1. Displaying the Trigger Source You do not have to display a channel to use it as Normal and Auto Mode Use Normal trigger mode when you want to trigger only on a valid event Use Auto trigger mode when you want the acquisition to occur even when there is not a valid trigger event Also choose Auto when you want a rolling waveform with no trigger at the slower time base settings See External Trigger The trigger level range for the EXT setting is 0 8 V to 0 8 V For best external trigger performance apply a square wave signal with amplitude greater than the specified minimum level range and with well defined transitions Alternating Trigger Alternating trigger sequentially uses each active channel as a trigger source from the lowest numbered active channel to the highest numbered active channel Alternating trigger is available in all trigger menus except for Alternating trigger uses the current trigger settings to trigger on all active channels there is not a separate trigger setup for each channel Therefore the trigger settings must be able to trigger on all active signals in order to produce a stable triggered display If one or more of the source signals do not meet the trigger settings the oscilloscope either waits for that source channel to trigger Due to image persistence all alternating trigger active channels may appear to be synchronized However this does not mean that the displayed signals are synchron

9. Taking Gray Scale Measurements Using cursors is often the best way to take simple measurements on waveforms that contain significant gray scale information The automatic measurements operate only on the latest acquisition not on the previous acquisitions that are displayed in gray scale However you can set the cursors to surround and measure the gray scale area of the waveform High Low Setup The oscilloscope determines the 10 50 or 90 levels of the waveform and then uses them to calculate the measurements There are two possible methods Histogram or Min max Auto Select allows the oscilloscope to determine the method used Histogram sets the values statistically it finds the most common value either above or below the midpoint depending on whether it is defining the high or low reference level Since this statistical approach ignores short term aberrations overshoot ringing noise histogram is the best method for measuring digital waveforms and pulses m Min max uses the highest and lowest values of the waveform record This method is best for measuring waveforms that have no large flat portions at a common value such as sine waves and triangle waves m Auto Select chooses one of the above methods automatically depending on the signal characteristics Auto Select chooses the histogram method if the histogram contains prominent peaks If not Auto Select chooses the min max method Measurement Gating You can use the g
