Narda EB 5091 NBM Shaped Probe, 2402/08B | 3 MHz - 50 GHz

The Narda EB 5091 NBM Shaped Probe, 2402/08B, measures electric fields with shaped frequency response according to IEEE standards for occupational/controlled environment. Electric fields from 3 MHz to 50 GHz can be detected. The Narda EB 5091 NBM Shaped Probe, manufactured by Narda Safety Test Solutions, is particularly suitable for measuring human safety limit values in mobile phone, telecom transmitter and broadcasting environment. The Narda EB 5091 contains 6 dipoles, three diode based and three thermocouple based dipoles. The correctly tuned overlap of two dipoles, one acting as a high pass filter the other as a low pass filter, provides a frequency sensitivity that mirrors a particular standard. Testing for compliance to that standard is very easy to perform, since you no longer have the need to know the emitted frequency.

The Narda EB 5091 is compatible with the Narda NBM-550 Broadband Field Meter.

ANSI/IEEE C95.1: Standard for Safety Levels with Respect to Human Exposure to Radio Frequency...
ANSI/IEEE C95.1:2019 offers safety limits for the protection of persons against the established adverse health effects of exposures to electric, magnetic, and electromagnetic fields in the frequency range 0 Hz to 300 GHz are presented in this standard. ANSI/IEEE C95.1:2019 sets these exposure limits as intended to apply generally to persons permitted in restricted environments and to the general public in unrestricted environments. These exposure limits are not intended to apply to the exposure of patients by or under the direction of physicians and medical professionals, as well as to the exposure of informed volunteers in medical or scientific research studies, and might not be protective with respect to the use of medical devices or implants. Compliance with IEEE C95.1:2019 In 2019 the IEEE updated the exposure reference levels (ERL), previously called maximum permissible expose (MPE). The ERL for unrestricted tier (lower tier) remain the same as in IEEE Std C95.1:2005. But the upper tier whole-body exposure ERLs above 300 MHz are different from those in IEEE Std C95.1:2005 to maintain a consistent 5× factor between tiers and to harmonize with ICNIRP guidelines. Per the chart below, the 2019 standard is significantly more stringent than the former 2005 standard, especially for frequencies above 2 GHz. As such, if you are using Narda Safety Test Solutions Shaped Response instruments that use the older IEEE C95.1:2005 “Shaping” for conducting RF Compliance measurements, you may exceed the ERL (MPE Limits) by a factor of two. Narda Safety Test Solutions has a full line of “Shaped Response” instruments which complies with the IEEE C95.1:2019 exposure reference levels (ERL).   Previous IEEE C95.1:2005 Standard The ANSI/IEEE C95.1:2019 test standard supersedes the previous C95.1:2005 standard. ANSI/IEEE C95.1:2005 offers recommendations to prevent harmful effects in human beings exposed to electromagnetic fields
