Agilent/Keysight 5087-7054

The Agilent/Keysight 5087-7054 is a modular distribution amplifier that delivers multiple synchronized outputs from atomic or crystal frequency standards. It accepts 10 MHz or 5 MHz input signals across three input channels and distributes them to up to 12 selectable output channels with individually adjustable voltage levels from 0 Vrms to 3 Vrms per channel. The modular architecture accommodates custom input and output configurations, enabling flexible frequency routing - including simultaneous distribution at 5 MHz, 1 MHz, and 0.1 MHz from a single standard.

Technical Specifications

• Input Frequencies: 10 MHz, 5 MHz (configurable to 1 MHz and 0.1 MHz outputs)


• Input Channels: Three


• Output Channels: Up to 12 (selectable configuration)


• Output Voltage (per channel): 0 Vrms to 3 Vrms, individually adjustable


• Power Supply: 115/230 VAC, well-regulated; external 22–30 Vdc backup provision


• Line Voltage Stability: No measurable effect on output amplitude or phase from line fluctuations

Key Features

• Tuned output amplifiers deliver clean signals with minimal distortion


• High channel-to-channel isolation through shielded input and output amplifier modules


• Front-panel meter with 16-position switch for input, output, and voltage monitoring


• All connectors and fuses located on rear panel for streamlined integration


• Modular plug-in architecture supports diverse input/output configurations

Typical Applications

• Signal distribution from atomic and crystal frequency standards


• Multi-output frequency reference generation for test systems


• Data acquisition systems requiring synchronized, low-distortion reference signals


• Signal generation equipment with distributed frequency references

Compatibility & Integration The 5087-7054 integrates directly with high-quality frequency standards and functions as a distribution hub within larger test and measurement systems where multiple synchronized clock or reference signals are required.
