Has anybody enabled Tracking Gen on Agilent N9340B?
analogRF:
I was wondering if someone have found a way to enable the TG on N9340B or any other options for that matter.
There are interesting functions such as OptionCodeGenerate, OptionCodeVerify, GenLicense, readOptionLicense, etc...buried in the firmware
but I am a total idiot when it comes to firmware dis-assembly and reverse engineering, so I have no idea what is what in there but
there must be a way for those in the know...
The processor is Sharp LH7A404 (32bit ARM922T core) and it is based on vxWorks.
Actually the serial console is easily
accessible without even opening the instrument! Just open the battery door! however it is not TTL level (RS232)
EDIT: there is a MAX232 chip a few blocks away on the back side of cpu board if you really want to have TTL levels
analogRF:
BTW I have downloaded all the files from the internal flash memory. I guess they also could be extracted from the downloadable firmware file as well but with the serial console easily accessible, I just copied the whole thing on a USB stick but I have no way of knowing how the options can be
enabled.
I am guessing perhaps a method similar to what people did for DSO6000A oscilloscope might be applicable here too but I have no idea how that one came about either...

Can you drop the files somewhere?

Joining the “project”. Some questions:
- is there any official way to install option keys on this device?
- how does the serial console look exactly? (having some “anchor” helps identifying the handling code)
