BFI-V01

Product catalog summary

Overview
The BFI-V01 is a low-frequency signal generator (20 Hz to 80 KHz) known for its precision and stability, enhanced by an integrated GPS receiver. This feature allows for high stability frequency reference with minimal deviation. It can generate synchronous bursts with the PPS signal from the GPS system, useful for evaluating audio signal transit times with high accuracy.

Specifications
The BFI-V01 features a high stability OCXO with an aging rate of ± 1*10^-10/day, a 12-channel GPS receiver, and a high-definition bargraph display. It supports a dynamic range of 96 dB and a bandwidth from 20 Hz to 100 kHz, with frequency linearity of ± 0.1 dB. The device is fully digital, ensuring precision and repeatability.

Technical Specifications

GPS Section: 12 Channels L1 1575.42 MHz, < 50 ns PPS precision.
BF Inputs: Bandwidth 20 Hz to 100 KHz, Max Input Level 12 dBu, Max Output Level 20 dBu, THD + N: -75 dB at 400 Hz.
Signaling: RS-232 and optional RS-485 connections.
Supply: Dual power supply (95 Vac – 240 Vac) and battery pack.
Size: 1U/19'' rack, 300 mm depth, 1.5 Kg weight.

Features
The BFI-V01 includes a display and keyboard for easy configuration, a headphone jack, and is certified CE. It is designed for high-performance audio applications with stereo XLR connectors and AES-EBU digital interfacing.

Applications
The BFI-V01 is ideal for environments requiring synchronization signals, particularly in audio distribution chains, allowing for precise transit time measurements.

Digital Instruments 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...

Digital Instruments The scale used has a dual representation very practical in the broadcasting industry, in addition to the traditional representation of logarithmic type, ranging from - 40 dB to + 5 dB, a second staircase allows you to view the signal as a function of the percentage of modulation with the Convention that corresponds to 100% + 6 dBu. On the front panel of the display and the presence of the joystick allows easy navigation of the menus graph acting on the configuration parameters without necessarily the help of the PC. The dynamic range of the BFI-V01 is 96 dB with a bandwidth...
