locations. You can specify the reference memory location with the DATa:DESTi-
nation command.
Each waveform that you transfer has an associated waveform preamble that
contains information such as the horizontal scale, the vertical scale, and other
settings in place when the waveform was created. Refer to the WFMPre
commands starting on page 2--314 for more information about the waveform
preamble.
Once you transfer the waveform data to the controller, you can convert the data
points into voltage values for analysis using information from the waveform
preamble. The GETWFM (get waveform) program on the disk(s) that come with
this manual shows how you can scale data.
You can transfer waveforms from the oscilloscope to an external controller using
the following sequence:
1. Select the waveform source using the DATa:SOUrce command.
2. Specify the waveform data format using DATa:ENCdg.
3. Specify the number of bytes per data point using DATa:WIDth.
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 WFMPRe? query.
6. Transfer waveform data from the oscilloscope using the CURVe? query.
You can transfer waveform data to one of the four reference waveforms in the
oscilloscope 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 DATa:ENCdg.
4. Specify the number of bytes per data point using DATa:WIDth.
5. Specify first data point in the waveform record using DATa:STARt.
6. Transfer waveform preamble information using WFMPRe.
7. Transfer waveform data to the oscilloscope using CURVe.
