Our CAN Disturbance Interface - Flexible & Compact

Precise and Reproducible Disturbances of CAN (FD) Networks

VH6501 is a flexible yet compact CAN (FD) disturbance hardware and a network interface for CANoe combined in one device.

In particular, the combination of disturbance hardware and network interface allows very simple test setups for CAN (FD) conformance tests without an additional network interface or a special cable.

Wiring options


  • Disturbance hardware and network interface combined in one compact USB device
  • Extensive trigger sources and disturbance types
  • Fine granular output of complex disturbances
  • External trigger output
  • Seamless CANoe integration
  • CAPL functions for test automation
  • Analog/digital I/O functionality
  • Connection for external time synchronization

Application Areas

VH6501 enables you to generate disturbances of almost any kind precisely and reproducibly in CAN (FD) networks. This makes it the ideal tool for testing the fault handling of CAN (FD) nodes. Such tests are an essential part of conformance tests on a physical level, for example the software tool CANoe Test Package VAG is used for.


Digital disturbances

  • Arbitrary sequences of dominant and recessive levels (including recessive stress)
  • Max. 4,096 level change in a sequence
  • Support for different trigger conditions:

    • I/O triggers

    • Frame triggers, e.g. SOF, Frame, Bus Idle, Error

    • Combined frame triggers for disturbing e.g. different IDs (up to 32 parallel conditions including wildcards)

Analog disturbances

  • Asynchronous, without own trigger condition
  • Support for different error and test modes:

    • Short-circuit tests

    • Cross-wiring

    • Modification of the R and C network parameters:

      • R: 500 Ω...25 kΩ (non-linear)

      • C: 100 pf...10 nF (non-linear)
