Aldena’s new compact Selective Electric Isotropic Triaxial Antenna Probe (SEP) is specifically designed to measure elements of the electromagnetic field in the 100 kHz to 3.6 GHz frequency range.
The spectrum analyzer and three-axis antenna (with an integrated RF switch) are fitted inside one unit. This facilitates the operator’s work in the field, who then only has to calibrate just one instrument instead of three (analyzer, cable and antenna).
Aldena explains that SEP’s three-dipole antennas are directly connected to the receiver, which minimizes isotropy error. In addition, users can connect SEP to a PC via a fiber-optic cable to control several functions via dedicated software including channel power, multichannel power, settable markers, maximum hold, RMS and average in a selectable time.
SEP weights 370 grams/13 ounces and can be mounted on drones.
