I am still trying to get the Phaser up and running and I stumbled across the next problem where some insight might be helpful.
Simple question first: Is the Phaser with upconverter supposed to be deterministic?
For me this is currently not the case. First of all I don't think this can work when using the internal 125 MHz reference from the Kasli. The maximum phase detector frequency of the TRF is below that, so I have to use an R-divider, which introduces a random phase offset. Any objections?
So, I guess I have to use an external reference with lower frequency, which I feed into the Kasli and the Phaser. As the 125 MHz have to be an integer multiple of that reference, I cannot use a common 10 MHz, right?
And is it also correct, that I have to modify the source code to tell Kasli/Phaser which external frequency is applied? I could not find any configuration value for that.
Thanks a lot
