aveform in the oscilloscope.
A waveform is sent (programmed) in two command sequences. The first
sequence selects the waveform register number, programs the waveform
administration data, and programs the number of samples. The second sequence
programs the samples, including a checksum. Each sequence is synchronized by
an acknowledge response.
You can use the

back to the oscilloscope.

otherwise, an execution error will occur.
