Product Brochure Electromagnetic Field Measurement System EMF Option 0444 700 MHz to 3000 MHz (for MS2711E) 700 MHz to 4000 MHz (for MS2712E, MT8212E) 700 MHz to 6000 MHz (for MS2713E, MT8213E) 9 GHz to 43 GHz (for MS2720T) Since 1895 Electromagnetic Field Measurement System Anritsu’s ElectroMagnetic Field (EMF) Measurement System is designed to measure radiation compliance with various national standards for personal safety set by governmental regulatory authorities. Many countries have mandated EMF safety testing in areas where cellular or other high power transmission antennas are located. The EMF option is primarily targeted to both cellular operators and government regulators. Additionally, contractors and small service companies perform building inspections and field surveys to monitor radiation exposure intensities in areas situated near transmission antennas. Anritsu’s EMF Measurement System is designed to be easy to use, while providing the user with numerous automated features which will enable them to do their job quickly and more efficiently. Electromagnetic field measurements (EMF, Option 0444) are available on the following Anritsu Spectrum Master™ and Cell Master™ products: MS2711E, MS2712E, MS2713E, MS2720T, MT8212E and MT8213E. Firmware version 1.56 or later is required for the MS2711E/12E/13E and MT8212E/13E. For the MS2720T, firmware version 1.12 or later is required. EMF Option (0444) provides the capability to measure electromagnetic field radiation when used in conjunction with an Anritsu isotropic antenna. Automated measurements can be taken using user-definable time intervals. EMF System Key Features and Benefits • Limit lines that are user-settable at various power levels across the spectrum • Limits can be saved for recall at a later time • Axis dwell time is user-settable (time that each axis [ X, Y, and Z ] measures radiation before switching to next axis) • Pass/Fail indicators on screen for immediate feedback on test results • Automatic save feature for easy storage of measurement results to internal memory (auto-logging) or USB stick • Results provided for maximum, minimum, average of all measurements conducted • Clear display of measurement status, measurement time, number of measurements taken, and most other user settings • Measurement time is user-configurable • Pre-amp standard for measurements of low-level signals (optional for MS2711E) Available field strength units include the following: Spectrum Analyzer Mode: dBm/m2, dBmV/m, dBuV/m, V/m, W/m2, dBW/m2, A/m, dBA/m, W/cm2 LTE and TD-LTE Mode: dBm/m2, V/m, W/m2 W-CDMA Mode: dBm/m2, V/m, W/m2, % of Limit (V/m), % of Limit (W/m2) For wideband radiation measurements, the EMF option operates in Spectrum Analyzer mode. Total radiation from all sources can be measured over the frequency band desired. The EMF option will also conduct radiation measurements of demodulated signals in specific frequency bands. In this way, measurements can be extrapolated assuming a fully-loaded traffic channel in order to present a worst-case analysis. Option 0444 will work with demodulated signals of the following types: • W-CDMA • LTE • TD-LTE If the user desires to measure EMF with a demodulated signal, the appropriate demodulation option also will need to be purchased. Additionally, Option 9 (demodulation) will need to be purchased if not offered as standard with the Spectrum Analyzer being used. Customers with Spectrum Analyzers purchased previously may upgrade their units with the EMF Option 0444. If EMF demodulation measurements are required, the appropriate demodulation option will also need to be purchased and installed. Page 2 of 8 Electromagnetic Field Measurement System Isotropic Antenna In order to conduct EMF measurements, an Anritsu isotropic antenna is required. Anritsu offers the 2000-1791-R isotropic antenna for use with this system. The 2000-1791-R operates over a frequency range of 0.7 GHz to 6 GHz. This antenna is a tri-axis E-Field sensor with an integrated RF switch device, microcontroller, and memory. Each of the three sensors is situated orthogonally inside the antenna housing to transmit and receive a spherical radiation pattern. In this way, all radiation at the antenna’s geographical position is measured, regardless of direction of arrival. Isotropic Antenna 0.7 GHz to 6 GHz 2000-1791-R The RF switch, microcontroller, and memory inside the antenna are controlled by firmware in the Spectrum Analyzer via a USB cable. The microcontroller operates the RF switch, controlling which probe is active. Once all three probes are switched, a composite RMS calculation is made. The memory inside the antenna is used to store parameters associated with that particular antenna. This includes serial number, date of calibration, antenna frequency range, and calibration factors. Each isotropic antenna is individually calibrated over its entire frequency range. The antenna factors are stored in the antenna’s memory and automatically downloaded into the Spectrum Analyzer once the antenna USB cable is inserted. Page 3 of 8 Electromagnetic Field Measurement System EMF Measurements on Demodulated Signals Users may purchase the EMF option in order to make radiation power measurements in Spectrum Analyzer mode. These are power measurements for either narrowband or wideband field strength measurements across the frequency range of the Spectrum Analyzer and isotropic antenna being used. Additionally, EMF testing can be conducted on demodulated signals in various cellular channels. This includes the LTE, TD-LTE, and W-CDMA standards. To measure demodulated W-CDMA signals, Option 0035 is required for the MS2712E/13E and MT8212E/13E platforms. For MS2720T, Option 0081 is required for W-CDMA. Option 0009 is also required for the MS2712E/13E and MS2720T platforms for W-CDMA demodulation capability. The field strength of the pilot channel (P-CPICH) is measured for all such signals present. Results are then displayed for each individual scrambling code as well as for total power levels for all measurements combined. Additionally, the analog signal strength across the channel is measured and displayed for comparison. In order to present a “worst case” result, extrapolation factors can be automatically calculated and displayed where a fully loaded traffic channel is assumed. Sample Display of W-CDMA EMF Measurement For LTE and TD-LTE, Options 0546 and 0556 respectively are required for the MS2712E/13E and MT8212E/13E platforms. Option 0083 is required for either LTE or TD-LTE on the MS2720T platform. Option 0009 is also required for the MS2712E/13E and MS2720T platforms for LTE or TD-LTE demodulation capability. Primary Synchronization Signals (P-SS), Secondary Synchronization Signals (S-SS), and Reference Signals (RS) are measured and displayed based on each Cell ID received. In addition, the total radiation field resulting from all cell site signals combined is calculated and displayed. The analog signal strength across the channel is also measured and displayed for comparison. In order to present a “worst case” result, extrapolation factors can be automatically calculated and displayed where a fully loaded traffic channel is assumed. See the picture below for a sample display of an LTE EMF measurement. The display for the TD-LTE EMF measurement is identical.
