Someone has hacked MDO4000C?
klaus11:
it possible to do it?
andyturk:
It's pretty straightforward to hack the application modules. As for the other features, I don't know of any successful attempts.
I have a MDO4034B and when it boots up, it does say something on the syslog about a 1GHz analog board. Sure would be nice to liberate that extra 650MHz. >:D
EDIT: The info about the 1GHz analog board is not in the "console log", it's actually displayed on the scope's GUI in manufacturing mode.

Super Abyrvalg!
For Upgrade bandwidth 1GHz, is it necessary to modify hardware ?, remove some capacitor or resistor ...
I have searched a service manual for some clue, but it is a useless manual
tmbinc:
I've hacked a DPO4034 (non-B) to enable full bandwidth by hacking the software - bandwidth seems to be software configured, and the pre-amplifier is actually populated. However only half the number of ADCs are populated, making this hack not super useful. I need to characterize the bandwidth but last time I looked I didn't have the right tools.
Then I hacked a DPO5034 (which is - hardware wise - similar to the DPO4034B, i.e. it has a separate frontend board), see http://debugmo.de/2013/03/whats-inside-tektronix-dpo5034/ , by removing the filter. I only did this on one channel, though. I also hacked the software for it to be detected as a 1GHz model so the UI behaves properly. (The 1GHz and 2GHz models usually have the advanced frontend board with the pre-amplifier, but the 350MHz and 500MHz models only have basic analog board). All of the DPO5xxx however have the same (full) ADC configuration, only the analog board is different.
(I'd guess the DPO4034B however would only have the half-ADC config.)
The MDO4xxx however (regardless of -, -B, -C) again have a similar design as the DPO4xxxB, full-ADC config (since they need half the ADCs for the RF part), and of course have the MDO-style analog frontend with the RF part.
What I don't know is if they have the pre-amplifier for the non-RF channels (which I think implies a SW bandwidth limit) or not (which would probably be a HW BW limit then).
Can you post the syslog, and pictures of your analog frontend?
