The xDSL LINE QUALIFIER ELQ 2+ is a hand held battery operated, multifunction measuring instrument, intended for pre-qualification, installation, fault location and maintenance of balanced copper pairs. To qualify a pair, end-to-end measurements with two instruments have to be used in MASTER-SLAVE arrangement. Just one person, thanks to the communication between the two instruments, can perform such measurements. Operation is made extremely simple by means of pre-defined automatic test sequences. ELQ 2+ can be programmed as MASTER and SLAVE as well. Tolerance masks of cable parameters as Loss, LCL, NEXT, FEXT, Impedance, Return Loss and the principal system parameters are preprogrammed for more than 50 different xDSL systems. The operator can create new template sets with the PARAMETER EDITOR facility of ELQ 2+ on the spot. Template sets can be downloaded from PC as well. When the automatic test sequence is ready ELQ 2+ provides an immediate PASS/FAIL indication by comparing the test results with the tolerance masks and the required data rate with the calculated theoretically achievable rate. Detailed test results are available in graphic and numeric forms. In case of FAIL indication the reason of failure is marked with asterisks. For fault location DC-AC bridge, TDR and basic cable parameter measurements are provided.
