Problem with A26DLR


Hi,
I'm trying to control servo A26DLR (pdf data attached). If I understand correctly, control signal is 333hz (3ms) and range for change of waveform is between 1500 and 2100uS. I attached both pictures from oscilloscope(0 degree servo time and 110 degree servo time). Signal is between 5.3V and 80mV. When I'm connecting servo its movement is rather chaotic (waveform i showed in picture servo_live) high level is dropping to 3.3V. When I'm trying to use Maximum (2100 us), servo is moving between positions. This is documented in video "110_degrees_or_2100_microsecond.mp4". When I'm trying to change signal from 1500 and 2100 and vice versa, it's moving, but still some jerking is involved (as documented in video "Servo_max_to_min_min_to_max.mp4"). I wasn't able to attached video here, so I'm sending link with it(bellow).

Could some look into it and maybe explained what I'm doing wrong?

Thank you for your time
