Hi Gaby (@gabriela ),
I am sorry. I owe you a big apology…
I had forgotten that, on my GNSSDO, jumpers A and E are open. By default, they are closed:
If I close jumper A, I see:
If you are feeding a digital load, you will want jumper A to be closed. If you are only feeding high impedance inputs, like your 'scope, then opening jumper A avoids the overshoot and ringing.
I am sorry for doubting you - and the FS740!
I have put a big label on my GNSSDO to remind myself that the jumpers are open.
We will be releasing new firmware for the GNSSDO in a few days. It contains some improvements you may find useful. Please keep an eye on the Firmware Upgrade link. I will update that when v2.1 is released. I will also be adding a Dockerfile and instructions on how to compile the firmware locally using Docker (Desktop), just in case you want to make any firmware alterations of your own.
Please let us know if you need more help and thank you for supporting our products.
Best wishes,
Paul
