xIn case of devices permanently connected to the power supply, and lacking any fuses or other

devices of mains protection, the power line must be equipped with adequate protection

commensurate to the consumption of all the devices connected to it;

xDevices in Safety Class I, equipped with connection to the power mains by means of cord and plug,

can only be plugged into a socket equipped with a ground wire;

xAny interruption or loosening of the ground wire or of a connecting power cable, inside or outside the

device, will cause a potential risk for the safety of the personnel;

xGround connections must not be interrupted;

xTo prevent the possible danger of electrocution, do not remove any covers, panels or guards installed

on the device, and refer only to NARDA Service Centers if maintenance should be necessary;

xTo maintain adequate protection from fire hazards, replace fuses only with others of the same type

and rating;

xFollow the safety regulations and any additional instructions in this manual to prevent accidents and

damages.

1 - General information

1.1 Documentation The following documents are included in this Manual:

xA questionnaire to be sent to NARDA together with the apparatus

should service be required.

xA checklist of the Accessories included in the shipment.

This Manual includes description of EHP-50F standard and optional

accessories.

1.2 Introduction This section provides a general overview of EHP-50F Electric and

Magnetic Field Analyzer.

EHP-50F is a low frequency electric and magnetic isotropic field probe-

analyzer. It provides an advanced technology solution for field analysis in

the 1 Hz to 400 kHz frequency range in an extremely high dynamic range.

It includes X, Y and Z axes simultaneous measurements with a powerful,

built in, spectrum analyzer.

EHP-50F can be used either connected to NBM-550 portable field meter

or PC. Additionally, stand alone operation mode is provided for up to 24

hours continuous data collection.

EHP-50F includes a non volatile memory which stores frequency and level

calibration tables and an internal optical repeater which allows connection

to external devices through the optical fibre.

Spectral analysis, obtained through DSP (Digital Signal Processor), is

performed on eight different frequency Span values and displayed on the

PC monitor or NBM-550 .

Marker function is available to provide accurate field strength and

frequency measurement.

EHP-50F is managed internally with a microprocessor that controls all the

main functions, from the battery charging to the serial communication with

the DSP unit.

Electric or Magnetic field is picked up by three sensors on the X, Y and Z

orthogonal axes. A Digital/Analog conversion follows which transforms the

signal into numeric information processed by a Digital Signal Processing

unit.



1-2 General Information

EHP-50F is housed in a small cubic housing. The bottom side panel

includes an optical fibre connector, extension rod screw, battery charger

connector, ON/OFF button and Status LED.

Fig. 1-1 Block diagram of the EHP-50F Analyzer

The magnetic sensor system is composed by three magnetic loops

positioned orthogonal each other. The electric sensor system is composed

by three orthogonal parallel capacitors installed on opposite side of the

magnetic loops.
