I recently purchased a used analog Tektronix 453 and I want to capture some single shot transients. I also want to "save" the waveform so I can more easily measure things like peak to peak voltage of the transient. I know you can review saved one-shots in modern oscilloscopes but do analog scopes also support this useful feature?
In the manual, I see that single-shot trigger allows for "photographs" of the triggered waveform. However, after my trigger is activated, the waveform disappears. Changing the time/div or horizontal display doesn't show that any waveform is "saved". I am not sure how you would be able to photograph any transients since your window for taking the photograph would only be as long as your one-shot duration.
I would imagine analog memory to be much more expensive than digital memory but I don't understand the usefulness of one-shot captures without the possibility for later analysis.
