Waveform Data
0x70 Data waveform starting address
Normal/Average acquire mode: each sampling points contains one 8-bit char.
High resolution acquire mode: each sampling points contains one 16-bit short integer.
Peak/Envelope acquire mode: each sampling point contains one 16-bit short integer, the
low 8-bit char is the min, and that of the high 8-bit char is the max.
Note :
The time of each sampling data :
Acquire time of the first data + sequence number of the data * waveform sampling data poing time interval
The amplitude of signal :
Normal: sampling data * (vertical scale*8/0xFF) + (-4*vertical scale + vertical offset)
High resolution: sampling data *(vertical scale*8/0x7FF) + (-4*vertical scale + vertical offset)
Gating : It is used to set the memory depth of the Save Waveform, and the corresponding acquired data of the
screen or whole memory depth data can be selected.
Save : It is used to complete waveform save according to above settings.
