概要 The 5087A design allows a great deal of flexibility in configuring the product for your specific needs. The 10812A options provide an easy way to add other amplifier modules or to completely change the frequencies as your demands grow. These plug-in modules are ready to install into your existing 5087A motherboard after making a simple change to the jumpers per the installation instructions. They cover the input amplifiers, divider/multipliers, and output amplifiers that make up the family of 5087A options. Use the same option numbers when ordering the 10812A as you do for the 5087A.
