Although this maybe a bit out of the gpete realm I felt I had to mention that about a month ago Agilent released the Infiniium 90000 X-Series oscilloscope family, which is the fastest most accurate scope family ever. The X-series offers up to 32 GHz of true analog bandwidth in a scope!! This is truly a milestone in test and measurement engineering. I can remember back in '99 digital scopes were just starting to take over and 500 MHz of bandwidth was considered high! Technology is sure moving fast. I have not yet had a chance to play with one of these amazing instruments yet, but I did get a chance to speak to some of the people from the R&D team that worked on them. The engineering that went into the timing, digitizing, and signal conditioning is pretty amazing. Not only that the engineering that went into the probes (up to 30 GHz probing)is amazing. Seeing scopes with this much bandwidth and accuracy makes me think that eventually we may see the spectrum analyzer, signal analyzer, and scope merge into a single instrument (FFTs are a common feature on most scopes today). It is still years off but I can see it coming.
