TLS 216 Programmer Manual
commands starting on page 2–322 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 program on the diskettes that come with this manual
shows how you can scale data.
You can transfer waveforms from the logic scope to an external controller using
the following sequence:
1. Select the waveform source(s) using the DATa:SOUrce command. If you
want to transfer multiple waveforms, select more than one source.
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. If the waveform is a reference, set the Ref Display type to other than Off.
6. Transfer waveform preamble information using WFMPRe? query.
7. Transfer waveform data from the logic scope using the CURVe? query.
You can transfer waveform data to one of the four reference memory locations in
the logic scope using the following sequence:
1. Specify waveform reference memory using DATa:DESTination.
2. Specify the memory size for the reference location (entered in Step 1) using
the ALLOcate:WAVEFORM:REF<x> command.
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. Set the Ref Display type to other than Off.
7. Transfer waveform preamble information using WFMPRe:<wfm>.
8. Transfer waveform data to the logic scope using CURVe.
