Rental/Lease Information Request

The Agilent 5087A distribution amplifier provides the flexibility required for distributing signals from the output of high-quality frequency standards. Low distortion and excellent isolation make it ideal for providing multiple outputs from atomic or crystal frequency standards. The three input channels will accept 10 MHz or 5 MHz. The number of outputs for each channel is selectable up to a total of 12. Voltage levels are individually adjustable from 0 Vrms to 3 Vrms for each of the output channels.

Because the 5087A is modular, you can configure it for a variety of distribution needs using special combinations of input and output modules. Shielding around each input and output plug-in amplifier ensures minimum noise and crosstalk. The tuned output amplifiers provide clean signals and high channel-to channel isolation. A 115/230 VAC power supply provides well-regulated current for the amplifiers. Line voltage fluctuations have no measurable effect on the amplitude or phase of the outputs. Provision for external 22-30 Vdc connections ensures uninterrupted operation in the event of AC failure.

When you need to expand the capabilities of your distribution amplifier , you can order individual input and output modules using Agilent model number 10812A.
