High-Field Immunity Testing Expansion at IBL-Lab

The investment supports testing according to key defense standards, including MIL-STD-461, AECTP-500, VG 95370 and VG 95373, addressing increasing requirements for realistic and high-intensity EMC immunity testing.

Extended Frequency Coverage and High Field Strengths

The integrated amplifier system from Rohde & Schwarz combines multiple frequency ranges into a single test environment. In the 6–18 GHz range, field strengths exceeding 400 V/m have already been achieved using the R&S BBA300-FG180 in a direct antenna mounting configuration, minimizing RF losses. Further expansion targets field strengths above 600 V/m.

Amplifier Setup Overview

The setup enables continuous high-field immunity testing across the full frequency range using multiple high-power amplifiers:

• BBL200A-A5000: 9 kHz–250 MHz, 5 kW continuous / 7.5 kW peak, water-cooled

• BBA150-BC2000: 80 MHz–1 GHz, 2 kW (optional 3 kW)

• BBA300-DE1000: 1–6 GHz, 1 kW

• BBA300-FG180: 6–18 GHz, 180 W / 300 W

This includes early adoption of the R&S BBA300-DE1000, positioning IBL-Lab among the first laboratories worldwide to deploy this amplifier.
