Description
EMC1150 Low Noise Preamplifier for EMI Testing
The EMC1150 Low Noise Preamplifier is a high-performance solution designed for electromagnetic interference (EMI) testing and compliance measurements. Covering a broad frequency range from 9 kHz to 1 GHz, this preamplifier provides a powerful 50 dB minimum gain while maintaining an exceptionally low noise figure of 1.8 dB typical. This combination makes it a reliable choice for test engineers who demand precision, accuracy, and repeatability.
Engineered with state-of-the-art technology, the EMC1150 is ideal for applications across diverse markets such as automotive, avionics, industrial, medical electronics, RF, wireless/telecom, and military testing. It fully supports leading test standards, including ANSI C63.4, ANSI C63.5, CISPR 12, CISPR 16-1-4, CISPR 22, CISPR 25, CISPR 32, FMC1278, GM W 3097, and MIL-STD-461.
One of the most significant advantages of the EMC1150 is its ability to compensate for long cable loss during EMI measurements, ensuring higher accuracy and system stability. Its high linearity LNA design provides excellent dynamic range, making it suitable for challenging EMI test environments. Additionally, the unit’s unconditional stability guarantees dependable results across its full operating range.
The EMC1150 is designed for ease of integration into test setups, featuring 50-ohm Type N female connectors, built-in AC input power supply (110/230 Vac), and a grounding detect circuit for safe and reliable operation. Compact in size (217 x 254 x 100 mm) and weighing just 2.8 kg, it is lightweight and convenient for benchtop or rack use. For added protection, an optional pulse/ESD protector can be included.
Whether for compliance testing, R&D, or production environments, the EMC1150 ensures superior EMI measurement performance with improved system noise floor flatness and long-term reliability.
