I tried it on my SDS2204X scope, but after it installed I could not get any traces to display on the screen. All of the buttons worked, menus came up, it reported itself to be an SDS2304X, but alas, no traces. I reinstalled the original 1.2.2.2 firmware and it's back to being its old self. Any ideas?

Have you done the HW patch (caps removal)?

swperk:
No, I haven’t removed the caps yet. I planned to do just that once I verified that the patch worked. Unfortunately, not only did the patch make all the channel traces disappear, it also did not enable the power analysis option (the only option on my scope that wasn’t already installed). So I will be waiting until I can figure out how to get the patch working to make the hardware modifications.

The patch worked perfectly!!

It's not supposed to activate any Options and it's not supposed to make the channel traces work at 300MHz with the caps on!

Did you even bother to read this?

swperk:
I had been reading several threads other than this one about enabling the SDS2000X power analysis option, and mistakenly attributed that feature to your patch. For that I apologize.

In any event, as I mentioned in my original comment, installing the patch made the scope unusable in that no traces were displayed. Fortunately, I was able to reinstall the original firmware and restore everything back to the way it was.

I understand that it is necessary to modify the hardware (caps) to get the full bandwidth, but is it also necessary to remove the caps just to get the traces to display? I wouldn't expect that to be the case.

tv84:
No, you don't need the SW patch for the SDS to work as a 300MHz unit.

You just need the HW patch.

What you saw is probably the result of applying the SW patch without the HW patch. No one had done that before.

So I think you could do the HW patch only, as several guys reported success. The SW patch is somewhat aesthetic.

Well, with your test, we confirm that it's not so  aesthetic as one might imagine.  So it was an involuntary step in the evolution path!
