PeakTech 4120 generator failure

[ferdieCX]

Hi to all,
In the university where I teach, we have a PeakTech 4120 that is failing to properly startup.
It is a chinese product that probably sells under other brands. I have seen a two channel model rebadged as Tektronix
Does any one of you have any technical information or clue about this device ?
Thank you in advance

could be his one ?

In their 1000 series

AFG1062


must be similar to the AFG1022 series ??   but tek on their site have multiples warnings of  not messing with the wrong model    do not flash on 1062  etc ...

Anything can be done under the hood,  change the front panels pcb ...  remove some buttons etc ....  rebrand it and voila ?


can you open the case and show us any pcb markings

with free registration   you have acces to their FW   but no 5 Mhz model as far as i know

downloaded their 1022 fw
1.21
1.22
1.23
1.24
1.27

Maybe you can  or someone else can extract the boot files or help you

is it under warranty ??

have you contacted Peaktech ??

It's not a tek, it's a Owon, likely "inspired" by the tek design.

Although it was almost never used, the instrument is about two and half years old, so no warranty
I opened it, and it is not very service friendly.
You have to dismantle it almost completely to gain access to the board.

wow  what a strange setup

an arm cpu module  year 2010  is that it


maybe some Owon FW updates ??

you see the pcb hardware ...  only thing i see,  there is a 3 pins  holes in row and we see TX RX  on them,   maybe some console port ??
