Agilent/Keysight 5087-7001

The Agilent/Keysight 5087A is a modular distribution amplifier for frequency standard signal distribution in precision test and measurement systems. It accepts three input channels configured for 5 MHz or 10 MHz operation, with support for up to four different input frequencies, and delivers up to 12 individually adjustable output channels with voltage levels from 0 Vrms to 3 Vrms. Tuned output amplifiers ensure low distortion and excellent channel-to-channel isolation, while internal shielding minimizes noise and crosstalk across all signal paths.
