  1. Trouble Shooting with ELQ 30A Typical Cable Problems NEXT Measurement FEXT Measurement Location of XTALK Point Recognition of Bridged Taps Location of Bridged Taps Micro Interruption Detection Location of Loose Contacts LCL Balance Measurement To learn more click onthe selectedtopic! ELEKTR NIKA

  2. Near End Crosstalk Measurement with ELQ 30A The location of cross talk point can be found by the TDR of ELQ 30A To visit the TDR page click on the key ELEKTR NIKA

  3. Far End Crosstalk Measurement with ELQ 30A The location of cross talk point can be found by the TDR of ELQ 30A To visit the TDR page click on the key ELEKTR NIKA

  4. Crosstalk Point Location with the TDR of ELQ 30A When the XTALK is out of limit it is very likely that the reason is split.The best tool to locate the XTALK points is ELQ 30A in TDRXTALK mode. ELQ 30A Split Resplit Typical Waveform ELEKTR NIKA

  5. Recognition of Bridged Taps Impedance measurementisthe best tool to recognize bridged taps because they cause strongly wavingline impedance Typical impedance measurement result The location of bridged tap can be found by the TDR of ELQ30A To visit the TDR page click on the key ELEKTR NIKA

  6. Bridged Tap Locationwith the TDR of ELQ 30A When the line impedance is strongly waving it is very likely that the reason is bridged tap. The best tool to locate it the TDR of ELQ 30A Typical Waveform Distance to tap Length of tap ELEKTR NIKA

  7. Micro Interruption Detection Micro interruption is a temporary line interruption due to loose contacts.ELQ 30A detects the micro interruptions using 1020 Hz test tone The location of loose contact can be found by long time TDR measurement To visit the TDR page click on the key ELEKTR NIKA

  8. Loose Contact Location ELQ 30A in long time TDR mode performs a sequence of repeated measurementsThe obtained waveforms are different if the features of tested pair change during the test Typical Waveform ELEKTR NIKA

  9. Balance (LCL ) Measurement ELQ 30A in Master-Slave mode provides a useful tool to findunbalance causing impairment of xDSL connections. ELEKTR NIKA
