Precision PF-1UA-FA
High Performance 8 or 16-Channel
Filter/Amplifier Systems

 

The PF-1UA-FA High Performance Multi-Channel Programmable Filter/Amplifier System is ideal for conditioning low-level voltage in front of high-resolution digital data acquisition systems.

Fully programmable compact 8-channel and 16-channel configuration are available; offering a choice of either 4 or 8-pole flat or pulse low-pass filters. The low-pass filters may operate in either a “flat” mode for maximally flat pass-band amplitude response with sharp roll-off or in a “pulse” mode for low phase distortion and optimized transient response.

Programmable pre- and post-filter amplifiers provide an overall gain of 8,192. Gain is distributed both before and after the filter to provide protection from large out-of-band energy or transients that could cause clipping before the filter, distorting the data.

The PF-1UA-FA also features a test input for injection of calibration signals into the channel input and a monitor output that allows for convenient monitoring of any channel output via a single BNC.

The system includes an Ethernet remote interface and is supplied with a Graphical User Interface (GUI) for local control.

Filter Characteristics

The PF-1UA-FA System has a variety of high-performance filter characteristics available for Low-Pass, High-Pass and Band-Pass Precision filtering. A choice of 4-pole and 8-pole low-pass filters provide versatility to address application in either the time or frequency domain.

Operating the PF-1UA-FA

For local control the PF-1UA-FA system is controlled via an Ethernet interface using the supplied spreadsheet-style GUI application running on a Windows PC. The GUI supports control of all channel and system features and allows for group control of channels. Up to eight PF-1UA-FA systems can be controlled by one GUI. System settings are restored on power-up or after a power fault. The settings are retained when the computer is disconnected even after a power-down and up. This allows the unit to be pre-configured for an application in which a computer may not be available for control.

The PF-1UA-FA system may be controlled remotely via an interactive command line interpreter that allows the PF-1UA-FA to function as a server on the network.
