Rohde and Schwarz EMFT

The Rohde & Schwarz TS-EMF is a portable electromagnetic field measurement system for precise EMF spectrum analysis across diverse environments. It integrates with R&S spectrum analyzers—including FSH and FPH series—to deliver comprehensive RF measurements and ensure transmitter compliance with national and international exposure limits. The system employs isotropic antenna technology to detect fields independent of direction and polarization, supporting frequency-selective measurements from 9 kHz to 8 GHz. It provides detailed emission overviews by radio service, identifies individual emitters within subranges, and applies automatic linear field-strength summation below 10 MHz per ICNIRP standards. The TS-EMF handles analog modulated, digital, pulsed wideband, and radar signals using a true RMS detector and selectable measurement bandwidths. Its R&FEX software controls measurement sequences and allocates emissions across standard bands or as intermediate results. The system supports decoding of 3G and 4G signals with appropriate options and meets EN 50400, EN 50499, and ICNIRP regulatory requirements.
