I’m doing some work with analog synthesis, and needed a scope. Didn’t have space for an old/refurb Tek model, and didn’t have $$ for some of the higher end small units that connect to my system… The DSO Quad looked like a good choice.
I don’t think my use is going to get into the problems noted about analog bandwidth; I’m strictly going to be in the audio frequency range and below, no intent to use it for debugging high speed digital stuff.
But I do have some questions from other things I’ve read. The community Wiki talks about the voltage limit being 10Vpp, but other sites and the official docs say 80Vpp. Since I’m working with a +/- 15V supply I could easily get 30Vpp when measuring things, and I want to confirm that the higher value is correct and I’m not going to be risking frying something every time I use it with the 1x probes.
My other concern has to do with the dire warnings such as “never connect your DSO to OSX”…well, since my first step was to charge the thing, and my primary system is a macbook pro…I’ve already connected it to OSX. HOWEVER, I do not see the device as a USB drive on my system, which makes me think that the dire warnings are ONLY for going into bootloader/firmware loading mode. I do have boot camp and an Open Solaris server (which would very likely work just like Linux has been documented, even though it’s not supported).
But I wanted to confirm that as well…
So to summarize:
What is the actual Vpp limit on this device using the 1x probes?
Do the OSX warnings only apply for firmware loading mode?
EDIT: i suppose I should note that when I boot, firmware is listed as 2.6.0, SYS as 1.51, and APP as 2.52.
