Frequency distribution amplifier is designed for ultra-low-noise distribution of sinusoidal signals 1–100 MHz with unity gain. It allows checking for signals availability via RS-232 interface. The basic model has 3 inputs / 12 outputs (3 modules 1 / 4). For the information about possible modifications, please contact us.

Key applications:
– time and frequency high precision measurement systems;
– time and frequency etalon systems.
