The PMM Narda EHP-50C is a low frequency electric and magnetic isotropic field probe-analyzer, providing an advanced technology solution for field measurements from a few V/m (or nT) to thousands V/m (or mT), in the 5 Hz to 100 kHz range including X, Y and Z axes measurements with a powerful spectrum analyzer built in.
The Narda EHP-50C can be used connected with 8053-DISPLAY, SB04 and PC. EHP-50C has an additional mode of operation that allows it to be used in stand alone mode over 24 hours of continuous data collection. EHP-50C include an E2 PROM, that stores the calibration data, the frequency and level calibration tables, and an internal optical repeater that allows the connection to external devices. The spectral analysis of the signals, obtained through a powerful DSP (Digital Signal Processor), is performed on seven different Span values and is displayed on the PC monitor or 8053-Display . By using a Marker it is possible to obtain the precise measurement of the frequencies and levels. EHP-50C is managed internally with a microprocessor (CPU module) that controls all its main functions, from the charging of the batteries to the serial communication with the DSP unit. The Electric or Magnetic field is picked up by the three sensors on the X, Y and Z axes. A Digital/Analog conversion follows which transforms the signal into numeric information processed by a Digital Signal Processing unit.
