Precision PF-1U-FA
8 or 16-Channel Filter/Amplifier Systems with Programmable IEPE Current Source

 

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

Fully programmable 8-channel and 16-channel configurations are available in standard or high-performance models. A choice of 4 and 8-pole filter characteristics is available in low-pass and band-pass configurations. Fully programmable gain is distributed around the filter to reduce the possibility of clipping on out-of-band signals. A programmable current source is provided on each channel to interface the PF-1U to IEPE transducers, when required.

The standard PF-1U-FA configuration offers 4-pole low-pass filters with five programmable cutoffs and gain programmable to x1,024.

The high performance PF-1U-FA offers a choice of 4 or 8-pole low-pass and band-pass filters with cutoffs programmable from 1 Hz to 204.6 kHz. The high performance PF-1U-FA has an upgraded wideband (500 kHz) low-noise amplifier with transducer DC suppress capability. Gain is programmable to x8,192.

The PF-1U-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 aWindows based Graphical User Interface (GUI) for local control.

PF-1U-FA Benefits

  • Choice of 8-channel or 16-channel models
  • Compact and lightweight for portability
  • Rack mount or bench top
  • Low-pass filters operate in either 'flat' or 'pulse' mode
  • 'Flat' mode provides maximally flat passband amplitude response with sharp roll-off
  • 'Pulse' mode provides low phase distortion and optimized transient response
  • 4 or 8-pole low-pass and 8-pole band-pass filter options
  • Cutoff frequency settings to 204.6 kHz
  • Programmable gain up to 8,192
  • Test input and monitor output busses provide test support
  • Ethernet network interface
  • Stored up to four setups in non-volatile memory allowing pre-configured applications

Filter Characteristics

The PF-1U-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-1U-FA

For local control the PF-1U-FA system is controlled via an Ethernet interface using the supplied spreadsheet-style GUI application running on a Windows based PC. The GUI supports control of all channel and system features and allows for group control of channels. Up to eight PF-1U-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-1U-FA system may be controlled remotely via an interactive command line interpreter that allows the PF-1U-FA to function as a server on the network.
