The ELQ2-DT xDSL Line Qualifier is a handheld, battery-operated, multi-function measuring instrument intended for the prequalification, installation, and maintenance of balanced copper pairs.

Highlights

Copper cable qualifying for xDSL systems regarding ITU-T and ETSI recommendations, including DMM measurements, impedance, return loss, LCL, and NEXT measurements up to 2.1 MHz in one device.

Applications

Basic cable tests.

Advanced cable qualification.

Automatic measurements.

Key Features

Physical parameter measurements on balanced subscriber access lines for ADSL, HDSL, ISDN, and PCM.

Single-end measurements, including spectrum analyzer; impedance, return loss, LCL and NEXT measurements up to 2.1 MHz; noise and impulse noise measurements; and AC/DC voltage measurements.

End-to-end measurements (using two ELQ2-DT), including measurement of all parameters up to 2.1 MHz for line qualification of subscriber access lines (loss, frequency response, and FEWXT) as well as master-slave mode by automatic communication between the two instruments.
