Provides general information, test procedures and a number of test methods for both solid state and gas discharge microwave noise generators.
Lists the ratings, characteristics, inspection requirements, additional information and supplementary tests for a range of microwave noise generators produced to BS 9045:1981.
This European Standard specifies test methods for airborne noise emissions from heat generators in a test laboratory or at the place of installation. The test methods described in this European Standard, however, may be used for measuring the airborne noise emissions of the...
This Recommendation provides a set of recommendations for a specific evaluation of entropy sources to distinguish non-quantum physical entropy sources from quantum physical entropy sources. It also provides the following specification regarding quantum physical entropy sources: - a description of...
This European Standard applies to heat generators according to EN 15036-1, which are connected to chimneys/ducts which discharge combustion products via a duct into open air. The data measured according to this European Standard will probably be different from the noise radiated from...
This part of IEC 61400 presents measurement procedures that enable noise emissions of a wind turbine to be characterised. This involves using measurement methods appropriate to noise emission assessment at locations close to the machine, in order to avoid errors due to sound...
This signal generator generates a highly stable, continuous wave (CW), and modulated signal. The unit generates amplitude modulation (AM), frequency modulation (FM), phase modulation (ØM), and pulse modulation (PM) signals with internal or external signals for modulation on demand as...
INTRODUCTION The following noise measurement method applies to transistors whose noise has a Gaussian power distribution, to transistors whose noise has a flat (white) power distribution, and to transistors whose noise has a l/f (power inversely proportional to...
NOTE: This guide specification covers the requirements for 1800 rpm diesel engine-generator sets with ratings up to 2000 kW at 0.8 power factor intended for use in low voltage, non paralleling, emergency electrical power systems meeting requirements of NFPA 70, NFPA 99, and MIL-HDBK-1191.
This specification covers one type of mechanical smoke generator for use in the production of smoke screens.
This specification covers the general requirements for the Generator, Visual Image of the Target Selector Group, Fire Control XM-10 (Vulcan), hereafter referred to as the VIG.
The intent of the specification is to present a functional set of requirements which define the user and hardware interfaces while providing sufficient capability to meet the misfire patterns for compliance demonstration and engineering development. Throughout this requirement, any reference to...
This recommended practice establishes objectives for high performance control motor tachometer generators to be used with aeronautical and associated equipment in protective enclosures or completely within the shell of the aircraft so that they are subjected only to the internal climatic...
Products and Applications Included This standard describes installation procedures for generators and related accessories and systems that are permanently installed for on-site standby or emergency power generation that are typically fueled by natural gas or diesel. Such generators...
