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 Newport’s Low-Power, 818 Series detectors.
Each channel is optimized to a specific detector, in order to maximize
bandwidth and minimize noise.
