The Stanford Research Systems FS710 is a 10 MHz AGC distribution amplifier that delivers seven stable outputs from a single input source. Built-in Automatic Gain Control compensates for up to 30 dB of cable loss, enabling 10 MHz reference distribution over distances approaching one mile. The transformer-coupled input accepts signals from 50 mVpp to 5 Vpp across the 10 MHz ± 100 kHz band, while all seven outputs deliver 1 Vpp into 50 Ω with ±10% stability. Output level is adjustable from 0.75 to 1.25 Vpp via front-panel potentiometer. Input and output impedance are jumper-selectable between 50 Ω and 75 Ω, with VSWR below 1.2 at 10 MHz on both ports. Harmonic distortion remains below -25 dBc across the output spectrum.
