Agilent/Keysight 5087-7098

The Agilent/Keysight 5087-7098 (5087A) is a modular distribution amplifier that distributes signals from high-quality frequency standards with low distortion and high isolation. It accepts input frequencies of 5 MHz or 10 MHz (with some configurations supporting 1 MHz and 0.1 MHz), and provides up to 12 selectable output channels with individually adjustable voltage levels from 0 Vrms to 3 Vrms per channel.
