Yes we did measure the bandwidth...BUT..
For all these new gold diggers, before you turn your gold to lead...
The bandwidth is only valid in the latest Firmware..
See picture of a 2072, measured with different options.
The problem is the frimware versions...
Version 00.00.01.00.05 ONLY supports codes DSAB...DSAH
it does not support bandwidth changes.., YES it shows but is not.
Version 00.01.01.00.02, support codes DSAB...DSAZ
Codes DSA2...9 have no use, they open the model 2102, as also 2202, at the same time,
it is possible that Rigol use these codes for something else, we dont know,
maybe for some other maintenance options. And yes they seems to work oke.
