[CMU200 Initialization]
CMU200 GPIB Address = GPIB0::20::INSTR
Time Out = 5000
GSM900 input cable loss = 1.2
DCS1800 input cable loss = 1.3
GSM900 output cable loss = 1.2
DCS1800 output cable loss = 1.3                      这里把CMU200的地址给出是20
                                                                    cable的线损

AFC_ARFCN = 70
N_AFC = 10
DAC1 = 4000
DAC2 = 5000                      DAC1和DAC2 可以得到SLOPE.然后算出其它点参数

MIN_FREQUENCY_ERROR_PPM = -17.0
MAX_FREQUENCY_ERROR_PPM = 17.0                        这一块6226平台不需要校准，622 5平台是需要校准的，AFC calibration

[RX path loss table]   这是校准pathlossz范围

MIN_INIT_AFC_DAC = 2000
MAX_AFC_SLOPE = 4.0
MIN_AFC_SLOPE = 1.0                   这是校准DAC，SLOPE范围

[Phase error table]
PHASE_ERROR_BAND = 0
PHASE_ERROR_ARFCN = 70
PHASE_ERROR_PCL = 10
PHASE_ERROR_RMS_ERROR = 1.5                相位误差有效值1.5度  不是2度么?
---------------------------------------------------------------------------------------------------------------
还有4个问题...我拿mtk校准软件校准扳子......有2个地方没过FT....
1..      class II    class lb                      这是就是接受灵敏度，不得大于2.4
2....   在CMU200 BS中设置的 Level -85.0 dbm   是不是输入电平 ?
                TCH level   -60 dbm(used) -20.0 dbm(unsed)   给一个低功率强制其发射
3..    在信号接通以后,  那个时间提前量误差 ---- 测的是什么？  是通信时间吗cotation update吗？
4.     在开关频谱那里....显示的Ref power 是什么概念 ???

还有这个呢?IP2校准是IQ校准么?还是 直接下变频中的DC offset校准?

APC dc offset=115   这是META工具可以更改这个数值，这个数值能更改校准功率的数值
