I am on the east coast of the US this week visiting engineers who are designing some pretty cool stuff so this is just going to be a quick post. Back on Oct 17th I posted about Agilent's new 53200A series of universal counter / timers. Here I am going to talk about their graphing capabilities. In the past all a universal counter display gave you was a constantly changing long string of digits. Looking at this constantly changing long string of digits you could do a quick calculation in your head to figure out how far off you were from some reference value. Things that you probably could not calculate from the long string of constantly changing digits was how much random error is on my signal, is there multiple sources of random error, and is my systematic error changing with time. The histogram and trend chart capabilities found on the 53200 series of universal counters can give you information like that and more with a quick glance Below are two links to Youtube videos that provide an overview of the 53200 series histogram and trend chart capabilities. The actor that provides the overview in the video is also the designer of the features, enjoy.
