Stanford Research FS710 10 MHz AGC Distribution Amplifier

The Stanford Research FS710 is a 10 MHz AGC distribution amplifier that accepts a single 10 MHz reference input and delivers seven independently buffered outputs, each capable of driving extended cable runs. Built-in automatic gain control compensates for signal loss and maintains output amplitude consistency across all channels, supporting cable lengths up to one mile. The unit accepts input signals from 35 mV to 5 VAC peak-to-peak and delivers stable 1 Vpp (into 50 Ω) or 2 Vpp (into 10 kΩ) outputs with up to 30 dB of AGC gain.
