The Newport 4832-C is a PC-based multi-channel optical power meter designed for precise, high-speed measurements across up to four independent channels. Its distributed architecture separates the breakout box from the PC plug-in board, allowing remote placement up to 30 feet away to isolate sensitive analog circuitry from computer noise. The dual ADC architecture—combining a 12-bit high-speed converter and a 15-bit integrating converter—delivers measurement speeds to 3500 Hz on a single channel while maintaining NIST-traceable calibration capability.
