Narda SRM-3000 Selective Radiation Meter with 3501/03 3-Axis (27MHz - 3 GHz) Antenna and Accessories!
You are bidding on an Narda SRM-3000 Selective Radiation Meter with 3501/03 3-Axis (27MHz - 3 GHz) Antenna and accessories included. Calibrated by Keysight in Nov 2020. It is in perfect working condition and will arrive in a custom Pelican transit case.
The Selective Radiation Meter (SRM) is a hand-held selective measuring device
for safety analysis of RF and microwave electromagnetic fields. The SRM can be used
by broadcasters, radio network operators, measurement service providers and public
authorities to selectively measure the field exposure produced by individual telecom
services and assess the results in accordance with the applicable standards. Most measurements required in the mobile radio sector can be performed directly using the
hand-held device. The SRM immediately evaluates the results on site.
The SRM consists of a basic unit and a measurement antenna.
The basic unit contains a spectrum analyzer for the 100 kHz
to 3 GHz frequency range. It can be operated using anten nas from Narda or in combination with measurement antennas
from other manufacturers. The triaxial antenna allows isotropic
(non-directional) measurements from 50 MHz to 3 GHz, cover ing FM radio up to the W-CDMA and UMTS services.
