Automatic Single Sided Test Sequence of ELQ 30A

To learn more click on the selected topic!

ELQ 30A provides single sided test sequences to estimate the data transfer capacity of the tested lines used for different xDSL systems without the aid of far end device or a second operator.

Numerous test parameter sets are pre-programmed containing: ■ Tolerance masks for Loss, LCL, Return Loss, Impedance measurement ■ Principal system parameters for VDSL2, VDSL1, ADSL2 +, ADSL, ADSL G LITE READSL2, ADSL G LITE, ADSL G.LITE2, SHDSL, HDSL, ISDN systems.

Using the pre-programmed test parameters ELQ 30A provides immediate PASS/FAIL qualification and detailed information about the reasons of failure.

After selecting the cable type and xDSL system ELQ 30A launches an automatic test sequence performing unilateral measurements
