Press Release
Fully programmable signal conditioning system offer a number of advantages
over manually controlled units. Stored setups may be quickly downloaded to the
signal conditioner, the signal conditioner may be interrogated for programmed
settings and the signal conditioner can be amplified immediately. Precision
Filters’ Graphical User Interface (GUI) for the 28000
Signal Conditioning sets new standards for ease and flexibility of
signal conditioner control. The GUI operates on a computer running a standard Windows operating system, communicating with the 28000 frames via an
RS-232C connection.
The 28000 provides fully programmable transducer conditioning for charge,
IEPE,
strain, thermocouple or voltage inputs fully integrated in one system. The 28000
GUI furnishes control panels for configuration, setup, operation and test. On
power-up, the GUI automatically builds a display to control the exact set of
signal conditioners found in the 28000 mainframe. GUI displays and control
panels can be customized to users preference. Security features allow the user
to control access to critical programmed system parameters. GUI setup can be
stored for later retrieval and can be up-loaded to an Excel™ spreadsheet. A
Dynamic Link Library (DLL) is available to uses that desire the function of the
28000 GUI to be embedded in the measurement system GUI.
The GUI contains a collection of algorithms to automate tedious setup task
and databases that allow the user to import transducer information including
type, sensitivity, last calibration date and serial number. Based on user input,
the GUI apportions the gain in each channel to provide best signal to noise
ratio while minimizing the chance of an overload occurring on out of band
signals. Anti-aliasing filters can be programmed from user input on required
attenuation of aliases and channel sampling rate.
The performance verification of test instruments is a critical part of
insuring data integrity of any measurement system. The 28000 GUI features a
complete suite of tests that may be run on the instrument "in-place"
without disconnecting any cables or removing the system from the equipment rack.
The tests check out critical system specifications, are NIST traceable and are
the same manufacturing tests that are run at the factory. For facilities
compliant to ISO9001, these built-in tests will become a pat of your test
equipment verification procedures.
Precision Filters, Inc. utilizes its expertise in signal conditioning, filters, switch
matrices and data acquisition to provide measurement systems to research, industrial and
military markets worldwide.
