Narda Nardalert XT A8861 Personal RF Monitor | 10 MHz - 100 GHz

Discontinued
The Narda Nardalert XT A886 has been discontinued.
The Narda Nardalert XT A8861 Personal RF Monitor is designed to satisfy the needs of all individuals who use a personal RF monitor. The patented sensor design of the Narda Nardalert XT A8861 detects the electric field over an extremely broad frequency band regardless of signal format or polarization. The Narda Nardalert XT A8861's ultra-broadband sensors cover almost the entire usable RF spectrum in a single monitor, and models are available that closely conform to all major worldwide standards. The adjustable alarm feature allows one alarm to be set at a level equal to the upper tier of two-tier standards, such as the “Occupational” or “Controlled” limits, while the second alarm can be set to the lower tier, such as the “Action” or “General Population” limits. The unique tri-sensor design handles every possible signal format, from complex multi-signal communication environments to military platforms with both communications and radar signals.

The 8861 Series is designed for applications where the user will be in close proximity to strong ELF fields, such as from 50/60 Hz power lines. These monitors are very similar to the standard, full-featured series except that the inside of the housing has a special conductive coating that blocks the ELF signals. The low frequency range of these monitors is reduced by the coating. The Narda Nardalert XT A8860 fulfills the following standards: FCC 1997 (Occupational / Controlled), Japan RCR-38 (Controlled), ONORM S 1120, 1992 (Occupational).

The Narda Nardalert XT A8861 is part of the Narda Nardalert XT Series.
