Coupling Adapter Model CA-803A

The generated pulses are coupled to the EUT power lines through the injection circuit integrated with the INS simulator.  For coupling to all other external interface cables such as communication, signal, I/O, control, this optional item is a must.  As an inductive coupling adapter, which is based on the transformer principle, the circuit in the coupling adaptor works as the primary winding and the cables under test which are surrounded by the adaptor work as the secondary. 

  • The user does not need to cut the cable to inject noises to the signal, DC, AC or Ground line of the equipment under test.
  • The user can perform a test for the immunity level of the each part, block, unit or component composing the equipment under test.
  • Direct noise injection into the signal line enabling effective checking of the level of noise immunity.
  • The cable to be tested of up to 15mm in diameter can be put through the CA-803.


  • Input voltage: 2000V max.
  • Input pulse width: 50ns - 1μs
  • Coupling ratio: 1/20 
  • Dimensions: (W)160 x (H) 60 x (D) 35 mm
  • Weight: Approx. 400g


  • CA-803 main unit (1 pc).
  • Connecting cable 1M NMHV(P)-NMHV(P) (1 pc.)
  • Instruction manual (1 pc.) 


NOTICE: When the CA-803A is used with the INS-410, INS-420, INS-420A or INS-4400 series Simulator, an optional conversion cable is required.
