Datasheet

Narda EHP-200A electric and magnetic field analyzers perform both narrowband and wideband EMF measurements over a frequency range of 9 kHz to 30 MHz. The compact, lightweight EHP-200A is designed to provide both E-Field and H-Field testing capabilities in a small housing that allows for minimum field perturbation. The field meter measures electric fields ranging from 0.02 to 1000 V/m and magnetic fields from 0.6 mA/m to 300 A/m. Narda EHP-200A field analyzers measure both near and far fields, making them suitable for both occupational safety and signal analysis testing. Whether your application calls for determining the safety of industrial machinery, diagnosing emission levels around antenna arrays, testing antenna transmissions or delineating between the near and far fields, the EHP is the ideal test solution. The included PC program will also calculate field wave impedance for you, a useful feature for analyzing the scattered near field of large broadcasting antenna systems.
