I set a 16 QAM modulation with SR= 10MSPS and Alpha = 0.35. Then follow the instructions on page 84 of the user guide to store the instrument state in a register. But when I recall the register, it jumps back to a QPSK mod with SR=1 MSPS which is the instrument default state. The user preset also is not working, I can't save my own preset.
Anyone had a similar problem?
