No, I don't think you need to update the firmware. The generator knows that you cannot transfer power into a HiZ load, so does not offer dBm (which is power, not voltage) option in HiZ setting. Change that setting and try again.
Also for future information remember that setting does NOT change the output impedance of the generator. It is always 50 Ohm. That setting changes the calculation to display the voltage or dBm across a load of the value you input.
salomonander:
It does work now. Awesome. Thanks mate!

Hello!
Please help me find a firmware dump for the microcontroller (GD32F207xxx), which is in UTG932/UTG962.
hp3310a:
I really like (to get myself) the OTG962E but I need +-8V sine output at 30MHz (16Vpp). From what I heard (in a thorough review by Kerry Wong
it should be possible to do when setting the output to HighZ mode.
In the datasheet it says under "Amplitude range"
" <=10MHz: 1mVpp to 10Vpp (50Ohm)"
" <=60MHz: 1mVpp to 5Vpp (50Ohm)"
which I find confusing because Vpp should be 20V and 10V, no?
Could an OTG962E user please confirm that one can output +-10V at >10MHz when in HighZ mode? Thanks!
electr_peter:
You are misreading Vpp definition. Vpp means voltage swing from negative peak to positive peak, i.e. 10Vpp = -5V - +5V
I can confirm UTG962E outputs 10Vpp in HighZ load (up to ~15MHz, in higher frequencies reflections may reduce amplitude) mode and 5Vpp in 50Ohm load (to over 50MHz). 16Vpp at 30MHz is not available.
EDIT: emphasis on 50Ohm/HighZ at the load side
