NG-G1S-B3-03 Modular RF Noise Generator
The ETL Systems NG-G1S-B3-03 is a single-slot noise generator module covering 50–2500 MHz in a compatible GENUS 1U chassis. It provides broadband noise for RF testing, with maximum integrated output power of +10 ±5 dBm and noise power spectral density of −84 ±5 dBm/Hz.
Attenuation is adjustable over a specified 60 dB range, with up to 85 dB available control. The attenuator provides glitch-free and dropout-free adjustment in 0.25 ±0.25 dB steps. An optional signal injection input supports combining an external signal with the noise output.
Local touchscreen operation and remote Ethernet monitoring and control are provided through the compatible GENUS chassis. Connector configuration and the complete ordering suffix must be specified when requesting a quotation.

Configuration and Ordering Notes
This listing covers one NG-G1S-B3-03 noise generator module. The GENUS chassis, optional signal injection configuration, cables and other accessories are supplied only when included in the quotation.
At attenuation settings above 60 dB, noise output approaches the thermal noise floor of −174 dBm/Hz, and the specified noise output performance may not be maintained. The available 85 dB control range should not be interpreted as an 85 dB range of guaranteed output performance.
The module and chassis have different temperature and altitude ratings. The complete installation must remain within the limits of every installed component. Although the datasheet overview mentions outdoor chassis options, the tabulated module and chassis specifications state indoor use only; confirm any outdoor installation with ETL Systems.
Specify the connector type, optional signal injection input, chassis requirements and complete model suffix when requesting a quotation.
