Send command TDIV?
Return TDIV 5.00E-09S.
Get the current timebase: timebase = 5.00E-09S.
The time value of the first data point: time value = - (5.00E-09*14/2) = -
35.00E-09(s) = -35(ns).
Send command SARA?
Return SARA 1.00E+09Sa/s.
Get the current sampling rate: sampling rate= 1.00GSa/s.
The time interval: time inter = 1/ sampling rate = 1ns.
So the time value of the second data point: value = -35ns+1ns = -34ns.
The following are two ways of waveform reconstruction:
Use Excel to reconstruct the waveform:
Use python to reconstruct the waveform: (See the code in Read Waveform
