ELQ 30 is a hand held battery operated, multifunction measuring instrument, intended for pre-qualification, installation, fault location and maintenance of balanced copper pairs

Pre-qualification in Master Slave mode Just one person, thanks to the communication between the two instruments, can perform such measurements. Operation is made extremely simple by means of predefined automatic test sequences. ELQ 30 can be programmed as MASTER and SLAVE as well.

Pre-programmed Tolerance Masks Tolerance masks of cable parameters as Loss, LCL, Return Loss, Impedance, and the principal system parameters are pre-programmed for several ADSL and VDSL systems. User defined template sets can be created with the parameter editor of ELQ 30 without PC.

Automatic Data Rate Calculation

Immediate PASS/FAIL indication When the automatic test sequence is ready ELQ 30 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. The test results can be stored in memory and transferred to PC.

Features:

  ■ Pre-qualification of copper wire pairs with physical parameter measurements up to 35 MHz

     before installation of Vplus, VDSL, ADSL 2+, ADSL, SHDSL or other modems

  ■ Line qualification with immediate PASS/FAIL indication

  ■ Automatic (master-slave) test sequences

  ■ Achievable data rate prediction

  ■ Preprogrammed tolerance masks

  ■ Analogue measurements on leased or switched circuits 20 Hz to 20 kHz

  ■ Analogue-to-analogue measurements on PCM systems

  ■ Loop holding and dialling (pulse or DTMF) for dial-up circuit testing

  ■ Built-in loudspeaker and microphone, service telephone

  ■ In-service talk/listen and voice monitoring facility

  ■ Test of ordinary or special quality circuits
