Ultra WideBand test setup
IEC 61000-4-36 UWB

UWB refers to a high power electromagnetic (HPEM) threat for electronic and computer systems. Standardisation bodies such as IEC Study Group 77c are working on threat classification and test procedure definitions.

The test setup consists of a fast pulse generator connected to a HIRA (Half Impulse Radiating Antenna). The HIRA has the ability to radiate a narrow beam of pulsed electromagnetic energy over a large bandwidth. This antenna can also be used for continuous wave signals. Electronic equipment immunity assessment is the main application of this test setup.

Advantages

  • Transportable test system for onsite testing possibilities
  • Parabolic antenna with adjustable horizontal and vertical tilt
  • Measurement sensors adapted to the test system
