Model 9064
Programmable Filter/Amplifier
August 1998





Frequency Devices' Model 9064 programmable filter/amplifier system consists of a mainframe that houses the power supply, digital controller, interface electronics, sockets and mounting space for up to 16 plug-in quad or dual channel cards. It also provides a common input/output bus for monitoring, under control of a remote computer,via an IEEE-488 or RS-232 interface.

Each channel card contains configuration bits that can be identified by the controller and can be electrically connected to the l/O Bus in order to facilitate system check-out. Channel card options available are pre and post gain, single ended or differential input/output and operation in the bypass or active mode.


  • Wide selection of standard signal conditioning modules in a system configuration that provides versatility of use in many applications.
  • Simultaneous access over 64 channels offers a convenient way to provide filtering and gain.
  • Menu driven operation results in rapid set-up and configuration.
  • Universal card slots allow for replacement or swapping of channel cards without hardware or firmware changes.



  • Sonar, navigation and aerospace channel cards
  • Engine test and simulation
  • Acoustic, vibration analysis & control
  • Satellite and telecommunications
  • Automatic test equipment (ATE)
