darkstar49:

There are two options to address the issue...

The first one would be to patch the firmware to ignore the mismatch, the second is to alter the serial on either side, assuming they're to be identical, and not somehow 'related' via some computation...???
A detailed 'system config' dump of a genuinely 'normal' DPO3K could perhaps help clarify this, if someone has one at hand.
Do you know where the FE board's serial is stored ? Is it 'burned' into the FPGA or stored in some NVRAM on the FE board ?

How to alter the serial? That was my question. That's what I have been trying to do...

There are no eeprom on that board. Can they store it in a FPGA?


in a good scope, the SN of the atten board appears in the list on the config page. in this scope, it shows "No Ser"

analogRF:
the thing is I can change SN of all the othe modules, PSU, FP board, Display, Main board...it is just the Attenuator board that cannot be changed  |O |O |O

Very sorry, restart the thread, DPO3000 module crack someone successful?

Some interesting commands:
:PASSWord "password"- enable special modes
  Valid passwords:
  "XYZZY" - "user's password"
  "INTEKRITY" - "backdoor password" (this is the right one for other "backdoor" mode commands)
  "PUBLIC" - "public password"
  "TRESPASS" - "developer password"
  "MKTDEMO" - ???

:SETMODELID id - set model
  Valid IDs:
  0 - MSO/DPO3012 (MSO/DPO is selected by digital channels presense)
  1 - MSO/DPO3014
  2 - MSO/DPO3032
  3 - MSO/DPO3034
  4 - MSO/DPO3052
  5 - MSO/DPO3054

:HWAccountant:SERIAL - get/set serial number

:HWAccountant:INSTRumentid - get instrument id (no set here, it is generated from model+serial)

:HWAccountant:ACQBandwidth bw - bandwidth upgrade
  valid values:
  300
  500

:ARMDEMO pass, num_days - activate demo mode
   pass: "DontMakeTheWookieMad"
   num_days 1-30

I successfully connected to the computer through the LAN, and the following situation appears when I entered the command. What is the cause?
