NEWPORT 4832-C Multi-Channel Optical Power Meter

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).

Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Bandwidth is the difference between the upper and lower frequencies in a contiguous set of frequencies within which a fiber optic component, link or network will operate.

Extinction Ratio (ER)
Extinction Ratio is the ratio of two optical power levels, of a digital signal generated by an optical source, (example a laser diode), where P1 is the optical power level generated when the light source is "on," and P0 is the power level generated when the light source is "off." The extinction ratio may be expressed as a fraction, in dB, or as a percentage.

Optical Signal-to-noise Ratio (OSNR)
Optical Signal-to-noise ratio is the ratio between the signal power and the noise power in a given bandwidth. Most commonly a reference bandwidth of 0.1 nm is used. This bandwidth is independent from the modulation format, the frequency and the receiver. For instance a OSNR of 20dB/0.1nm could be given, even the signal of 40 GBit DPSK would not fit in this bandwidth. OSNR is measured with a Optical Spectrum Analyzer. It is generally measured at the wavelength of interest.

Repeatability is the variation in a number of repeated measured quantities when measurement conditions are changed and restored. The value corresponds to half the spread between the minimum and maximum value measured.

Wavelength Repeatability
Wavelength Repeatability is the random uncertainty in reproducing a wavelength after detuning and re-setting the wavelength. The wavelength repeatability is ± half the span between the maximum and the minimum value of all actual values of these wavelengths. Example test condition: uninterrupted TLS output power, constant power level, temperature within operating temperature range, coherence control off, short time span. Note: NOTE The long-term wavelength repeatability can be obtained by taken the wavelength repeatability and wavelength stability into account.
