DS1074Z = 90 MHz DS1104Z = 125MHz So that means that the myth around the '70MHz / 100MHz scopes are a marketing thing' is busted for the DS1000Z series. I can tell you also that the DS2000 70 MHz and 100MHz scopes are different, I know this from my own measurements, I have both. |

The DS2102 does out of the box about 150MHz, not so with an stock DS2072......... I have not tested the A series. |

The chip they use has only switches for 20 -100 -200 -350 Mhz etc.. so there is no entry for 70 Mhz, what they do is playing with the gain a little. The differences are small. You can see that when u do a measurment with a signal generator with a compensating head. |

Just pumped the generated serial numbers from riglol into my brand new DS1074z - running on software version 00.04.00. They worked perfectly! I also tried uninstalling the keys using the SCPI interface and that works fine too - useful to know in case my 'scope ever needs to go back for repair. Thanks guys for all the work on this and making it so incredibly easy. :) Also thanks Rigol for having a poor key implementation...! ;D Si. |
