Full textA calibração de padrões atômicos de tempo e freqüência, na forma atualmente realizada, apresenta o inconveniente de ter que se fazer o transporte do Padrão de Transferência até os laboratórios onde se encontram os padrões a serem calibrados. Isto se dá pelo fato destes laboratórios não possuírem uma maneira adequada para enviarem seus padrões ao Departamento do Serviço da Hora do Observatório Nacional (DSH/ON), órgão responsável perante o INMETRO na calibração em tempo e freqüência e detentor do Padrão Nacional. Propõe- se aqui a substituição do procedimento atual por um sistema de calibração automática via Internet, o que elimina a necessidade do deslocamento do Padrão de Transferência. Neste novo sistema de calibração, a referência passa a ser um receptor de GPS (Global Position Sistem), que assume o papel de Padrão de Transferência, ao qual o padrão a ser calibrado é ininterruptamente comparado. O acesso e armazenamento dos dados pelo DSH/ON é feito por meio de um programa que controla remotamente a calibração no laboratório via conexão pela Internet. O presente trabalho envolve uma comparação entre o sistema atual e o proposto aqui, todo o desenvolvimento e apresentação do programa computacional, a montagem de um sistema completo de simulação prática, inclusive com acesso remoto via Internet, a coleta e tratamento dos dados e a apresentação do procedimento utilizado para se chegar à incerteza de medição do sistema. Procura-se ressaltar a vantagem de um sistema de calibração automático, quanto à coleta dos dados, assim como a não dependência do transporte do Padrão de Transferência para a realização da calibração, evitando- se com isto a sua deterioração . Na conclusão deste trabalho a incerteza obtida é comparada com a do procedimento atualmente em prática e a partir desta comparação são feitas considerações quanto à implementação do novo sistema e ao uso do r eceptor de GPS como Padrão de Transferência.
The time and frequency calibration of atomic standards presents the inconvenience of the need of transportation of the Transfer Standard to the laboratories in which stay the standards to be calibrate. This happens because the laboratories do not possess a way to send its standards to the Departamento do Serviço da Hora do Observatório Nacional (DSH/ON), organ representative of INMETRO in Time and Frequency calibrations and detainer of the National Standard. This work intends the substitution of the procedure adopted today by a system of automatic calibration using Internet, eliminating the need of the displacement of the Transfer Standard. In this new procedure, the reference is t he Global Position Sistem (GPS) receiver, assuming the role of the Transfer Standard, to which the standard to be calibrate is compared continuosly. The access and storage of the data for the DSH/ON are made by means of a computer code that remotely controls the calibration through an Internet connection. The present work involves a comparison among both systems, the whole development and presentation of the computer code, the assembling of a complete system of practical simulation, the acquisition and data treatment and the presentation of the procedure used to obtain the measurement of the uncertainty. The advantage of an automatic calibration system, as well as of the collection of the data, is the fact that it not depending of the transportation of the Reference Standard for the accomplishment of the calibratio. As a conclusion of this work the obtained uncertainty is compared with the one in use today and based in this comparison we made considerations about the implementation of the new system and the use of the GPS receiver as Transfer Standard.

Se resalta la ventaja de un sistema de calibración automático, así como la no dependencia del transporte del Padrón de Transferencia para la realización de la calibración, evitando con esto su deterioración. En la conclusión de este trabajo se compara el error obtenido con el del procedimiento actualmente en práctica y a partir de esta comparación se realizan consideraciones respecto a la implementación del nuevo sistema y al uso del receptor de GPS como Padrón de Transferencia.

Full textThis paper will present and compare several definitions of telemetry radio frequency (RF) signal bandwidth. Measured spectra for different signals will be presented. The bandwidths of these signals will then be determined and measurement methods will be discussed. This discussion will include the effects of spectrum analyzer resolution bandwidth, video bandwidth and detector type. Finally, a proposed spectral mask will be discussed. This spectral mask can be used to calculate the required attenuation for a given frequency offset from the center frequency. The required attenuation is a function of the the bit rate or maximum frequency of interest and the transmitter power. This spectral mask is proposed to be part of the next edition of the Telemetry Standards, Inter-Range Instrumentation Group (IRIG) Standard 106.
