I'm trying to do BPSK using RAM modulation mode in AD9910 Eval software. How can I define the out frequency for the waveform? I already have configured a ram.txt file for output wave phases.
EDIT: I've been able to set the out frequency by editing the FTW using debug window. Now what I'm trying to figure out is the difference in timing each time I switch between a RAM profile. I have a 0 degree phase at profile 1 and 180 degree phase at profile 2, zero crossing checked. Every time I switch from profile 1 to profile 2, I observe a difference in time it takes for the phase to invert. I'm doing this by setting my scope on single sequence mode, and having it triggered by profile pin (P_1 is connected to scope). Can any one guide me why there difference is there?
