Hi, when i started messing with electronics about a year ago, i got myself a Rigol DS1052E basically, just to figure out, whether or not i really need a DSO and which features i do need and which i don't. Turns out i do need one, pretty much everytime i work on something. And while i still think the Rigol is a good buy, there are some features it lacks and some things, that just annoy the heck out of me. So, i think i should propably move on. So the question i'd like your help with is: to what?
What i need feature-wise:
4 channels
100 MHz
Serial Decoding on analog channels.
If it has a full LA i could do with 2 Channels. But i would use the LA almost exclusively for Serial stuff (I2C,SPI,UART) so 4 Analog Channels seems to be more versatile for my purposes, in the end that would pretty much come down to price i guess.
>1MPts Memory
Bigger Screen than the Rigol. Preferable VGA or better.
Now the 100MHz are negeotiable. So far i'm getting along nicely with the 50MHz of the Rigol, but i'd like to keep the new one for a while, and 100MHz seem like a good compromise between Bandwidth and price. If the Scope is upgradeable, 50MHz or 70MHz would be ok.
Now after the hard facts some of the Rigols annoyances i want addressed:
I want seperate vertical controls for each channel. The combined control of the Rigol drives me mad!
Also i'd like to have a dedicated "Singleshot"-Button. This Seems to be pretty much standard on all midrange-scopes i've seen so far, but i thought i'd mention it anyways.
Budget: Well basically, as little as i can get away with and as much as it takes to get what i want. But for the sake of argument let's say <2000€.
The scopes i have looked at so far that seem to fit the bill:
Agilent DSO 2014, also the seem to be strangely hard to find in Germany and i'm not sure if the BW is upgradeable, Also the options are a bit on the high side.
Rigol DS4000, looks good, but is a bit more expensive than i'd like.
Hameg HMO1024 - No seperate vertical controls
And as an aside it would be great, if it comes with linux software, I wouldn't hold my breath for that one though.
I'd appreciate your input and suggestion. Especially on other brands i missed so far (lecroy, tektronix?). Also i read here on the forum, that agilent sells off, demo-units and refurbished ones on ebay. Do you know if any other manufacturer does something simmiliar?
Thanks and Cheers,
