Here are some DHO914S U/I findings that I really don't like and that don't make sense IMO: When changing parameters with encoders 1 and 2, and crossing decade boundaries (i.e. the unit multiplier changes), the digit that's going to be adjusted changes as well.
Example: In FFT, I manually set center frequency to 1kHz. This parameter gets automatically linked to encoder 1 (it's a pretty clever approach to link the lastly adjusted parameter to one of the "universal" encoders -- I like that). Now I use encoder 1 to increase the center frequency, it affects the 10Hz digit, so far so good. If I reverse the rotation, as expected the 10Hz digit gets decremented until I reach 1.00kHz again. If I continue to decrement, the next center frequency is 990Hz, only to decrement the 1Hz digit afterwards.
To me, this unaccounted digit jumping is utter nonsense. Moreover, if I press the encoder, the center frequency gets (re-) set to 1MHz, far off the range that had been selected before. I think for adjusting numeric parameters, the twist/push function of the universal encoders could have been utilized much more conveniently: Twisting changes a selected digit and stays on the (decimal) digit regardless of multiplier changes. Pushing the encoder toggles through the decimals/digits to be changed. The "reset" function is in most cases useless or rather counterproductive, especially if a wide range is covered by the parameter. There's the touchscreen pop-up keypad available to enter a numeric value if a wide-range adjustement to a certain value is desired.
I feel like complaining to Siglent who kept this same behavior on their legacy AWGs since a long time, though there it's a little bit worse still.
Stay on the digit without exceptions!
