BCI Testing (Bulk Current Injection)
stable output power across wide impedance ranges
Bulk Current Injection (BCI) testing is used to evaluate the susceptibility of electronic systems to conducted electromagnetic interference (EMI) coupled onto cables and wiring harnesses. Current is directly injected into cables to simulate interference encountered on power and communication lines in real-world operating environments.
This method is widely applied across automotive, aerospace, defense, and industrial sectors, where cable coupling is a dominant interference mechanism. BCI enables engineers to assess system-level robustness by exposing the device under test (DUT) to controlled disturbance signals while monitoring functional performance.
A key challenge in BCI testing is the wide variation in impedance presented by real-world harnesses and loads. As a result, maintaining consistent current levels and test repeatability requires amplifiers capable of stable operation across highly mismatched conditions.
Amplifiers for BCI Testing
AR amplifiers for BCI applications are designed to deliver stable output power across wide impedance ranges, ensuring consistent current injection into non‑50 Ω loads. High ruggedness, mismatch tolerance, and linearity are critical characteristics.
These amplifiers support CW operation with reliable performance in demanding test setups, and can be integrated into complete BCI systems including injection probes, monitoring equipment, and control software.
Typical requirements:
- 10 kHz to 400 MHz
- CW power up to 1 kW
High power RF and microwave amplifiers supporting broadband, narrowband, solid state, and TWT applications.
Integrated RF test systems combining amplification, control, and measurement for application specific test environments.
High performance antennas supporting EMC, immunity, and wireless testing across wide frequency and power ranges.
Control and automation software enabling efficient test execution, data acquisition, and standards based compliance workflows.
Precision field probes for accurate electric and magnetic field measurement during EMC and immunity testing.
RF test accessories including couplers, loads, switches, and cabling to complete and extend system capability.
