Device classes for the PFA-2 filter from Precision Filter Inc..

The PFA-2 filter is a high-precision, low-noise analog filter commonly used in laboratory instrumentation and signal conditioning setups. It is suitable for applications requiring clean signal output, such as spectroscopy, low-level voltage measurements, signal recovery and high-resolution data acquisition.

The class PFA2Filter has been tested with a PFA-2 (with option H) unit. Verify compatibility with your specific filter variant before use, especially for units with custom or user-modified settings.
