waveform is the 22th byte "00", convert to binary is "00000000"
(Hexadecimal converted to binary (LSB)).
Step 3: Calculate the time value of the data point.
Using the formula: time value(S) = - (timebase*grid/2).
timebase: The timebase value.
grid: The grid numbers in horizontal direction.
The picture above as an example:
Send command
Return
TDIV 5.00E-08S
Get the current timebase: timebase = 5.00E-08S.
The time value of the first data point: time value = - (5.00E-08*14/2) = -
3.50E-07(s) = -350(ns).
Send command
Return
DI:SARA 1.00E+09Sa/s
Get the current sampling rate: sampling rate= 1GSa/s.
The time interval: time inter = 1/ sampling rate = 1ns.
So the time value of the second data point: value = -350ns+1ns = -349ns.
Use python to reconstruct the waveform: (See the code in
