| 仪器介绍 |
| PMM's new E-H fields analyzer model EHP200 has been designed for accurate, stand-alone and PC-based measurements of both electric (0,02 to 1000 V/m) and magnetic (6 mA/m to 300 A/m) fields, in the 9 kHz - 30 MHz frequency range. The robust housing sized only 96 x 96 x 115 mm holds both field sensors and electronic measuring circuitry. Separate 3 axis and total values (peak and average) are measured with exceptional flatness and linearity of ±0,3 dB. Results are expressed in V/m, A/m, μT, mW/cm2, W/m2. The EHP200 features built-in spectrum analysis with maximum IF resolution of 1 kHz for detailed measurements of E and H field intensity vs. frequency with dynamic range of 80 dB. Power supply by internal rechargeable Li-Ion battery of up to 8 hours of continuous operation, or from external 10 ÷ 15 VDC source. AC adapter provided. The EHP200 is controlled by the PMM’s PC program, and measurements are sent in real time through the optical fiber link. An auxiliary input allows for measuring the frequency spectrum of external signals from any other RF device. Thanks to its very small size and optical fiber link, the EHP200 does not influence the electromagnetic fields to measure, thus ensuring more accurate and sensitive measurements. The EHP200 is particularly suitable for nearby measurements of LW-AM-SW transmitters, metal detectors, and any other measurements of RF signal in the 9 kHz - 30 MHz range, with great advantages wherever the conventional antennas are inadequate due to their physical dimensions and cable influence. |
