Is the bandwidth on DPO4000B software upgradable? I dont mean to 1GHz but something like 350MHz to 500MHz or 100MHz to 350MHz
depends what you mean with "software upgradable"... there's no official way to do it, but there are only 2 types of boards for the DPO4000B (physically), the 2.5GS/s version, and the 5GS/s version (plus DPO vs. MSO, of course). I didn't check, but what does abyrvalg say in the MDO4K thread ? I'm pretty sure some 'admin' commands can alter te model ID, and thereby the bandwidth, within the boundaries of the installed h/w, i.e. max 500MHz for the 2.5GS/s version.
Would be easier to know what model you have, what you're looking for, and have some high-res pics of your AFE board...
