Narda EHP-50C Electric and Magnetic Field Analyzer | 5 Hz - 100 kHz
Discontinued
The Narda EHP-50C Electric and Magnetic Field Analyzer has been discontinued.
The Narda EHP-50C is a new and innovative system that has been designed to offer the highest performance, capabilities and functions, for measurements of low frequency electric and magnetic fields by Narda STS. The EHP-50C performs E and ß field measurements in the 5 Hz to 100 kHz range with an unsurpassed dynamic range of > 140 dB and built-in spectrum analyzer function. The EHP-50C, along with a display device (PC or Pocket PC), allows the user to select among three measurement modes: Wideband, which measures the contribution of all the frequency components in the selected frequency span; Highest, which measures only the highest level found within the Span; and Spectrum, with marker functions.Measurements of ELF/VLF (Extremely Low Frequency and Very Low Frequency) fields, in an accurate and repeatable manner, have long been a difficult proposition. Interference caused by the proximity of the surveyor has made E-field measurements especially difficult, and most devices have offered only single axis sensors rather than isotropic arrays that only served to further reduce repeatability. With new standards and recommendations (like IEEE C95.6) being introduced and the increase of implanted medical devices, analysis tools like the Narda EHP-50C are more essential than ever.
