Anritsu ML428B Interference/Field Strength Meter, 9 kHz – 30MHz

Anritsu ML428B Interference/Field Strength Meter, 9 kHz – 30MHz,This wideband interference and field strength meter is designed to evaluate signal levels and electromagnetic interference (EMI) in the 9 kHz to 30 MHz frequency range. It offers high sensitivity and dynamic range, making it suitable for compliance testing, interference diagnostics, and signal surveillance. The ML428B can measure field strength with connected antennas and also supports direct input signal analysis. Its analog and digital filtering capabilities allow fine control over bandwidth, enhancing the accuracy of narrowband and wideband measurements. With a built-in speaker and audio output, users can monitor modulation types and distinguish signal types during measurement. The robust design includes a large, easy-to-read display and user-friendly controls, enabling efficient use in field environments. It’s widely used in spectrum monitoring, EMI test labs, and regulatory field enforcement operations to detect unauthorized transmissions or verify compliance with emission standards.
