Waveform data locations
and memory allocation
The DATa:SOUrce command specifies the location of the data when transferring
waveforms from the instrument. You can transfer one waveform at a time.
You can transfer only one waveform into the instrument at a time. Each
waveform is stored in one of two stored waveform locations for 2-channel
models or one of four stored waveform locations for 4-channel models. You
specify the stored waveform location with the DATa:DESTination command.
NOTE. The instrument stores waveforms that are ≤2500 data points long. The
instrument truncates waveforms longer than 2500 data points.
Waveform preamble
Each waveform that is transferred has an associated waveform preamble that
contains information such as the horizontal scale, vertical scale, and other
settings in place when the waveform was created. Refer to the WFMPre?
commands for more information about the waveform preamble.
Scaling waveform data
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.
Transferring waveform
data
Data transfer times depend on data format, data width, and the speed of the
controller. Programming Examples on page 295
From the instrument. To transfer waveforms from the instrument to an external
controller, follow these steps:
1. Use the DATa:SOUrce command to select the waveform source.
2. Use the DATa:ENCdg command to specify the waveform data format.
3. Use the DATa:WIDth command to specify the number of bytes per data
point.
4. Use the DATa:STARt and DATa:STOP commands to specify the part of the
waveform that you want to transfer.
5. Use the WFMPre? command to transfer waveform preamble information.
6. Use the CURVe command to transfer waveform data.
To the instrument. To transfer waveform data to an instrument waveform storage
location, follow these steps:
1. Use the DATa:DESTination command to specify the stored waveform
location.
2. Use the DATa:ENCdg command to specify the waveform data format.
3. Use the DATa:WIDth command to specify the number of bytes per data
point.
4. Use the DATa:STARt command to specify the first data point in the
waveform record.
5. Use the WFMPre? command to transfer waveform preamble information.
6. Use the CURVe command to transfer waveform data.
