Hi, There is a few things in your attached code which explain the error message from the socket. First of all, the problem is not related to the socket or...

Phase cycling may be performed in two ways using simpson. 1. Use the filter command to select the desired coherences. This method is absolutely preferrable. 2....

You're right. In this case you need to use multiple propagators each storing bits of the pulse sequence in between the filter-commands. Thomas -- ...

I tested the 90 time just as you would on the spectrometer. Pulse and acquire. As expected, the RF power level is the actual, not the effective RF and thus you...

And by analogy, if you set only the first order on, does that imply that there will be no second, even if the coupling constant was large enough that you...

About the reset command: The optional delay to this command allows you to start the pulse-sequence fragment at times different from 0. This is only relevant...
