Someone has hacked MDO4000C?

--- Quote from: analogRF on March 07, 2021, 01:08:12 am ---does it make any difference if one uses e.g. BW2T54 instead of using 500MHz for bandwidth upgrade? I mean for MDO4000C.

On the MDO4054C-SA6 I have, liberating it to 1GHz BW with an option key introduces some relatively minor vertical offsets, and the red banner "WARNiNG: This oscilloscope is not compensated". Running an SPC fails. Reverting back to 500MHz, those minor offsets disappear again, as does the red banner warning.

When I add or remove options, I still use 500MHz even though it's a 500MHz factory unit. When opening up to 1GHz, I include both 500MHz and BW5T10 options.

On the other side of the coin, on the MDO3014, liberating it to 500MHz with an option key seems to be seamless.

Of course, this is purely anecdotal, although my understanding is that the MDO3000 & MDO4000C share some similarities.
Howardlong:
FWIW, I discovered over the weekend that at least some bandwidth upgrades on the MDO4000C are now discontinued.

e.g., MDO4BW5T104-SA 500MHz to 1GHz w/SA.
Howardlong:
Here's a .vbs I use to remove the red banner.

Set your target IP address appropriately.

Sometimes I have to run it a couple of times if the toggle settings aren't in the expected state: it does nothing more than automatically push front panel buttons and turn knobs programmatically.

What's the difference between discontinued, and selling these options at prices higher then an MDO4104C-SA6 at many brokers ?   :wtf:
(might not be totally true in your case, but definitely for my MDO4024C-SA6)
analogRF:
I have a MDO4034C which I would like to upgrade to 500MHz.
But in the python scripts there is one BW3T5 option with two different masks and one is for 300MHz to 500MHz
and the other is for 350MHz to 500MHz. Obviously for MDO4000C it has to be 350MHz to 500MHz
but both of them are named BW3T5. If i generate the key and then validate it, it says 300 to 500.

So I am wondering which mask (0x40000 or 0x20000) works for 350M to 500M on MDO4000C?

my other question is that is this going to cause the same RED warning message about calibration that Hwardlong experienced with BW5T10?
