毫米波用户需要通过测试连续波来确认TI毫米波芯片****射频信号的频率的准确性。用户对联参考设计板上进行****天线的连续波测试有不同的测试要求。下面介绍三种不同测试场景的测试流程。
测试条件：
硬件平台: MMWCAS-RF-EVM (revE)/MMWCAS-DSP-EVM
PC软件: mmwave studio 3.00.00.14
AWR2243 ES1.1的固件补丁: mmwave_dfp_02_02_03_01
频谱分析仪
测试场景一
1. 测试要求：对级联板上每个AWR2243所有3根****天线同时****连续波的测试。
2. 测试流程：
先在mmwave studio里运行下面的脚本进行所有4片AWR2243的参数配置。\mmwave_studio_03_00_00_14\mmWaveStudio\Scripts\Cascade\Cascade_ConfiguraTIon_ContStream.lua （测试脚本已经包含在mmwave studio里）
然后运行下面的脚本。这个脚本会先使能芯片Slave 3的连续波****，然后使能Slave2， Slave1，Master芯片。接着停止所有芯片的信号****。最后保存相关ADC数据到SSD硬盘上，传送给PC。\mmwave_studio_03_00_00_14\mmWaveStudio\Scripts\Cascade\Cascade_Capture_ContStream.lua（测试脚本已经包含在mmwave studio里）
通过频谱仪抓取和观测芯片的****信号。
测试场景二
1. 测试要求：对级联板的AWR2243 主芯片（master）的单****天线进行连续波的测试。
2. 测试流程：
以主芯片的TX0天线为例 (RadarDevice1)
a. 配置主芯片。
在mmwave studio里运行下面的脚本：
Cascade_ConfiguraTIon_ContStream_master_example.lua （具体内容见附录）
运行脚本后的mmwave studio界面信息如下：
b. ****连续波。
运行下面的脚本：\mmwave_studio_03_00_00_14\mmWaveStudio\Scripts\Cascade\Cascade_Capture_ContStream.lua（测试脚本已经包含在mmwave studio里）
c. 通过频谱仪抓取和观测芯片的****信号。
测试场景三
1. 测试要求：对级联板的AWR2243 从芯片（slave）的单****天线进行连续波的测试。
2. 测试流程：
以slave2芯片的TX1天线为例 (RadarDevice3)
a. 配置从芯片。
在mmwave studio里运行下面的脚本：Cascade_ConfiguraTIon_ContStream_slave_example.lua（具体内容见附录）
运行脚本后的mmwave studio界面信息如下：
b. ****连续波。
运行下面的脚本：\mmwave_studio_03_00_00_14\mmWaveStudio\Scripts\Cascade\Cascade_Capture_ContStream.lua（测试脚本已经包含在mmwave studio里）
c. 通过频谱仪抓取和观测芯片的****信号。
注意事项：
如果改变了AWR2243的ChanNAdcConfig_mult 参数（相对于上一次配置），用户必须对板子进行断电，再上电的操作。
常见问题：
1. 问题：如何使能、不使能主芯片或者是从芯片里的不同****天线TX？
答案:：用户需要修改配置参数的LUA脚本里ar1.ChanNAdcConfig_mult 函数的Tx0En/Tx1En/Tx2En 参数。关于这个函数的更多信息见下。对于Tx0En/Tx1En/Tx2En， 1表示使能，0表示不使能。
Int32 ar1.ChanNAdcConfig_mult(UInt16 RadarDeviceId, UInt16 Tx0En, UInt16 Tx1En, UInt16 Tx2En, UInt16 Rx0En, UInt16 Rx1En, UInt16 Rx2En, UInt32 Rx3En, Int32 BitsVal, UInt32 FmtVal, UInt32 IQSwap, UInt16 CasCadeMode) - Static device config API which defines configure both the Transmiter and Reciever channels of Radar device and also ADC data format output
_I_ UInt16 RadarDeviceId - Radar Device Id
_I_ UInt16 Tx0En - Tx0 channel
_I_ UInt16 Tx1En - Tx1 channel
_I_ UInt16 Tx2En - Tx2 channel
_I_ UInt16 Rx0En - Rx0 channel
_I_ UInt16 Rx1En - Rx1 channnel
_I_ UInt16 Rx2En - Rx2 channel
_I_ UInt32 Rx3En - Rx3 channel[b15:0] + (CascadePinOutCfg[b31:16] b16:ClkOutMasterDis, b17:SynOutMasterDis, b18:ClkOutSlaveEna, b19:SynOutSlaveEna, b20:IntLOMasterEna, b21:OSCClkOutMasterDis, b22:INTFRCMasterEna)
_I_ Int32 BitsVal - Number of ADC bits
_I_ UInt32 FmtVal - ADC output format[b15:0] + FullScaleReductionFactor[b31:16]
_I_ UInt32 IQSwap - ADC Mode
_I_ UInt16 CasCadeMode - CascadeMode(Single Chip: 0x0000, MultiChip Master:0x0001, MultiChip Slave:0x0002)
2. 问题：如何使能或者关闭级联板上不同的从芯片？
答案：用户需要修改配置参数的LUA里RadarDevice的设置。RadarDevice里dev1是主芯片，dev2、dev3、dev4是从芯片。
例如： RadarDevice = {1, 0, 1, 0} -- {dev1, dev2, dev3, dev4}, 1: Enable, 0: Disable
3. 问题：如何改变连续波的频率？
答案：用户需要修改配置参数的LUA里ar1.ContStrConfig_mult函数的startFreqConst参数值。
Int32 ar1.ContStrConfig_mult(UInt16 RadarDeviceId, Double startFreqConst, UInt16 digOutSampleRate, Char rxGain, Char hpfCornerFreq1, Char hpfCornerFreq2, UInt32 tx0OutPowerBackoffCode, UInt32 tx1OutPowerBackoffCode, UInt32 tx2OutPowerBackoffCode, UInt16 tx0PhaseShifter, UInt16 tx1PhaseShifter, UInt32 tx2PhaseShifter) - Continuous Streming Configuration API defines Configuration of the data path to transfer the captured ADC samples continuously without missing any sample to external Device(host)
_I_ UInt16 RadarDeviceId - Radar Device Id
_I_ Double startFreqConst - Start Frequency for each profile of chirp in GHz
_I_ UInt16 digOutSampleRate - ADC sampling rate for each profile in ksps
_I_ Char rxGain - Rx gain for each profile in dB
_I_ Char hpfCornerFreq1 - HPF1 corner frequency for each profile in KHz
_I_ Char hpfCornerFreq2 - HPF2 corner frequency for each profile in KHz
_I_ UInt32 tx0OutPowerBackoffCode - How much the trasmit power should be reduced from Max in Tx0 Channel
_I_ UInt32 tx1OutPowerBackoffCode - How much the trasmit power should be reduced from Max in Tx1 Channel
_I_ UInt32 tx2OutPowerBackoffCode - How much the trasmit power should be reduced from Max in Tx2 Channel
_I_ UInt16 tx0PhaseShifter - The additional phase shift to be introduced on Tx0 Channel
_I_ UInt16 tx1PhaseShifter - The additional phase shift to be introduced on Tx1 Channel
_I_ UInt32 tx2PhaseShifter - The additional phase shift to be introduced on Tx2 Channel(b0:15) + ForceSelect(b16) + VCOSelecct(b17))
