ELQ-2+ 2.2MHz xDSL Line Qualifier
- The ELQ-2+ is a 2.2 MHz tester for the qualification of ADSL2 +, ADSL, READSL2, ADSL G LITE, ADSL G.LITE2, SHDSL, HDSL, ISDN and VF lines with pre-programmed templates and data transfer speed calculation
- It also incorporates a TDR function for locating cable faults such as loose contacts or splits causing crosstalk
- An optional active AC-DC bridge is available for accurate fault location
- Two testers are required for end-to-end measurement. The testers communicate over the line allowing an instrument configured as master to remotely control another configured as slave
- Tolerance masks of cable parameters such as loss, LCL, return loss, impedance and the principal system parameters are pre-programmed for several xDSL systems
- The automatic test sequence provides pass/fail indication by comparing the test results against the tolerance masks and the calculated achievable rate against the required data rate
- Single sided measurements include transmitter, receiver, spectrum analyzer, wide band noise, impulsive noise, return loss, impedance, NEXT(Loss) balance measurements and load coil detection
- It has a built-in service telephone function with microphone and speaker
- Software options include:
- Micro-interruption measurement according to ITU O.62 divided into categories with duration and distribution
- Exchange side electrical length (ESEL) measurement up to 120dB
- ESEL dependent templates for achievable rate calculation for the local subscriber lines when the local DSLAM is working with reduced transmit power (DPBO is applied)
- Software for user defined test parameter editing on a PC
- Supplied in a soft case with a battery, charger, USB stick, USB cable and software for results transfer to a PC
