Descriere

ELA 10 DATA LINE ANALYSER is a flexible and highly functional hand held instrument for analog testing in the range 20 Hz to 20 (85) kHz. Digital signal processing (DSP) technology delivers fast accurate results in a compact battery powered instrument ideal for field use. It is intended for the test of 2/4 W ordinary or special quality leased circuits and dial-up circuits. ELA 10 provides single sided and end-to-end measurements with two instruments in MASTERSLAVE arrangement. Just one person, thanks to the communication between the two instruments, can perform such measurements. Operation is made extremely simple by means of pre-defined automatic test sequences. ELA 10 can be programmed as MASTER and SLAVE as well. Tolerance masks of cable parameters and the principal system parameters are pre-programmed for ITU-T M.1020, M.1025 and M.1040 systems. When the automatic test sequence is ready ELA 10 provides an immediate PASS/FAIL indication by comparing the test results with the tolerance masks. Detailed test results are available in graphic and numeric forms. In case of FAIL indication the reason of failure is marked with asterisks. The test results can be stored in memory and transferred to PC for post processing or creating archive.
