I need a sure answer to a simple question. I have an AD9910 with which I control the
phase of a 53 MHz RF signal. During the first interval in my process the phase of the
RF is used to regulate "control variable 1". At a certain point of time in my process I
must move the phase of my RF output from where ever it might be to match the phase of a
second 53 MHz RF signal (neglecting control variable 1).
Can I ramp the POW phase offset word from say 0xFF30 upward rolling the number over
to 0x0000 and continue to say 0x0016? Will I get a smooth phase change as the POW
rolls over ?
I apologize that I do not have my hardware available to verify this myself.
I have to give a presentation in a couple days I want to make sure I am not lying.
If the roll over still produces a smooth phase shift the DDS is so much
better than say an analog voltage controlled phase shifter that can only shift
+/- 170 degrees.
