Local Oscillator (LO) Change Procedure
To set the LO frequency to a particular channel:
1. Verify that the internal ARM microprocessor is initialized.
2. If the device is in the RF_ENABLED state, first set it to the PRIMED state.
a. If in the SPI mode, do this by calling adi_adrv9001_Radio_Channels_EnableRf().

Description
Enable or disable RF channel (transition the specified channel between the RF_ENABLED and PRIMED states)
(this function only works if the channel is in the SPI mode).
Prime the specified channel (transition the specified channel between the CALIBRATED and PRIMED states).
Checks if the PLLs are locked.
Configures the loop filter for the specified PLL.
Gets the loop filter configuration for the specified PLL.
Sets the carrier configuration for the given channel.
Inspects the carrier configuration.
