I am considering getting the DS1074Z, and I am curious where is the info to actually hack it in this thread? :)   Also where is the best place to buy it over here in the US?

DSHA  makes a  DS1104Z with no options enabled .
DSHR  makes a  DS1104Z with all options enabled .

The 3dB bandwidth for the DS1104Z is approx 160Mhz.
The 3dB bandwidth for the DS1074Z is approx 90Mhz.

Minor correction to my previous post after some further investigation.

DSHA also enables the 500uV setting and another unknown, (at present), option.

DSEA is the correct code to change to a DS1104Z only. ( no options ). See table below.

 Code      DS1104z    Unknown     500uV setting
DSBA                                               X
DSCA                            X
DSDA                            X                 X
DSEA           X
DSFA           X                                  X
DSGA           X               X
DSHA           X               X                 X

So to change a DS1074Z into a DS1104Z with all options enabled except the 500uV/div (which does not work correctly at present),
the code  will be DSER.

It is possible to revert back to original, by using the SCPI command " :SYSTem:OPTion:UNINSTall " .

As mentioned in my previous post, the measured 3dB down bandwidth after changing to a DS1104Z, is approx 160Mhz.
All the tests were done on a DS1074Z with Ver:00.02.00.SP1.

Is this entered in on the screen or done some other way?
