2. Could you attach the scope snapshot so I could understand further whether its showing the signal tri-stated or not. If you turn off the channels using toolkit, the channels are not powered down but tri-stated.
3. Yes. this is the method to choose which device (MAX V or Stratix 10 ) to program. Yes, after selecting the correct SW setting, then you can program the device using Quartus Programmer.

Here is the requested scope trace. I hope you can read it. We get this signal from the SMA outputs when the transceiver TX is off. Its frequency is ~7.0GHz. I triggered this signal it with itself, using an 8x frequency divider to get the trigger frequency in range. If I use one of the PLL output clocks (156.25 MHz) as a trigger instead, I get a composite of copies of this signal with three different starting phases.
We still haven't managed to trigger the 51Gbps PAM-4 output. Any suggestions or instructions would be greatly appreciated. (Please see my previous comment about our DCAs.) Thank you.
