content: Hi,On many of dave's videos he uses his agilent scope which can capture the entire waveform at once. The biggest and most expensive mistake I made was to buy this shit scope from farnell. It cost me 300 quid and I was told it doesn't trigger very well by my mentor. It does the job sort of.I was wondering is there a way I can get my shit scope to do a single shot mode or is it that prestigious feature that only expensive scope have. If so how expensive is expensive? Not that I'll be able to afford one soon. I'll need to save up and work hard. Is it more like in the region of 1000 pounds?http://uk.farnell.com/tenma/72-8225/oscilloscope-2-ch-40mhz-500msps/dp/1739443

content: I would think that it's a pretty standard function for any DSO. Is there a button labelled "single" or something to that effect near the top right corner? If so just press it, set a proper trigger level and connect the probe to a signal source, or even just a 1.5V battery will do for a simple test.

content: Look at the trigger-mode menu, if there is an option for "single". After one trigger event the RUN/STOPP switch should light red.Can't find a proper manual for your scope. Only a short crappy datasheet. I think your scope is originally a UNI-T brand.

content: LOL I should RTFM before I post staring at me fright in the face. Basically in the trigger section there's a menu button. After that it's self explanatory even for me a NOOOOB. Next learn how to interpret the signal so the next time I interfacing with some ic using spi bus, am not scratching my head wondering if the ic is even saying anything.

content: I have yet to see any scope that didn't have a single shot option.... At either rate you may want to consider a DS2000Z or DS1000Z from Rigol for your next scope.

content: Main feature of any digital oscilloscope (DSO) compared to any analog oscilloscope is single trigger function. Just do a proper trigger once and waveform stays here - it is recorded in memory, can be reviewed, saved, etc.You cannot do single shot with an analogue oscilloscope (except for special cameras that clip on CRT screen, but that is just too slow/cumbersome/impractical/non real time/... for most applications).DSO in question must have single shot, look for DSO manual or trigger controls.If it doesn't have single shot it is simply not DSO by any standard (I would throw out such "DSO" right away...)
