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.

Coherence Length
Average distance over which superimposed waves lose their phase relationships

Linewidth
Linewidth is the width of a spectral line in terms of wavelength, wave number and frequency.

Power Flatness Versus Wavelength
When changing the wavelength at constant power setting and recording the differences between actual and displayed power levels, the power flatness is ± half the span (in dB) between the maximum and the minimum of the measured power levels.

Spectral Width
Spectral Width is the wavelength interval over which the magnitude of all spectral components is equal to or greater than a specified fraction of the magnitude of the component having the maximum value. In optical communications applications, the usual method of specifying spectral width is the full width at half maximum. This is the same convention used in bandwidth, defined as the frequency range where power drops by less than half (at most -3 dB).

Telecom Bands
Optical fiber communications typically operate in a wavelength region corresponding to one of the following Bands. O Band (original): 1260–1360 nm. E Band (extended): 1360–1460 nm. S Band (short wavelengths): 1460–1530 nm. C Band (conventional): 1530–1565 nm. L Band (long wavelengths): 1565–1625 nm. U Band (ultralong wavelengths): 1625–1675 nm
