The function generator or power supply can be driven (slowly) with a triangular wave, so the I-vs-V curve can be collected in one pass using the two differential scope channels. I've used this technique for DC characterization of several parts, including LEDs.</p>

Sparkfun is a relatively small company and not a massive OEM like Phillips or Bose; minor mistakes either on the product pages themselves or in the IT infrastructure are bound to happen from time to time. Perhaps rephrasing to something like the following would be better:<p>"The LED ribbons are a really neat idea! Have you folks looked into an addressable version?</p><p>"Also, just a heads up, but it looks like some of the data sheets and electrical ratings are missing on the LED ribbons ;)"</p><p>I've met nearly everyone that works at Sparkfun at one time or another - while Sparkfun is certainly a business that makes money, the main goal of everyone on the team is to make and sell great things that allow folks to get the best out of their projects. This is a company and group of people that has sent out free revision boards at great cost of themselves when something as minor as a screen printing mistake or a wrong version of a bootloader is found (both things that are easily fixable by users). Please be nice to them :)</p></p>
