External System Requirements for Tracking Calibrations
Different from initial calibrations, tracking calibrations are performed on-the-fly with real-time traffic data. Therefore, it is mostly
transparent to the users and fully controlled by the internal micro-processor. The external system requirements for users are as the
following:
Make sure external paths are available when running some tracking calibrations on external loopback paths.
•
When external loopback path after power amplifier is used (ELB2), a suitable attenuator must be chosen between the power
•
amplifier output and the observation channel input to prevent Tx output data from saturating the observation channel input.
When external DPD is employed in the system, it should time share with other Tx tracking calibrations to avoid conflicts.

Calibration Description
Tx PAC This is used to perform power amplifier correction.
Tracking Currently this tracking calibration in not available.
Calibration
Tx DPD This is used to pre-distort the transmit signal in real-time
Tracking to compensate for the power amplifier nonlinearity for
Calibration achieving higher power efficiency. Please refer to the
Digital Predistortion section in the User Guide for more
details.
Tx CLGC This is used to compensate for the power variation in
Tracking power amplifier. Currently this tracking calibration in not
Calibration available.
Tx Path Delay This is used to correct the Rx 2nd order harmonic
Initial distortion.
Calibration
Rx QEC WB This is used to correct Rx frequency dependent
PLOY Tracking quadrature error for WB applications.
Calibration
ORx QEC WB This is used to correct ORx frequency dependent
Tracking quadrature error for WB applications. Currently this
Calibration tracking calibration in not available.
Rx BBDC This is used to mitigate the Rx DC offset at baseband on-
Tracking the-fly.
Calibration
Rx RFDC This is used to mitigate the Rx DC offset at RF (analog) on-
the-fly.
Tracking
Calibration
Rx QEC FIC This is used to correct Rx frequency independent
Tracking quadrature error for both NB and WB applications.
Calibration
Rx AGC This is used to enable/disable automatic Rx gain control
Tracking operation on-the-fly. By disabling it, AGC stops
Calibration responding to changes in the input signal and will instead
hold its last gain index.
Rx RSSI This is used to enable/disable Rx signal strength
Tracking measurement on-the-fly. Currently this tracking
Calibration calibration in not available.
