Signal generator BFI-V01

BFI-V01 is a generator of low frequency signals (20 Hz to 80 KHz) extremely precise and stable over time. The integrated GPS receiver makes it possible to regulate the internal oscillator providing a high stability frequency reference with a maximum deviation of typical systems enslaved equal to 10-12 / day. BFI-V01 is also able to generate synchronous burst with the PPS signal provided by the system-GPS UTC adding them, if necessary, to the audio signal coming from the production studio, in a continuous or programmable by the operator without necessarily intervene on the wiring of the chain audio same. BFI-V01 is used everywhere it is required to insert a synchronization signal to every note. Its main application is identified where it is necessary to evaluate the transit time through a distribution chain of an audio signal. The ability to generate burst isochronous to the PPS signal from the UTC-GPS system ensures the user to be able to derive the transit time from the insertion point to the point of analysis with an accuracy of 10 ns. BFI-V01 was developed to finalize plants operating in isochronous and isomodulated mode, by inserting the burst signals in the main point of the audio distribution (for example, the production studio) is possible to derive the various sites transmitting the time that the audio signal same employs to reach the place of measurement. The method of measurement is based on the comparison between the instant of arrival of the burst signal and the PPS signal from the GPS receiver. The accuracy of the measurement depends on the instrument used for this assessment.
