可能原因：
LeCroy Wave Series.lvlib:Read Command Error.vi->LeCroy Wave Series.lvlib:Error Query.vi->LeCroy Wave Series.lvlib:Initialize.vi->LeCroy Wave Series Acquire Waveform.vi中的扫描字符串 (arg 1)
The format of the CMR? response is not as expected. Make sure that the Command Header is not being reprogrammed from the value configured in the Default Instrument Setup VI, where it is configured to OFF with the command CHDR OFF. (Default Instrument Setup.VI is called from Initialize.vi.)
完整调用链:
LeCroy Wave Series.lvlib:Read Command Error.vi
LeCroy Wave Series.lvlib:Error Query.vi
LeCroy Wave Series.lvlib:Initialize.vi
LeCroy Wave Series Acquire Waveform.vi
