Data size digit
Indicates the number of digits used for the data
string that follows. The data size digit is 4 for 4000
points, 7 for 1M or 2M points.
Data size
Indicates the data size. The data size varies from
8008 (4000 points), 2000008 (1M points) or 4000008
(2M points).
Time interval
Indicates the time interval between two adjacent
sampling points in the floating point format,
compatible with IEEE 754 standards.
Note: The data is sorted in the little-endian format.
Channel indicator
Indicates the channel, 1 or 2.
Reserved data
An unused data block, 3 bytes.
Waveform data
The waveform data comprised of 2M data points.
Each point is made up of 2 bytes (16 bits), high
byte (MSB) first.
:ACQuire:MEMory
Query
