the HM130 VHF Radio.
The test simulates a slow, high-energy pulse produced by an NLS event.Relative external document as below

Safety
The high voltage interference pulse can contain a very large quantity of energy and every precaution shall be
taken to avoid contact with EUT during a test. It is highly recommended that at least one other person is
present (or very close by) during the test.
Test Configuration
EUT Setup
The EUT shall be setup in a typical system configuration on an isolated wooden bench with NO
GROUNDPLANE. The power to the EUT and auxiliary equipment shall be from 12V or 24V sealed lead-acid
batteries via a suitable fuse. The length of the EUT power cable shall be no more than 2m. Any screens within
the system shall be terminated at the battery –vet connection.
