Haefely PEFT Junior Burst Tester
The Haefely PEFT Junior Burst Tester serves to perform electromagnetic immunity tests on electronic appliances and systems with nanosecond spikes (Bursts). The Haefely PEFT Junior Tester exceed the requirements of IEC 801-4 and IEC 1000-4-4.
The Haefely PEFT Junior ideally complements the well known modular and flexible Haefely FEET Tester for applications in design labs with test voltages up to 4 kV. The Haefely PEFT Junior excels by its light weight, its compact design, its integrated printer interface for test report generation and its optimized price/performance relation.
The Haefely PEFT Junior Burst Tester enhances the quality and reduces the development time of your products by testing closer to reality. Spike frequencies up to 1 MHz with even or random distribution and Ohmic load independent wave shape.
The PEFT Junior con be operated stand alone or integrated in the PATS automatic Test System; the Win PATS Software runs under Windows 3.1.
Features
- EUT surveillance (failure detection)
- Automatic test report generation
- Automatic output performance verification of the PEFT Junior in accordance with the provisions of the IEC Standard
