Re: EEVblog #978 - Keysight 1000X Hacking

I soldered the components to turn my DSOX1102A into a DSOX1102G, and I got the function generator to work but the amplitude of the signals is too high and causes signal clipping.
If I set the amplitude to a lower values the signals look fine.
When I traced back the signals, I could see it is the DAC itself that is outputting the larger than supposed amplitude and not the opamps that I soldered. It seems like the function generator is missing a calibration.
Can anyone who tried this let me know if you experienced a similar issue and how it can be fixed?
Thanks

I had that and it was fixed after running a user calibration. The scope however needs to be modded to the proper model with the strapping resistors.

Hello all,
I did go thru all thread, great work! thanks for effort, now I am happy user of DSOX1102A.
I have a couple a questions:
 - Is fercsa.ksx can be applicable for FW 01.20 ? Found answer in post #767
 - Is anybody tried solder not populated components for signal generator?

Thanks!

Hi All I found all answers thanks.
I did order parts, but I disappointed with BNC connector... The BNC jack which used in DSOX 1102X is non-standard...
Is anybody know part number for BNC which Keysight use?

Thanks

Did you find a full list of the other non-populated signal generator parts, including capacitor and inductor values?

I am going to start with: https://www.eevblog.com/forum/blog/eevblog-978-keysight-1000x-hacking/msg2544486/#msg2544486
The unspecified caps and inductor I am going use some regular value - I have standard kit of caps and inductors.
But I stuck with BNC it has smaller layout than regular BNC jack...

No ( since layout size for mounting posts biggest then layout at the PCB...
I already bought nice metallic BNC jack with the same size but it not fit.
I just wondering is any other BNC size for mounting posts is exists or Keysight use some custom BNC jack.

Do you think this BNC connector might work?

It took me months to find the correct BNC for the 1000X (EDUX1052A) and this one fits perfectly: https://fieldcomponents.com/RFB-1112-1B.html
