Acrobat Reader needed
 FIVE INSTRUMENTS IN ONE
  • 30 MHz test set for ADSL, VDSL line qualification with  data transfer speed calculation
  • 20Hz to 20 kHz test set for the test of voice frequency circuits
  • Active AC-DC bridge for accurate and comfortable fault location
  • Digital Multimeter
  • TDR to find low impedance faults and splits causing cross talk between the pairs

    • SINGLE END MEASUREMENTS  up to 30 MHz (with one instrument)
  • Return loss, LCL, NEXT, Impedance, Noise, Spectrum analyser, Impulse noise
  • Fault location with TDR

    • END TO END MEASUREMENTS up to 30 MHz (with two instruments)
  • Automatic (master-slave) test sequences
  • Preprogrammed & user editable tolerance masks
  • Line qualification with immediate PASS/FAIL indication

    • AC-DC FAULT LOCATION
  • Resistance Measurements:  Loop resistance,  Resistance difference,  Insulation resistance
  • Capacitance Measurements:  Cable capacitance, · Capacitive balance
  • DC Fault Location Methods:  Murray,  Küpfmüller,  Repeated Küpfmüller
  • AC Fault Location Methods:  Interruption,  Repeated Küpfmüller
  • TDR Measurements:  Single pair,  Long time,  XTALK,  Comparison to Memory

    • DMM MEASUREMENTS
