The invention discloses a
signal conditioning board with an
electromagnetic shielding function, which comprises a circuit board which is designed by adopting the appearance of a PCI (
peripheral component interconnect) board and a shielded
enclosure, wherein the circuit board adopts an
electromagnetic compatibility processing mode of a conventional circuit, and the shielded
enclosure comprises a
front cover plate, a rear cover plate and a baffle plate. According to the
signal conditioning board, a
signal conditioning circuit in a target simulator is designed into a circuit board with the appearance of the standard PCI board, the shielded
enclosure is added on the whole circuit board, therefore, the
electromagnetic environment of the
signal conditioning board in an industrial
personal computer is effectively improved, and the equipment failure caused by a
weak signal interfered by other electrical signal in the industrial
personal computer is avoided. The
signal conditioning board is fixed in a PCI groove in the standard industrial
personal computer by using the fixed mode of the PCI board, the power supply of the industrial personal computer is directly used to supply power for the
signal conditioning board, the whole signal conditioning board meets the installation requirement of the standard industrial personal computer (40 cm * 30cm * 25cm), so that the portable and
integrated design of the equipment is realized, and the signal conditioning board is compact in structure, small and light and convenient to carry and used in different places.
