Applications

ELQ 30 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 with end-to-end measurements, two instruments can be used in MASTER-SLAVE mode. Just one person, thanks to the communication between the two instruments, can perform the measurement tasks. Operation is made extremely simple with pre-defined automatic test sequences.

Tolerance masks of cable parameters as Loss, LCL, Return Loss, Impedance, and the principal sys-tem parameters are pre-programmed for several VDSL systems.

New user defined template sets can be created with the parameter editor of ELQ 30 without PC. (PC program is also available.)

The automatic test sequence of the ELQ 30 provides an immediate PASS/FAIL indication by com-paring the test results with the tolerance masks and the required data rate with the calcu-lated theoretically achievable bit rate.

Detailed test results are available in graphic and numeric forms. In case of FAIL indication the rea-son of failure is indicated with asterisks.

• Physical parameter measurements to pre-qualify copper wire pairs for high bit rate VDSL services before the installation of modems• Automatic test sequences with preprogrammed or user defined test parameter sets

belonging to different VDSL systems• Bit rate calculation for each VDSL system• PASS/FAIL indication
