Newport 4832C Multi-Channel

 Optical Power Meter

This unit is in excellent condition and was pulled from working service.  It does not include the PCI interface card.   This is a current product.  Parts and service are available through Newport.

The 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 on-board 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. The system throughput is further optimized by using computers equipped with 486 or Pentium CPUs.

System flexibility allows the meter to be configured with one to a maximum of four channels, specified at the time of purchase. Future channel expansions can be performed by Newport. The 4832-C is compatible with all of Newports Low-Power, 818 Series detectors. Each channel is optimized to a specific detector, in order to maximize bandwidth and minimize noise.
