Hantek HDG2002B AWG: 5Mhz or 100MHz? Let's see!

I'm not sure if this is new, but I have just noticed that when modifying parameters for a wave (say square) such as the amplitude or offset via the keypad only, the FG does not actually change the output until I adjust the value with the jog wheel. Anyone else have this issue?

EDIT: if I modify the frequency in the same way, it is updated as soon as I press the correct unit on the keypad.
Cyber7:
I've always had to press an Fx key to select the unit of measure after entering a value with the keypad, no matter the parameter. Testing after selecting a square wave output on chan1, I enter F1 for freq, enter 999, press F3 for khz. Then I enter F2 for amp, press 3.3, and press F1 for volts. The display changes both times after selecting the unit, and they output also changes at that moment, checked via scope.

I still find it strange that commands via USB or via the test_cmd utility do not update the front panel. It should be a simple matter for the devs to simulate the key presses at worst. It'd be interesting to spy on the d-bus messages and see what goes on there.

This is a very standard feature when there is a keypad - you have to push a unit key after entering the number.  If you just push 2, is that 2 Hz, 2 kHz, 2 MHz, or 2 GHz?  Or perhaps 2 mV, 2 uV, 2 V, 2 dBm, 2 dBV, 2 dBmV, or 2 dBuV?  All of the test equipment I have that has keypads actually has dedicated unit keys that you have to push to commit the value.  If there are no units for the value, then you generally just push the Hz key.

@Cyber7: sorry, I wasn't clear; I select Duty Cycle, then on the keypad enter 10, then on the Fx keys select %. The display will then update but I will not see the output update with the new duty cycle value. If I then use the jog wheel to adjust the duty cycle, the output will snap to the display value and follow the display.
Cyber7:
I do believe you've found a bug! :scared: If I do the same on a square wave, the duty cycle updates on the GUI, BUT fails to update the waveform output after pressing the the % key to commit the value. The same occurs with a Ramp waveform with the symmetry setting.

Amplitude and offset are not affected. I need to plugin both outputs to verify the phase setting.
