General description of the
used NEWPORT 4832-C
for sale.
The Newport 4832-C Multi-Channel Optical Power Meter features multi-channel, high-speed and high-precision, NIST calibrated optical power measurements. The system consists of a breakoutbox connected to a PC plug-in board. The breakout box can be located up to 30 feet away from the PC, allowing its easy integration in manufacturing and assembly environments. 3500 Hz, single-channel data acquisition rates are achieved through a PCISA bus plug-in board. The onboard processor controls both the auto-ranging and data acquisition overhead. The exceptional combination of speed and accuracy is achieved by using a 12-bit, high-speed A/D for fast sampling and a 15-bit integrating A/D for the ultimate in precision DC measurements. The sensitive analog circuitry is kept in the breakout box, away from the noisy PC environment. All communications with the PC are performed via a high-speed serial bus. Measurement units of Watts, Amps or direct A/D data can be selected. In alignment or scanning applications requiring high-speed measurements, the A/D data and range information can be transferred directly to the PC, where further computations or conversion to dB or other units can be performed very quickly. Specifications. Wavelength: 190 to 1800 nm (sensor dependent). Power Range: -90 to +33 dBm (sensor dependent). Sampling Resolution/Rate: 15-bit at 15 Hz; 12-bit at 3500 Hz (single channel).
