Step 1: Send the query to get the data of waveform.
Query message:
C1:WF? DAT2
Response message:
The head of message: C1:WF ALL. These are followed by the string
#9000000070, the beginning of a binary block in which nine ASCII
integers are used to give the length of the block (70 bytes). After the
length of block, is beginning of the wave data. ―0A 0A‖ means the end
of data.
Step 2: Calculate the voltage value corresponding to the data point.
Using the formula: voltage value (V) = code value *(vdiv /25) - voffset.
