Just did something for the freedom of my DG811
Unlike for justme1968, the 2. (finish 2.04 update) and 3. (FW 2.06) .GEL file were prompted for update and ran successfull (self-boot including for 2.06). Stock FW was 2.05 = same.
I am curious if the ":PROG:MODE DG992" is really necessary? After the first .GEL (which I had to install in boot with pushing HELP) the device turned into a DG992 as decribed, the *IDN? after re-setting SN and after the :PROG:MODE returned exactly the same values, as I could see.
Nevertheless: It works as described, and here's another
BIG THXs!!! to all who made this possible.
In thankful reply to Ewald1963, which helped me to verify the behavior of my DG811 (and justme1968, too):
1) Connect both outputs to my oscilloscope;
...
5) Turn channel 2 on again;
Instead of my 10MHz sine, the scope now displays something like a 10 MHz ramp (0V to +1V)!
Same here, I did it 4 times and got a sin (phased 180) or this ramp (rather a unsymmetrical saturated ramp).
Did it also @2kHz, with the same result.
1) Set frequency of channel 2 to something other than 10MHz (I set it to 11 MHz)
...
4) Select channel 2 and you'll see that channel 2 is now set to the same frequency as channel 1 (10MHz in this example)(!)
5) Turn on channel 2 and there is your sine again.
Similar. I got the same freq at CH2 and a sine. The "ramp" comes if both channels had the same freq before switching the counter on.

After updating to 2.06, the Home and Menu button are switched in function (as mentioned in the changelog) - but not when pressing HELP and Home/Menu ...
