Databus Network Analyser

Databus Network Analyser

The S2476N databus network tester isolates all common wiring faults on any platform with a 1553 databus harness system: short circuits, shorts to shield, open circuits and cross-overs etc. It measures insertion loss between any two stubs in dBs. It is simple to operate, with no need to disconnect the main bus and comes with an integral battery charger; ideal for one-man operation.

The kit comprises aircraft specific interconnect leads to connect the tester to the aircraft of choice, consumable spares for the tester, a databus repair kit, full technical publications and a transit case. Additional options include a calibration kit and an ARINC 429 protocol tester (DE3400).

Key information

S2476N can detect:

  • Short circuits between twisted pairs of bus or stub
  • Open circuits on bus or stub
  • Cross-overs of twisted pairs, on bus or stub
  • Short circuits between either of the wires of the bus or stub twisted pair to shield/screen system
  • Insertion loss between any two stubs in decibels in the range 0dB¬† to -36dBs (+/- 0.1dB)
