PF-1U-FA Filter/Amplifier Systems
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.
Choice of 8-channel or
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

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.
