ADRV9001 EVALUATION SYSTEM
DMA disabled, Tx_interface enabled: 0s are transmitted.
►
DMA enabled, Tx_interface disabled: data in DMA is not transmitted and is lost.
►
DMA enabled, Tx_interface enabled: data in DMA is transmitted.
►
The following enum defines the Tx1 DMA trigger.
typedef enum adi_fpga9001_DmaTrigger
{
ADI_FPGA9001_DMA_TRIGGER_SMA_1
ADI_FPGA9001_DMA_TRIGGER_SMA_2
ADI_FPGA9001_DMA_TRIGGER_MCS
ADI_FPGA9001_DMA_TRIGGER_GPIO
ADI_FPGA9001_DMA_TRIGGER_TDD_ENABLE = 4,
ADI_FPGA9001_DMA_TRIGGER_IMMEDIATE = 5
} adi_fpga9001_DmaTrigger_e;
If using ADI_FPGA9001_DMA_TRIGGER_IMMEDIATE, the DMA transfers data whenever the DMA_Enable goes high (and has valid data
►
from the SSI).
If using ADI_FPGA9001_DMA_TRIGGER_TDD_ENABLE, the adi_fpga9001_TddConfig_t->ADI_FPGA9001_TDDSE-
►
LECT_RX1_DMA_TRIG signal is the trigger. When this signal goes high (programmed in the TDD config), the DMA is triggered and
transfers data whenever the DMA_Enable goes high (and has valid data from the SSI).
If using ADI_FPGA9001_DMA_TRIGGER_GPIO/MCS/SMA_1/2, the GPIO/MCS/SMA signal is the trigger. When this signal goes high, the
►
DMA is triggered and transfers data whenever the DMA_Enable goes high (and has valid data from the SSI).
The latest release uses the ADI_FPGA9001_DMA_TRIGGER_IMMEDIATE.
Tracking Calibrations
Enable/disable tracking calibration algorithms in the tracking cals tab. Certain algorithms can only be enabled in certain profiles. For example,
RX harmonic distortion can only be enabled if configured in the DMR, Analog FM, and Tetra profiles. It greys out and is disabled in the LTE and
custom profiles.
Enable and disable an individual tracking algorithm to observe its effect while transmitting and receiving a signal.
