I noticed when measuring the time delay from IQ samples going to the AD9361 to the time RF is present on the output port is approximately 16uS longer than expected. See filter settings and waveform below. I have read the other threads regarding AD9361 TX path delays and have not found an answer for such a large difference in delay. What am I missing?
Base Band Sample Rate = 500KHz
|Calculated Latency||34.188 us|
CH1: FB_CLK (CMOS Single Ended)
CH2: TX_DATA_0 (CMOS Single Ended)
A: RF Power
