1 m EUT Test System

Part Number: RS105-1

The APELC RS-105 test system utilizes APELC’s compact Marx Generator technology to generate a pulse in accordance with MIL-STD 461G, test procedure RS-105. Test volume dimensions can accommodate a 2m X 2m X 1m (L X W X H) EUT in accordance with the MIL-STD.

The pulse propagates from the source (Marx Generator), down a tapered transmission line, and into the test-volume, allowing electronic equipment under test (EUT) to be subjected to field strengths as high as 55 kV/m and as low as 5 kV/m, in the form of a 1.8-2.8 ns rise-time, 23 (+/- 5) ns pulse-width transient.

Able to be controlled locally or via computer, the system includes a power and control rack, complete with positive and negative high-voltage power supplies, high-voltage trigger unit, 2-channel gas control panel, and control.

The system’s control and data acquisition option allows users to enter a desired field strength. The software then calculates and sets the required charge voltage and air-pressure for the Marx and peaking circuits. The software automatically acquires the reference and EUT waveforms from the oscilloscope, scales them based upon calibration factors/attenuation, and displays them along with peak field/voltage, rise-time, and FWHM. Test reports are at the push of a button.


Constructed from durable, weather-resistant fiberglass and stainless-steel aircraft cable, the collapsible version system can be assembled in as little as one day.

Please exercise caution when operating near electronic equipment other than the EUT. Unhardened electronics can be harmed by the EMP generated by the RS-105 test system. Take precautions to isolate or protect sensitive electronics from exposure to high-EMI environments. It is not recommended to take personal electronics devices such as phones near the system when in use.

Persons with personal electronics or medical devices should not operate the Vertical EMP Simulator, nor should they be proximate to the operation of this system.
