Minimizing cable-induced measurement errors in high current applications
Blog  
7/13/2011   Post a comment
In my job as an applications engineer, I’ve been fielding lots of calls about test and measurement problems that engineers encounter with high current applications like characterizing high power LED modules and high brightness light-emitting diodes (HBLEDs). At higher test currents, the appropriate cabling techniques are particularly important in obtaining repeatable and accurate measurements and maximizing performance.
Is your probing setup good enough to measure DDR3 signal integrity?
Design How-To  
7/13/2011   5 comments
DDD3 memory interface speeds have been going up steadily and are now approaching 2000 Mbps data rates. DDR4 is also nearly round the corner [6]. At these high data rates, it is becoming increasingly difficult to get good probing solutions which allow performing Signal Integrity characterization. High speed characterization is considered important for silicon based product development cycle. It is needed to understand the limitations of the current generation of DDR interface designs and to gear
