Microrad's mission is to design isotropic measuring systems
for electromagnetic safety. Our know-how is aimed at the sensors
of electric, magnetic, and electromagnetic fields and ranges
from static fields to millimeter waves. We have vanguard
solutions in each and every sector both for broadband and
selective measures. Our products have been developed in order to
operate in agreement with all principal international
series is available in three models. NHT 310 broadband meter from 0
Hz to 40 GHz. Integrated GPS NHT 3D complex signal analyzer with
selectivity from 1 Hz to 400 kHz and broadband operation mode from 100 kHz
to 40 GHz, remote analysis of the time/frequency domain via optical fiber.
Integrated GPS. NHT 3DL complex signal analyzer with selectivity from
1 Hz to 1 MHz and broadband mode from 100 kHz to 40 GHz. Time/frequency
domain instrument analysis, WI-FI migration of the user interface on
Android and OS smart phones. External GPS.
All meters work with interchangeable probes. They are made of aluminum/magnesium alloy and have an operating
autonomy of more than 24 hours.
NHT 3DL THE NEW
REFERENCE METER FOR EU DIRECTIVE 2013/35/EU
NHT 3DL has been designed to measure electromagnetic fields in compliance
with all the main international standards and regulations. This device is
able to adapt to future regulatory requirements using its completely
re-programmable system and structure.
3DL is ready for the 5G challenge, for the automotive/railway electric
traction industry, the medical diagnostics field and wherever regulated
industrial activities exist. The NHT 3DL has been specifically
designed to provide on board measurements of electromagnetic field
characteristics in both time and frequency domains.
bandwidth in both modes is 1 MHz.
to this solution it is possible to analyze and store complex waveforms
with transitory/pulse features.
the FFT Analysis mode, the device covers the 1 MHz band in four decades,
1/10/100/1,000 kHz with 1,000 points resolution per decade and automatic
peak search markers.
the Oscilloscope mode, it displays high-definition time frames with manual
trigger function and Amplitude/Time marker.
the broadband operating mode with RF probes from 100 kHz to 40 GHz, it
demodulates the pulse signal base band up to 500 ns, with automatic
measurement of Tau, PRF and Duty Cycle values.
mode has been specifically designed for the Radar sources recognition and
3DL can be completely remotely controlled via fiber optic or wireless
Microrad Waves is a software
application which allows the user to interact with the NHT 3D meter.
The Waves application allows the operator to perform domain analysis
and frequency measurements in both real time and in post processing
mode using data recorded during monitoring. Waves is easy to use,
modern (state of the art) and intuitive. It interfaces with the NHT
3D meter to provide an optimal measuring device. This software
application provides the operator with an integrated system capable
of performing fully automated analysis in the time and frequency
domain of ELF complex signals. The application is suitable for
analyzing complex and pulse signals in conjunction with a PC /
Tablet connected via fiber optic (through a converter Optical /
Marker and simultaneous reading
Zoom and Pan
Masks selectable according to the
Manual or Automatic trigger
Simultaneous calculation of the
indexes: WP10, II98, IB50, IRSS
Suppression of spectral
contributions according to the standard EN 50 500
All the displayed information can be
exported as image or data. Waves can be installed on systems running
Microsoft Windows XP, Vista, Windows 7, and 8 (32 or 64 bit).
MICROLINK SOFTWARE FOR THE NHT 310
The software used in conjunction with
the NHT 310 meter, provides the remote
management of the meter via optical fiber on PC through Optical/USB
converter. The software is direct and intuitive. It graphically
displays the amplitude/time output and reproduces the user interface
in real time. Complete with keyboard and graphic display, and
provides the table with all the data related to monitoring.
The data measured via single or
multiple monitoring are listed in a table providing the following
Axis X, Y, Z
Type of Probe (clicking on the
specific field opens a window with data from the corresponding
In the amplitude/time mode pan, zoom,
min and max functions are available, and the operator can select
linear or logarithmic scale. The graph allows the display of each
single axis, the resulting, of the mean and temperature value.
Additional software functions: Data export Alarm threshold setting
(buzzer) Moving average sample rate Sample rate and programmed start
of the monitoring Date and time setting
EMC VIEWER SOFTWARE DISPLAYS DATA FROM 8
The EMC Viewer allows the user to
connect to a virtually unlimited number of sensors (currently
configured for up to 8 sensors simultaneously). The software is
simple and intuitive, it displays the current values and trends
time/frequency allowing to export data and images.
Unit of Measure of the Field
