The Keysight 5087B wideband distribution amplifier is an economical solution for distributing signals from various frequency standards such as caesium, rubidium, quartz or GPS receivers.

Frequency standards typically have few outputs, each of which drives one load over short distances. When you have many devices requiring frequency reference inputs, or you need to deliver the frequency standard output from one building to another, the Keysight 5087B is the right choice. With our unique 3 Vrms output level capability, you can deliver further and with lower noise than with other distribution amplifiers.

The Keysight 5087B can be ordered now and replaces our time-proven 5087A. Please look at the Product Overview to learn about the new features and future options.

  • 1 MHz to 10 MHz wideband capability
  • Adjustable from 0.75 to 3 Vrms into a 50-ohm load
  • Two-input automatic switchover for input signal integrity (available later)
  • Internal backup Rb oscillator (available later)
