Automotive interface & communications HIL tester

Block diagram

Overview

Our integrated circuits and reference designs help create high-precision automotive interface communications hardware in loop (HIL) tester for accurate testing of all automotive subsystems during manufacturing and service of the vehicle.

Design requirements

New generation automotive interface and communications HIL tester designs require:

  • High-speed transmit and receive signal chain solutions for automotive radar and wireless communication testing.
  • High-voltage and current-source measurement units for electric vehicle (EV) drivetrain systems.
  • High-speed protocol analyzers for serial bus testing.
  • High-precision spectrum analyzers for EMI/EMC compliance testing.
