Powering ON

Pressing ON starts the unit,

performs a self-check

and restores the last used settings

Powering ON with Soft Reset

Press ON and then quickly

pressing ENTER 4 – 5 times

performs a soft reset and restores

factory default settings

slide9

HIGH VOLTAGE DETECTED

Try pressing ENTER 1 or 2 times to see if the detection clears

If it will not clear, there is more than 100 VDC or 0.5VAC on

the line being tested. Use precautions to remove the TDR and

remove or reduce the voltage prior to retesting.

The 20/20 TDR is protected to 300VAC and 300VDC

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

Example: .66c

Z = 100 Ohms

Z = 75 Ohms

Z = ∞Ω

Zo=75 or 100

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

Example 20/20 “Step” TDR Traces

Open Cable or Pair

Shorted Cable or Pair

Opens and shorts send the trace to maximum or zero Ohms respectively.

Unlike a pulse TDR, there is no trace after these events

24

slide26

Example 20/20 “Step” TDR Traces

Bad Connector on RG-59

Mixed Z, 75 then 50 Ohm

Both events will cause unwanted signal reflections.

The 50 Ohm cable will add extra signal attenuation

25

slide27

Example 20/20 “Step” TDR Traces

Good Splice

Poor Splice

These splices are in 100 Ohm twisted pair cable,

but will appear similar in coaxial cable

26

slide28

Example 20/20 “Step” TDR Traces

Wet Cable

Split and Resplit

Splits and resplits are common

in home wiring where the owner

didn’t understand the importance

of pairing

Wet cable always show an

erratic downward

excursion on the trace.

  • The 20/20 TDR menu simplifies looking at any single pair

or the difference between any two pairs

  • The 20/20 TDR is impedance independent and can test both

coax and twisted pair cables with the same TDR

  • The 20/20 TDR has a customized cable list for CATV techs

that covers OSP coax, Premise coax and twisted pairs for

Premise 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

OSP Testing and Fault Locating

  • Range Maximums: velocity dependent – 6,600 ft @ .66c

8,800 ft @ .88c

  • Measure Cable’s Impedance (Z) & Resistance (Ω) via “Dribble Up”
  • Use Noise, Averaging or Video Filters to clear the trace
  • Locates Distance and Impedance effects for:

Poor Splices Bad Connections

Cable Kinks Cable Damage

Water & wet taps Network Devices

Impedance Mismatches Lossy Cable

20/20 TDR’s Advanced Features

Differential Mode ------------ Compares one twisted pair to another

twisted pair and shows any differences

Intermittent Grabber --------- Permits looking for a short or open

and moving the cable or connectors

to find an intermittent fault

Fault Finder ------------------- Set upper and lower impedance limits,

the TDR will jump the cursor to the

first point exceeding the limit.

SWR Mode ------------------ Provides calculated Standing Wave

Ratio of the cable along it’s length

Return Amplitude ---------- Provides calculated Return Amplitude

in dB for mismatch events

44

slide46

3. Press and select INPUT CHANNEL

4.Press any key as required to select RJ45 AΔB for telco leads

difference or any other RJ45 xΔx as desired, see QRG table

Using Differential Mode

1.Measure a single pair in a cable and and note the events

  • Connect the telco test leads’ Green/Black pair or use an RJ45
  • plug input for access to another of the four pairs

5. Press ENTER

45

slide47

2. Press select INTRMTENT GRAB and press any

key to turn ON

Intermittent Grabber Mode

1. Connect the cable with the suspect intermittent fault and full trace

3. Hand-over-hand move along the cable flexing and moving

sections and connection points to induce the fault

NOTE: If the entire trace goes erratic, change the termination & try again.

The fault and the cable’s termination must match for a correct display.

arrows or direct mouse pointer on

the cursor line. The DELTA

reading is the difference between

the two cursors.

Cleaning Your 20/20 TDR

1. Always spray cleaners and rinse water on a soft cloth, do NOT

spray directly on the TDR

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

  • Tar, creosote or adhesives – Use WD40® followed with mild
  • detergent and water

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.
