  • Standardized tests versus creativity
  • Magflux, Have you ever talked to a teacher about this? I don't think this has anything to do with teacher unions. It could be school administrators and some school principals who tell teachers to "teach to the test." They do it to make themselves and their districts/schools look better. I believe that many teachers and school principals feel that the standardized tests get in the way of real teaching, as in teaching students to think.

  • 10 More tricks to extend oscilloscope usefulness
  • In my days as a print editor, publications had styles. EDN and Test & Measurement World had different styles, even though they were in the same company. For example, TMW always had a space between a number and its units, as in 10 V. EDN would sometime put a space between and sometimes not. I think it depended on the number of characters in the unit, something like 10 V but 10 mA. I could never keep it straight.

  • USB oscilloscope gets jump in update rate
  • bob, For many years, the trend was to offload as much as possible from the PC. Let the instrument do the signal processing and the PC was more of an executive. Now that's changing and the PCs are starting to take the load off the instruments. That lowers the cost of the instrument and the cost of the overall system given the low cost of PC computational power. Some years ago, many systems needed dedicated DSPs for signal processing, then that moved to FPGAs and now in some cases, to PCs. Expect more of that in the coming year.

  • Classic oscilloscope front panels show how it's done
  • As you old timers retire, the following generations will use touch screens or virtual front panels. Then, they'll use voice commands (already available) or Google Glass. Eventually, you'll be able to control your scope by just thinking.

  • "Engineers very quickly learn to hold a scope probe with their left hand and do all the knob turning with their right hand" Maybe the controls should be on the left so you can hold the probe with your right hand. It's kind of like how most kitchens have the sink prayer and the dishwasher on the right side. But really, the dishwasher should be on the left. That way, you rince the dish with the sprayer in your right hand and hold the disk with your left. If the dishwasher is to your left, you use the same left. hand to place the rinsed dish in the washer. With the dishwasher to your right, you have to put the sprayer down and switch the dish to your right hand to put it in the washer. Then you pick up the sprayer again with your right hand. That's lots of extra work. When we designed out kitchen, we put the dishwasher to the right of the sink for resale value. Go figure.
