Hi I know it's been a while and I'm probably out of luck but is it still possible to hack it even after they locked the SSH acess?
I read the first 2 pages of replies and it said you could downgrade the Firmware to version 1.8. Hack it, and then update the firmware to current.
You might want to read all 9 pages to see what all the latest developments are.
The Instek scope I would really like to hack is their MDO 2000. I've seen 1 comment ever with a guy claiming he did it, but never a post saying how to do it!
If I could get a MDO 4 channel scope for $1,400 then do a free update to unlock the 200MHz and all the decoding that would be very tempting indeed!

Apps installed, too. Datalog, digital filter, DVM... and SSH (last one has been somewhat orgasmic)
SSH app installed with Danymog's SSH.7z file posted in reply #226. However, I'm not sure how password reset is supposed to work. I tried setting a user password in I/O->ethernet menu, also resetting (to what?) password in SSH app, but I was unable to log in until I tried the password posted by wgoeo in reply #3
Now I'm in
@Danymog: so now it's known how to write Lua apps that work in these scopes, I guess...
Many thanks to all contributors.
Hello there. I have a GW Instek 1104B and I wanted to install the hacks. I managed to downgrade to 1.12 (boy, the scope is picky with USB flashdiscs), install most of the licenses and upgrade back to 1.29 successfully. However I couldn't install the Spectrum Analyzer. Is there a way to get it working or is it simply not supported at all on 1104B?
Also is there a way to enable the Fix 4 Measurement setting?
Got my GDS-1054B this afternoon. It has firmware 1.28. Serial decoding was already enabled. Firmware 1.29 just adds a couple translations so I'm leaving it out.
Downgrade wasn't needed. All done straight in FW 1.28.
Upgraded with the file posted by Mortymore (reply #83). Edited to change lines 26-27 so it gets the last clear code posted by wgoeo (reply #136)Code: [Select]a[0] = (a[0] + ((16 * a[1] + 0x19495CFF) ^ (a[1] + k) ^ ((a[1] >> 5) + 0x257130A3)))|0;

Changes saved. Extension changed to .html. Loaded in web browser (up-to-date firefox). Worked like a charm.
SA option doesn't work. I wasn't expecting it to work, but after reading some previous post, I tried it. So it didn't worked for me, either.
BW upgraded to 100 MHz. Segmented memory and search enabled, too.
Apps installed, too. Datalog, digital filter, DVM... and SSH (last one has been somewhat orgasmic)

There are contradictory reports about GDS1054B bandwidth on this thread. So I got one of Leo Bodnar's pulsers, just because curiosity got the best of me.
I tried the pulser on my improved GDS1054B. Used 50R inline termination. 1x attenuation. Capture is attached.
Since I'm not sure I did it all right, if you have any suggestions, I will try to put in practice. I'm on a hurry now, I have to get out for some days, but I'll do once back at home
2.8 ns risetime is 100MHz+ BW ... We can safely assume it is not 50 MHz anymore... You did unlock something...
The more channels I activate, the (much) worse rise times... 5 ns and more with all channels activated? I could gladly take more screenshots if (any of) you have more suggestions
more channels = lower sample rate.
FW 1.31 available:
Version 1.31
The channel's deskew range are expanded to +/- 1us.
