Preliminary Technical Data
In this structure, chanTrackingCalMask[] is an array containing calibration bit mask for channel related tracking calibrations
(chanTrackingCalMask[0] is the mask for Rx1/Tx1 channels and chanTrackingCalMask[1] is the mask for Rx2/Tx2 channels ).
The following enumerator type defines all the initial calibrations:
typedef enum adi_adrv9001_TrackingCalibrations

ADI_ADRV9001_TRACKING_CAL_TX_QEC
ADI_ADRV9001_TRACKING_CAL_TX_LO_LEAKAGE

Table 46 describes the mask bit assignment for tracking calibrations in the "adi_adrv9001_TrackingCalibrations_e". It also explains the
functionality of each tracking calibration. Note it is possible to select different mask for Channel 1 (Tx1/Rx1) and Channel 2 (Tx2/Rx2).

Calibration Description
Tx QEC This performs tracking QEC calibration for frequency
Tracking independent errors for the Tx path. It estimates the gain
Calibration and phase mismatch on-the-fly using the real-time traffic
data and apply the gain mismatch in the digital domain.
Similar as the initial calibration, currently it utilizes the Tx
path and an ILB path. If transmitted data is quadrature
modulated, this tracking calibration is performed, but it is
not used if the data modulation is direct modulation
(DM).
Tx LOL This performs tracking LOL calibration. It estimates the
Tracking LOL on-the-fly and applies the cancellation in the digital
Calibration domain. It utilizes the Tx path and an loopback path
(external loopback path preferred if available). If
transmitted data is quadrature modulated, this calibration
is performed, but it is not used if the data modulation is
direct modulation (DM).
Tx Loop Back This is used to track the Tx Loop Back Path Delay (could
Path Delay be for either ILB or ELB) on-the-fly. This information is
Tracking required for QEC, LOL and DPD tracking calibrations.
Calibration Currently this tracking calibration is not available. QEC,
LOL and DPD tracking calibration utilize the delay
measurement obtained from Tx loopback path delay
initial calibration.
