Carriers
The Carriers tab (see Figure 247) provides access to the settings that determine device LO configuration. This page allows the user to:
1. Define Carrier Frequencies (default selection in the Carrier Configuration Mode drop down)
• Configure the LO
• Set PLL Retuning to allow or disallow PLL retuning when switching between Tx and Rx
• When Tx and Rx are using the same LO, but different frequency in the case of Low IF mode for example, when switching
between Tx and Rx, PLL must be retuned to lock. If Tx and Rx are using different LOs, there is no need to do PLL
retuning.
• Set carrier frequency
• Intermediate frequency is supported for RX. Recommended range from 490kHz to 20MHz.
• Set Rx1/Rx2/Tx1/Tx2 carrier source (internal or external, options vary depending of selected setup).
• If external LO is used then
• Set the divisor value
• TES informs the user about the external LO frequency that must be provided to the ADRV9002 transceiver at the External
LO input.
• If Internal LO is used, user has the option to select Best Phase Noise and Best Power Saving for their application. Note only
Sub-1 G frequencies are supported for Best Phase Noise option. This option changes some of the analog DC biases to reduce
the VCO voltage swing and as a result the power consumption.
