The Newport 4832-C Multi-Channel Optical Power Meter is a PC ISA bus plug-in card instrument for high-performance optical power measurements across ultraviolet to near-infrared wavelengths. It delivers NIST-traceable measurements with configurable single or multi-channel operation, high-speed data acquisition, and flexible detector compatibility. The modular architecture separates the plug-in board from a remote breakout box via shielded cabling, enabling placement up to 30 feet from the host PC while maintaining signal integrity in electrically noisy environments.
