TH7012 – CAN FD/LIN disturbance interface

LIN Interference Mode:

When configured with the PC software in LIN interference mode, TH7012 supports:

• Interfering with specific bits of a LIN frame
• Flipping specific bits of a LIN frame
• Interference count statistics
• Sampling point testing
• Sending incomplete frame headers based on user configuration, where the header can include:
  • Sync break only
  • Sync break + sync field
  • Sync break + sync field + protected ID field
• Configurable data segments and inter-byte intervals in frame responses
• ±14% offset in transmit baud rate
• Bit-time measurement
• Trigger output for LIN frame interference

CAN (FD) Interference Mode:

When configured in CAN (FD) interference mode, TH7012 supports:

• Interfering with specific bits of CAN (FD) frames
• Configurable interference lengths
• Multiple trigger modes, including frame trigger, error trigger, and software trigger
• Bit-timing deviation testing
• Bus-off behavior testing
• Sampling point testing

ISO 16845 Testing Mode:

When configured in ISO 16845 testing mode, TH7012 can verify the IUT’s (Implementation Under Test) handling of:

• Standard frames, extended frames, CAN FD frames, and CAN FD extended frames with various identifiers and lengths
• Error handling, including bit errors, CRC errors, stuffing errors, format errors, and overload frames
• Behavior in active and passive error states

TH7012 is designed for CAN (FD)/LIN protocol testing, ensuring that nodes comply with communication protocol specifications and guaranteeing safe and reliable network operation. It can also be used to verify whether the IUT’s CAN IP core complies with the ISO-11898-1 CAN communication protocol standard.
