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.

Chromatic Dispersion
Chromatic Dispersion is a broadening of the input signal as it travels down the length of the fiber. Chromatic Dispersion results from a variation in propagation delay with wavelength, and is affected by fiber materials and dimensions.

Detector
A Detector is a signal conversion device that converts power from one form to another, such as from optical power to electrical power

Jitter
Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Polarization Mode Dispersion (PMD)
Polarization mode dispersion (PMD) is a form of modal dispersion where two different polarizations of light in a waveguide, which normally travel at the same speed, travel at different speeds due to random imperfections and asymmetries, causing random spreading of optical pulses. It is he difference between the maximum and minimum values of loss typically measured in ps/km^1/2.
