Microrad’s NHT 3DL Electromagnetic Field Analyzer is designed to measure electromagnetic fields in both time and frequency domains and in compliance with all the main international standards and regulations
Saelig Company, Inc. has introduced the Microrad NHT 3DL Electromagnetic Field Analyzer, which is designed to measure electromagnetic fields in both time and frequency domains and in compliance with all the main international standards and regulations. A wide selection of interchangeable electromagnetic field probes allows this handheld analyzer to measure complex electric and magnetic fields from DC to 1MHz in Selective Mode, and 0 to 40GHz in Wideband Mode. The Monitoring Mode function allows for received signals from the attached probe to be recorded to the instrument’s non-volatile internal memory. The NHT 3DL can analyze and store complex waveforms with transitory and pulse characteristics. This saved data can then be downloaded to a PC in order to extract relevant information acquired during the monitoring. Battery power allows the user to perform monitoring tasks for at least 24 hours. NHT 3DL can be entirely controlled remotely via fiber optic or wireless (Wi-Fi) connections. Outdoor monitoring in all weather conditions can be carried out, due to the NHT 3DL’s IP67 enclosure.
The NHT 3DL when operating in broadband mode with E series probes covers frequencies from 100kHz to 40GHz. When utilized in conjunction with the ER series probes it can demodulate and rebuild radar signal pulses up to 500ns, providing automatic measurement of Tau, PRF and Duty Cycle values. This mode is particularly useful for radar source recognition and measurement. In the FFT Analysis Mode, the device covers the 1MHz band in four decades, 1/10/100/1,000kHz with 1,000 points resolution per decade and automatic peak search markers. In the Oscilloscope Mode, it displays high-definition time frames with manual trigger function and Amplitude/Time marker. The NHT 3DL, when combined with the new 33S Triple Probe, can measure static magnetic, magnetic, and electric fields from 1Hz to 1MHz in a disjoint/combined mode.
The operator interface is based on a high-resolution color touch screen display. It can be remotely controlled via Wi-Fi or fiber-optic connection, with the display shown on Windows and Android devices. The Microrad NHT 3DL analyzer is designed to operate also as an area monitor.
