PC连接示波器。
示波器trigger后，PC读取到第一次数据。
如果下次trigger没有发生，使用:WAV:DATA?， 仍然采集到了第一次的数据，请问，如何清除掉上一次的数据？

You can use :DISPlay:CLEar to clear waveform data, but the next time you query for :WAVeform:DATA?, it will time-out and return a +109,"No Data For Operation" error. Instead, you can use the :TER? query to find out whether the trigger has occurred before sending the :WAVeform:DATA? query.

thank you very much!
