Broadband Calibrated Noise Sources
-
Fairview Microwave’s calibrated noise sources cover frequency bands from 10 KHz to 18 GHz. Their performance specifications include output ENR levels ranging from 15 dB to 30 dB and typical VSWR levels as low as 1.25:1. Depending on the model, calibrated frequency points are at 10 MHz, 100 MHz, 1000 MHz, 2000 MHz and 1 GHz steps. The temperature coefficient of these noise sources is < 0.01 dB/°C and noise output variation is < 0.1 dB/%V.

Turnkey Solution for Unattended Noise Monitoring
NoiseScout
-
NoiseScout provides a comprehensive but easy-to-use 24/7 noise monitoring solution. Noise levels are recorded on-site by the XL2 Sound Level Meter and are available online for monitoring and download. NoiseScout is aimed at both short term noise assessments and long term monitoring applications. During acquisition, automated email alerts allow noise issues to be addressed before a non-compliance condition arises. NoiseScout displays the noise levels measured by the XL2 Sound Level Meter live in your web browser. The measurement data recorded out in the field is presented online in charts and dashboards. Multiple noise level meters can be monitored simultaneously within the map view, thus providing localized geographic visualization for all noise levels at a glance. Identified users can access all their projects, control their monitors or create basic view modes, allowing stakeholders to oversee their noise level data.
