高通在做TX cal的时候,sweep0~4的含义
看你要做什么,就用对应的sweep来组合,比如要做et校准,可以用2楼列出的4个sweep来做,又比如如果想只做apt校准,那sweep可以用0,1,4这四个sweep type组合。再比如想在et校准中加入firmware delay校准,再加一个相关的sweep
(1) XPT Swp1
Max Bias Linearizer (APT PA States)
Alignment Sweep (4 IQ Captures for M-Line Calculation)
RGI Delta Sweep
(2) XPT Swp2
RGI Delta Data Push
M-Line Calculation (EPT/ET)
Load Unity DPD EPT/ET
EPT / ET Meas Power DPD Construction (IQ Captures)
EPT / ET DPD Processing
(3) XPT Swp3
APT Linearizer
Load Calculated DPD for EPT
EPT Linearizer (fetch power)
Load Calculated DPD for ET
ET Linearizer
(4) XPT Swp4 Frequency Compensation Sweep
APT FreqComp
Load DPD tables
XPT Freqcomp
随便你想做什么都行,还可以继续加
