Low cost digital storage scopes are big on features
Product News  
4/25/2005   Post a comment
It doesn't make economic sense to equip a field technician or an engineering lab bench (or even a school lab) with a high-speed expensive instrument when a 60-MHz or 100-MHz scope will fill the bill. Agilent Technologies addresses that with four portable digital-storage oscilloscopes that sell for about 20 percent less than competing scopes. With bandwidths of 60-MHz, 100-MHz, 150-MHz, and 200-MHz, Agilent's new DSO3000 Series are dual-channel instruments with big color LCDs.
