lp206:三汇和汉泰硬件都是一样的呀,可以互相刷固件,不过测到400M,那是太自欺欺人了吧 (2011-11-21 12:40)  看老外测试的指标。
100MHz = 0db
150MHz = 0db
200MHz = 0db
250MHz = -3db
300MHz = -6db
350MHz = -9db
400MHz = -12db
So it is not a true bw hack, but at least something. If you don't have another high bw scope and wish to measure/control
higher freq. this solution is good enough. The hadrware freq. counter (in the bottom status line) is anyway working
stable up to 410MHz.
至于你信不信,反正我是信了,老外非常牛。 |
