No. Overclocking is not illegal. John

John, I cannot understand your logic - it is ok for Rigol to overclock slow ADCs and deprive ADC makers from income but it is not ok to "overclock" a Rigol scope? Tom

Why ? What were you expecting from a 100Mhz scope ? You also snipped the following... "The modded Rigol compared very well with a 100Mhz Tektronix TDS 1012." Care to comment why a TDS 1012 also 'kinda sucks' ?

Youtube has been posting that warning for a while now. They are using/going to use features that are not supported in older browsers.. I had a choice to update to IE8 or FireFox on this older PC here, I went with Firefox. Seems to be ok.. |
