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.

Chirp
A change in the optical frequency caused by direct modulation of the laser. A chirp is a signal in which the frequency increases ('up-chirp') or decreases ('down-chirp') with time. In some sources, the term chirp is used interchangeably with sweep signal.

Isolation
The extent to which optical power from one signal path is prevented from reaching another signal path.

Polarization Extinction Ratio
Polarization Extinction Ratio is the ratio of optical power in the slow axis of the polarization maintaining fiber to optical power in the fast axis within a specified wavelength range.

Sidemode Suppression Ratio
Sidemode Suppression Ratio is the ratio of average signal power to the optical power of the highest sidemode within a distance from 0.1 to 6 GHz to the signal’s optical frequency, expressed in dB.

Wavelength Stability
Wavelength Stability is the change of wavelength during given time span, expressed as ± half the span between the maximum and the minimum of all actual wavelengths.
