Good afternoon. I have some difficulties with programming the AD9910 in OSK mode. Could you tell me what I'm doing wrong.
Here is the Register Map
That is, I want to run the OSK in AUTO mode. At the output, I should have a carrier with a frequency of 100 MHz and a varying amplitude. But nothing happens. If I disable the OSK bit enable, then nothing happens either. When i wrote value frequency in SingleTone register (0x0E), a signal appears.
Please tell me what I'm doing wrong.
