Carriers
The Carriers tab Figure 324 provides access to the settings that determine the device LO configuration. This page allows to:
1. RX1 Port Switching allows to set up port switching depending on the receiver LO frequency. In this section, set the maximum and
minimum values to set up the switching for both the receiver channels. Note that this prevents the use of ORx channels.
2. Define Carrier Frequencies (default selection in the "Carrier Configuration Mode" dropdown).
a. Configure the LO.
1. Set PLL Retuning to allow or disallow PLL retuning when switching between the transmitter and receiver.
a. When the transmitter and receiver are using the same LO but different frequency in the case of low IF mode, for example, when
switching between the transmitter and receiver, retune the PLL to lock. If the transmitter and receiver are using different LOs, do
not retune the PLL.
b. In some configuration modes, such as TDD LTE, an "Antenna Diversity" checkbox appears. Use this checkbox to change the
routing of the LOs from Rx1/Tx1 and Rx2/Tx2 to all on the same LO.
2. Set the carrier frequency.
3. Intermediate frequency is supported for RX. Enable it by ticking the NCO box. Recommended range is from 490 kHz to 20 MHz.
4. Set the Rx1/Rx2/Tx1/Tx2 carrier source (internal or external, options vary depending on the selected setup).
5. If external LO is used:
a. Set the divisor value.
b. The TES informs about the external LO frequency to provide to the ADRV9001 transceiver at the external LO input.
6. If Internal LO is used, then select Best Phase Noise or Best Power Saving for the application. Note that the Best Phase Noise
option supports only Sub-1 GHz transmitter frequencies. Configure PLL power consumption to low, medium or high power. This
option changes some of the analog DC biases to reduce the VCO voltage swing, and as a result the power consumption. Set the
PLL calibration to normal or fast mode, and also set the PLL bandwidth from 50 kHz to 1200 kHz.
3. Frequency Hopping (select from the "Carrier Configuration Mode" dropdown).
a. To use the frequency hopping settings in the TES, see the
b. A prompt window pops up to use the "Frequency Hopping Wizard" on selecting this option. This wizard helps set up the FH
configuration in a step-by-step manner.
