ADF4350 - According to ADIsimPLL Report - Frequency Locking:
Time to lock to 1.00kHz is 430us
Time to lock to 10.0 Hz is 586us
Whereas the time to see the output signal at 2dBm output level on the specrum analyzer is 2.15ms at 3kHz bandwidth and 781us at 3MHz bandwidth. What could explain this variation?
