Transferring WaveformData from the Oscilloscope
Youcan transfer waveforms from the oscilloscope to an external controller using
the following sequence:
1. Select the waveform source(s) using DATa:SOUrce.
2. Specify the waveform data format using DATa:ENCdg.
3. Specify the number of bytes per data point using WFMOutpre:BYT_Nr.
4. Specify the portion of the waveform that you want to transfer using
DATa:STARt and DATa:STOP.
5. Transfer waveform preamble information using the WFMOutpre? query.
6. Transfer waveform data from the oscilloscope using the CURVe? query.
Transferring WaveformData to the Oscilloscope
Youcan transfer waveforms to the oscilloscope from an external controller using
the following sequence:
1. Specify the reference waveform using DATa:DESTination.
2. Specify the record length of the reference waveform using WFMPre:NR_Pt.
3. Specify the waveform data format using WFMInpre:ENCdg.
4. Specify the number of bytes per data point using WFMInpre:BYT_Nr.
5. Specify rst data point in the waveform record using DATa:STARt.
6. Transfer waveform preamble information using WFMInpre.
7. Transfer waveform data to the oscilloscope using CURVe.
