I own two Rigol oscilloscopes and have been using them since 2009. One of them is a 1052D, which has a 16 channel logic analyzer in addition to the standard oscilloscope functions. The other one is an 1102CA. They are very nice scopes and good value for the price. I especially like the displays, which have very wide viewing angle and can be seen from anywhere in the room. I use the math functions a lot, particularly the FFT and the differential. The logic analyzer work snicely, but I have only had to use it once, because we do most digital debugging with FPGA tools.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
