Designed for amplification and distribution of frequency standard output signals while preserving their metrological characteristics.

The Instrument represents a set of buffer amplifiers. It comprises two amplification-distribution channels which comprise: an input amplifier (for 1, 5, 10 or 100 MHz depending on the amplifier type), an RF splitter and
5 output amplifiers.

The Instrument has a self-test system.
