I've got a DS1074Z-S... I was disappointed that the sig-gen couldn't make a 25MHz square wave, though it could make a sine wave up to 25MHz that looked good. With all the channels on and a sig-gen running, the control response get's a little slow, but it isn't unusable by any means, and not too annoying. It would be more annoying if I was using it for business where I spent hours with it each day, but I seem to use it in spurts so it is REALLY quite nice for that. It has decent save-to-usb function, though I seem to remember it having trouble with an 8 or 16GB USB flash drive. An older/cheaper/smaller flash drive has no problems. It comes with ethernet too, which I've not really used, but there were some folks developing custom Windows software (I don't think the source was open, though I remember it was based on some National Instruments core packages... I also remember thinking the open-source libvisa might be able to hook up to the scope). There are also some hacks you can do, for things like zooming in further than bit-depth has resolution for (aka digital zoom), and also for more controversial modifications.
I'm quite happy with it, though I was QUITE bummed out the day I was trying to generate faster and faster square waves to test some relatively high-speed digital stuff (I was starting from 1MHz and when the protocol seemed to work, I was planning to increase freq until the max 25MHz I thought it could drive... until the wavegen freq for square maxed out) On Thu, Jul 31, 2014 at 2:20 PM, Sova <[email protected]> wrote: > Hey guys, > > > > I’m looking at getting a scope to setup a basic test bench at my place. > Mainly I’ll be using it to repair amateur radios, amplifiers, and maybe some > debugging of digital circuits later. > > > > There is a guy on CL that is offering me an older Tektronix 2252 100Mhz > analog scope with digital storage and integrated volt-meter for $350.
