I tried with the SDG2122X connected to my SDS2504X+, and I couldn't get anything like that. I tried with the channel power button, and power cycling the AWG, and didn't get anything like that at all. Cycling the channel gave a clean waveform that simply ended/disappeared when disabled. No effect at all while power cycling the AWG. Even searching in History didn't give me anything like that. I dunno if the 2000 series is that different than the 1000 series in this regard. 🤷 --- End quote --- I got squarewave set up with 0V to 3.3V or there abouts. I used 5s period, since it only seems to happen from high level on. t also only seems to happen on channel 1.

I just tried to see, when the sinewave amplitude would decrese with rising frequency: It did increase to 4.17V amplitude, with a set up amplitude of 3.3V. Am i missing something? |

Just blew up the dust from my DG812 to check it once again. But found nothing new. --- Quote from: EvgenyG on May 17, 2024, 03:27:05 am ---The signal gen may change waveform/frequency on power down but not go higher than set amplitude/offset. Ideally it should just cut out. On power up, I expect exactly 0 volts until I press CH1/2 on buttons. --- End quote --- How else it can be since there is a mechanical relay that keeps the output physically disconnected unless user pressed the key to turn the channel on. Power disappears, the relay disconnects. Actually, there are a lot of relays as the entire voltage range is not continuous. According to the doc, it's broken into 10 scales, which are switched by the mechanical relays. No doubt a curious user can capture a nice trace for relay bounce event and show the screenshot. But I doubt it's something unexpected. |
