KEITHLEY 2520 Pulsed Laser Diode Test System

The Keithley 2520 Pulsed Laser Diode Test System is an integrated, synchronized system for testing laser diodes early in the manufacturing process, when proper temperature control cannot be easily achieved. The Model 2520 provides all sourcing and measurement capabilities needed for pulsed and continuous LIV (light-current-voltage) testing of laser diodes in one compact, half-rack instrument. The tight synchronization of source and measure capabilities ensures high measurement accuracy, even when testing with pulse widths as short as 500ns. Specifications: Pulse Laser Diode Test System w/ Remote Test Head: Integrated solution for in-process LIV production testing of laser diodes at the chip or bar level. Sweep can be programmed to stop on optical power limit. Programmable pulse on time from 500ns to 5ms up to 4% duty cycle. Pulse capability up to 5A, DC capability up to 1A. 14-bit measurement accuracy on three measurement channels (VF, front photodiode, back photodiode). Measurement algorithm increases the pulse measurement's signal-to-noise ratio. Up to 1000-point sweep stored in buffer memory eliminates GPIB traffic during test, increasing throughout. Digital I/O binning and handling operations IEEE-488 and RS-232 interfaces.

*This is a Web introductory price for one calibration of the KEITHLEY 2520. Price does not in most cases include measurement performance data. 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.

Absolute Wavelength Accuracy
Absolute Wavelength Accuracy is the maximum difference between the actual wavelength and the displayed wavelength of the Optical Source. Wavelength is defined as wavelength in vacuum.

Decibel (dB)
A unit of measurement of optical power which indicates relative power. A -10 dB means a reduction in power by 10 times, -20 dB means another 10 times or 100 times overall, -30 means another 10 times or 1000 times overall and so on.

Nanometer (nm)
A unit of measure used to measure wavelength of light, meaning one one-billionth of a meter

Relative Intensity Noise (RIN)
Relative intensity noise (RIN), describes the instability in the power level of a laser. The noise term is important to describe lasers used in fiber-optic communication and LIDAR remote sensing. It is the square of the (spectrally resolved) RMS optical power amplitude divided by the measurement bandwidth and the square of the average optical power, expressed in dB/Hz.

Total Return loss
In an optical fiber, the loss that takes place at any discontinuity of refractive index, especially at an air-glass interface such as a fiber endface, at which a fraction of the optical signal is reflected back toward the source. RL = - 10log10 (Preflected/Preference)
