ATEC offers affordable rental rates for ISO 7637 transient generators and carries a broad inventory of automotive transient test systems and automotive EMC test equipment.
What is an Automotive Transient Generator?
An automotive transient generator is designed for testing automotive components for their susceptibility to automotive EMI, surges, or drops in current. These problems can possibly shut off or damage electrical components built into the car. Automotive component transient immunity is primarily regulated by the test standard ISO 7637. The advancement of technology in the automotive industry has led to higher quality, more complex electrical systems integrated into cars, which rely on successful communication between sensors and control systems. New electrical components are new potential victims of automotive EMI, meaning the conducted immunity testing of cars is becoming a more and more complex process.
Testing with an ISO 7637 transient generator
An ISO 7637 transient generator simplifies the process of automotive EMC testing. Automotive transient immunity generators are specifically designed to produce waveforms that simulate real-world car troubles. Cranking the ignition is a source of surges which overload components like the stereo, turn signals, or even the battery and alternator. Another source is referred to as a load dump—the battery disconnects in the middle of being charged by the alternator, and the car dies. A variety of immunity tests are conducted to reproduce these conditions.
What is EMC Testing?
EMC testing is a process in which test engineers look for disruptive electromagnetic energy and make sure devices do not accidentally emit RF signals. An ISO 7637 transient generator simplifies the EMC testing process and allows technicians to detect system problems efficiently and accurately within a vehicle. This advantage will ultimately save time and money.
How Does an ISO 7637 Transient Generator work?
ISO 7637 test equipment uses voltage and current during the testing process. The device produces waveforms that simulate real-world car problems. Technicians can change variables on the ISO 7637 transient generator, using the unit’s interface, to run specific tests, including load dump testing, voltage drop testing, and more. Test engineers look to international standards organization (ISO) and original equipment manufacturer (OEM) test standards for guidance in achieving automotive EMC compliance.
