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:
