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
Addr value
0x00 0x300
0x01 0xC00820
0x02 0x1D3F4128
0x03 0x7F
0x07 0x1999999A
0x09 0x4E2FFFD
0x0Е 0x08B5000000000000
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.
