifiers (probes) will pick up the tones TDR trace is not available while toning the cable. Battery Saver is suspended INPUT CHANNEL: Press for a menu of Tones 35 Use on Battery power only

E20/20 TDR Advanced Features MICRO FAULT – Locate minute defects in coax TEST LEAD NULL – Remove unknown test lead length from measurement VELOCITY 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. 36

Micro Fault ► MICRO FAULT – KINKS ONLY 37 For small kinks and crushes in coax cables TDR’s normal display will shift to an amplified reflection display with Z 0 as base line. In this example a fault barely seen in the normal impedance display shows up clearly.

Micro Fault ► MICRO FAULT – ALL FAULTS 38 Mainly for coax or high quality twisted pairs TDR’s normal display will shift to an amplified reflection Display Z 0 centered, no dribble-up & reduced Z Scale. In this example a fault barely Seen in the normal impedance display shows up clearly.

Test Lead Null Use a cursor to mark the End of the test lead and Press to set the length 39

Velocity Search When to use – If you have an installed cable with known lengths either to the end or an event on the cable. E20/20 will compute the cable’s VF based on marking the distance with a cursor, then use the to adjust the cable end or event to that distance. Press when end of cable and cursor are aligned to use the modified VF and return to Measurement Screen 40

Sample a Cable When to use – If you have a cable sample 10-50ft (3-15m) with an accurately measured length, and plan to install or test cable’s from it’s same reel or box. 41 Mark the end of the sample. Press and enter ft then in. Press TDR computes VF

Premises Advantage of a TDR? Quickly locate the distance to a fault and see type of fault Stop rewiring premise twisted pairs when a simple 5 minute fix will clear the trouble 95% of all premise telco wiring problems are in the jacks 1. Customer pulled out jack and broke a wire 2. Customer rewired jack and disrupted service 3. Bent or broken pins 4. Cat marked territory and corroded jack pins 49

OSP Testing and Fault Locating  Example Range Resolutions: 10ft=0.5inch, 500ft=2ft, 2000ft=8ft Use “Zoom” to improve horizontal resolution at cursor Use “Z Scale” to increase vertical resolution – Minimum +10 Ohms  Measure Cable’s Impedance (Z) & Resistance (Ω) “Dribble Up”  Use Noise Filter to clear the trace from noise. Yes! Detects Noise  Locates Distance and Impedance effects for: Poor SplicesBad Connections Series ResistanceCable Damage Wet CableLoad Coils Impedance MismatchesLossy Cable  Ranges: 0-10ft to 0-20Kft 50

Water in OSP Cabling Water Rules 1.Reduces the resistance of the wire’s insulation - Hence reduces cable’s Z. 2.Reduces velocity to an unknown – Distances in a water slug or after the slug are NOT valid ft 464 ft water 599 ft 311 ft 51 Wet Cable Only trusted distance is TDR to start of water

Cleaning Your 20/20 TDR 1. Always spray cleaners and rinse water on a soft cloth, do NOT spray directly on the TDR Soft Cases The soft case should be cleaned the same as the instrument. Use a soft bush to remove tough dirt. Do NOT immerse in water or dry in a dryer. Wash and Dry separately, both instrument and case should be 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 clean 3. Cable Gel – User liquid “citrus” cleaner to remove 4.Tar, creosote or adhesives – Use WD40 ® followed with mild detergent and water 62
