- Oscilloscope history
This article discusses the history and gradual development of the Oscilloscope . Hand drawn oscillograms Image Oscillograph Joubert s Step by Step Method.png thumb 250px Illustration of Joubert s step by step method of hand plotting waveform measurements. ref Harvtxt Hawkins 1917 p 1844 Fig. 2589 ref The earliest method of creating an image of a waveform was through a laborious and painstaking process of measuring the voltage or current of a spinning rotor at specific points around the axis of the rotor, and noting the measurements taken with a galvanometer . By slowly advancing around the rotor, a general standing wave can be drawn on graphing paper by recording the degrees of rotation and the meter strength at each position. This process was first partially automated by Jules Fran ois Joubert with his step by step method of wave form measurement. This consisted of a special single contact ...

- Trigger holdoff
mergeto Oscilloscope date March 2011 Trigger holdoff is used in oscilloscope s to define a certain period following a trigger during which the scope will not trigger again. This makes it easier to establish a stable view of a waveform with multiple edges which would otherwise cause another trigger. Example Imagine the following repeating waveform br Image Scope Holdoff Waveform.gif 400px br The greenline is the waveform, the red vertical partial line represents the location of the trigger, and the yellow line represents the trigger level. If the scope was simply set to trigger on every rising edge, this waveform would cause three triggers for each cycle br Image Scope Holdoff Trigger1.gif 200px br Image Trigger2.gif 200px br Image Scope Holdoff Trigger3.gif 200px br Assuming the signal is fairly high frequency , your scope would probably look something like this br Image Scope Holdoff Alltriggers.gif 200px br Except that on the scope, each trigger would be the same channel, and so would be the same color. What we want to do is set the scope to only trigger on one edge per cycle, so we need to set the holdoff to be a little less than the period of the waveform. That will prevent if from triggering more than once per cycle, but still allow it to trigger on the first edge of the next cycle.

- Runt pulse
In digital circuit s, a runt pulse is a narrow Pulse signal processing pulse that, due to non zero rise time rise and fall time fall times of the signal, does not reach a valid high or low level. A runt pulse may occur when switching between asynchronous Clock signal clocks or as the result of a race condition in which a signal takes two separate paths through a circuit, which may have different delays, and is then recombined to form a glitch or when the output of a Flip flop electronics flip flop becomes Metastability in electronics metastable . Example Some oscilloscope s provide a method for triggering on runt pulses. The oscilloscope triggers when the signal crosses one of two voltage Threshold voltage thresholds , but not both. ref name Tektronix cite web publisher Tektronix title Oscilloscope triggering url http www.tek.com Measurement cgi bin framed.pl?Document Measurement scopes selection trigger.html&FrameSet oscilloscopes ref cite web publisher Tektronix title Diagram of a runt pulse url http www.tek.com Measurement scopes selection graphics t5.gif References reflist Category Digital electronics ... more details
