CRO <ding!> got it. ;-) And yes, we still say it for non CRT scopes too! And remember too, it's "sole-der", not "sodder" :-P Dave.
From: Tim Williams on 6 Dec 2009 23:18 I never was too impressed with digital scopes. None of them have nearly enough buttons, so you spend all your time wading through menus. The Rigol I've used (don't remember the number) has awful menus, they are not always quite what they say they are, and they take forever to go away. Some digital scopes have better refresh than others. The HP (Agilent??) 54622D's in all the labs at school here work fairly well, though at least two button presses are required to reach any given menu option. Refresh is okay, though still chunky on slower sweeps (>1ms/div). My impression of the cheapass Tek TDS's (the thin rectangular ones) is similar to the Rigol. I'm most familiar with my Tek 475, but it would be nice to have storage, single sweep* and averaging. One of those intermediate scopes, the ones with analog AND digital, they're perfect for everything. *Just because it's an analog scope doesn't mean you don't get storage or single sweep type readings, it just means it takes more setup. This photograph was taken with a 10 second exposure, capturing three photoflash discharges: http://webpages.charter.net/dawill/Images/Photoflash_Discharge2_sm.jpg Tim -- Deep Friar: a very philosophical monk.
