85572A-006
• Enables portable EMF measurements from 30 MHz to 6 GHz with all Keysight FieldFox analyzers
• Supports spectrum analyzer EMF channel power measurements
• EMF measurements on 5G NR control channels show the impact of the 5G signal over total RF exposure, requires over-the-air (OTA) 5G NR (for FieldFox B-Series only)
Introduction
Radio frequency electromagnetic fields (EMF) testing is key to evaluate total RF exposure in any given area due to deployment of various RF/MW networks, such as mobile phones, base stations, Wi-Fi, smart meters, IoT devices, and satellite and radar systems. Exposure levels set by government and regulatory agencies need to be verified in the field for compliance.
FieldFox with EMF measurements (Option 358), connected to the 85562A-006 EMF Triaxial Isotropic Antenna, enables EMF measurements in spectrum analyzer and over-the-air (OTA) 5G NR modes. The total field strength can be measured across the frequency band of interest.

Key Specifications for 85572A-006 Antenna
Keysight 85572A-006 EMF Triaxial Isotropic Antenna, originally designed and built in the AGOS NIRLab laboratory, contains three passive, independent, orthogonal antennas. If used with the supplied ferrite bead coaxial cable, it allows reliable measurement of radiofrequency electric fields that have an environmental impact in the vast majority of practical cases. The three orthogonal antennas are framed in the spherical radome.
