Note : Bob's intention was to ebay this if he didn't get a buyer. However, I have bought it from him, so the pledge remains open and it can be bought from me instead if it succeeds. (I'm not donating the whole cost, sorry!) --[[User:Artag|Artag]] 12:54, 2 August 2012 (UTC) | Note : Bob's intention was to ebay this if he didn't get a buyer.

==Hacking== | |||
It's widely known that this oscilloscope can be hacked to operate the same as the 100Mhz DS1102E model. The hack involves downgrading to earlier firmware, executing some (subsequently disabled) remote control commands, and then upgrading again. There is a small, but not insignificant possibility of bricking, and also the possibility, not guaranteed, of recovering the bricking. | |||
There is some evidence that the modification is actually worthwhile : there is some programmable control of the front end which does indeed raise the bandwidth. The 1GSa/s limit is not changed, of course, but the display permits a higher maximum scan rate. Since the 1GSa/s limit is over both channels, this is only really useful in single channel mode : Despite Nyquist's theorum, in 2-channel mode the 500MSa/s sample rate is only really enough for 50MHz (10x bandwidth is usually the rule for reasonable fidelity on current DSOs). | |||
