手里有太安捷伦DSOX1102A，70MHz的，测量200MHz信号完全是直线一条，很是不爽，遂在论坛查找升级方式，根据gamalot的提示去eevblog爬楼，发现了升级方法。
记录在这里方便大家使用。
FERCSA大神放出了升级文件，破解好的，直接升级完就搞定了。
1，升级文件放入U盘，usb浏览文件就可以，升级时间3分钟左右。
2，eevblog上写了示波器A和G版都可以，论坛上升的都是G，我是冒险升的A。--no difference between "normal" and -G version。

抄录过来内容：
FW v1.1: https://bit.ly/dsox1102hack
MD5: ad84976ff2f5b044a21020436751c5c3
1.1 is the same as 1.0, it's just add a small guide while you updating.
Just copy my .ksx file to an usb stick then insert into your scope and open it with the built-in file explorer.
A few minutes later, when the screen turned to pitch black and every LED turned on make a cold reset (power off-on). Sometimes soft reset won't work..
A few times happened with me, if you can't load the firmware from the file explorer, just reset everything back to default and try again.
There are a few known bugs like the PWR, Power application, you can't select certain menu items.
Another one is BW50, I found some sub routines which relying on different frequencies like 50-70-100-200 but no mention of 500. It's not a big deal anyway because you can't go way beyond 200-220Mhz.
If you find something else just report it, then maybe it's fixable on assembly level without a bunch of work.
I loaded every possible options, so no difference between "normal" and -G version.
Also I put the original non-modified fw to the second image location as a fail-safe. You can switch to it with a serial cable by pressing 'space' then select '2' on the beginning of the boot process.
升级文件如下，请自己检查MD5：ad84976ff2f5b044a21020436751c5c3

有人升级1102G成功，在595楼有说明和图，« Reply #595 on: March 19, 2019, 04:58:10 pm »。升级过程借他的图展示一下：
1.选择升级文件：
2. 开始升级
3. 升级过程
4. 升级前信息
5. 升级后信息
升级后测试200MHz信号测量ok。
另外提示一点：看其他论坛有人说最新版固件破解不了，这个我不知道了，这个是2018年12月的破解程序，所以这个时间前的肯定是能破解的。
