| Haefely PEFT-Junior Burst Tester
The Haefely PEFT Junior 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 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.
Further user benefits with PATS operation
include:
-
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
