Calibration Description
the same for all dynamic datapath profiles, gain indices
and frequency regions and so on The calibration need
only be performed on a single channel.
Tx DAC Initial This is used to calibrate the DAC for the required profile
Calibration bandwidth.
Tx Path Delay This is used to estimate the delay between the Tx input
Initial
and the Tx output.
Calibration
Rx HP ADC RC This is used to determine how much the unit R and C
Initial vary from ideal and then tune the HP ADC's
Calibration programmable Rs and Cs to obtain their desired values.
Without this calibration, the HP ADC's noise
performance will be negatively impacted. The HP ADC
could also become unstable. It is not used when only LP
ADC is used.
Rx HP ADC This is used to optimize the HP ADC output noise by
Flash Offset correcting comparators offsets in the backend flash. It is
Initial not used when only LP ADC is used.
Calibration
Rx HP ADC DAC It corrects for element mismatch HP ADC current. It is
Initial not used when only LP ADC is used. This is disabled by
Calibration default – uncalibrated performance sufficient.
Rx HP ADC This corrects the 50% duty cycle for external LO when
Stability Initial the divisor is 2.
Calibration
Rx LP ADC This is used to calibrate the LP ADC. The major purpose of
Initial using the LP ADC instead of the HP ADC is to reduce power
Calibration consumption. It is not used when only HP ADC is used.
Rx TIA Cutoff This is used to tune the 3dB cut-off frequency of the TIA
Initial filter.
Calibration
Rx TIA Fine This is used to compensate the mismatch in 3dB cutoff
Initial frequency between I and Q path. It helps to correct
Calibration quadrature error in analog domain, which simplifies the
correction in the digital domain.
Rx Tone Initial This performs an initial QEC calibration in wideband
Calibration systems for frequency dependent quadrature errors.
Rx Frequency This performs an initial QEC calibration for frequency
Independent independent errors for both narrowband and wideband
Error Initial systems.
Calibration
Rx ILB LO Delay This is used to adjust the analog delay between the
Initial inphase and quadrature LO components at the mixer on
Calibration the internal loopback path. This is not enabled currently.
Rx RFDC Offset This is used to mitigate the RFDC offset added due to LO
Initial self-mixing.
Calibration
Rx Gain Path This is used to calculate the path delay between the Rx
Delay Initial analog and digital attenuation blocks. This delay is then
Calibration used to offset the onset of Rx analog and digital
attenuations relative to each other to compensate for
the path delay between these blocks. It is independent
of gain index and frequency region. The calibration
needs only be performed on a single channel.
This is used to measure the delay from internal FIFO to
Rx DMR Path
sync detection time needed in DMR and P25 monitor
Delay Initial
mode.
Calibration
PLL Initial This is used to perform VCO frequency calibration, VCO
Calibration real-time temperature/aging calibration and charge
