Set the channel source to be read
Set the waveform mode to NORM
Obtain data from the buffer
The internal memory waveform data can
only be read in the stop state
Set the channel source to be read
Set the waveform mode to RAW.
Note: When the channel source of
waveform reading is MATH, the query can
only return the screen data and this mode
is not available.
Reset the waveform reading
Start the waveform reading
Get the state
Waveform reading thread finishes
Get the data in the buffer
Waveform reading finishes
Waveform reading thread is running
Get the data in the buffer
Continue to read waveform data
