These are the reasons why I personally prefer analogue, even if that means losing the ability to capture single shot events.
Without a digital scope you are losing:
- single shot capture ability
- deep memory ability (capture and zoom detail, much better than dual timebase on analog)
- roll mode ability
- peak detect ability (much better than analog if you just want to capture glitches)
- advanced triggering features
- pre-trigger display capability
- FFT and other measurement capability
- signal decoding etc
- screen capture ability (for documentation)
- data dump ability (for analysis)
- waveform replay ability (like on the new Rigol 2000)
- infinite persistence
(have I left anything out?, probably)
Most of those things are massive advantages and new abilities enabled only by digital scopes.
All that, for giving up the ability to see real time intensity grading (unless you pay mega dollars), and maybe slightly more complicated to drive - hell yes!
And now you can get intensity grading (DPO-like) functionality on sub $1K digital scopes.
There simply is no contest any more.
You do not have a properly equipped lab unless you have a digital scope.
